Item Management dilemmas in radiation associated pelvic sarcoma.(2005-01-14) Goel, Vineeta; Sarin, Rajiv; Shrivastava, Shyam Kishore; Desai, Sangeeta; Dinshaw, Ketayun ArdeshirItem Advantages of multiple algorithm support in treatment planning system for external beam dose calculations.(2005-01-14) ,The complexity of interactions and the nature of the approximations made in the formulation of the algorithm require that the user be familiar with the limitations of various models. As computer power keeps growing, calculation algorithms are tending more towards physically based models. The nature and quantity of the data required varies according to the model which may be either measurement based models or physical based models. Multiple dose calculation algorithm support found in XiO Treatment Planning System can be used to advantage when choice is to be made between speed and accuracy. Thus XiO allows end users generate plans accurately and quickly to optimize the delivery of radiation therapy.Item Management of locally advanced breast cancer: evolution and current practice.(2005-01-14) Rustogi, Ashish; Budrukkar, Ashwini; Dinshaw, Ketayun; Jalali, RakeshLocally advanced breast cancer (LABC) accounts for a sizeable number (30-60%) of breast cancer cases and is a common clinical scenario in developing countries. The treatment of LABC has evolved from single modality treatment, consisting of radical mutilating surgery or higher doses of radiotherapy in inoperable disease to multimodality management, which along with the above two included systemic therapy. Neoadjuvant chemotherapy (NACT) has made a tremendous impact on the management of LABC. NACT was initiated to institute systemic therapy upfront at the earliest in this group of patients with a high risk of micrometastasis burden. While NACT did not yield a survival advantage, it has however made breast conservation possible in selected group of cases. Large number of studies and many randomised trials have been done in women with LABC in order to improve the therapeutic decisions and also the local control and survival. With this background we have reviewed various treatment options in patients with LABC which should possibly help in guiding the clinicians for optimal management of LABC.Item Programmed cell death as a prognostic indicator for radiation therapy in cervical carcinoma patients: a pilot study.(2005-01-14) Bhosle, S M; Huilgol, N G; Mishra, K PPURPOSE: In clinical practice, radiation therapy often fails in cervical carcinoma stage IIIB and there is a need to develop a predictive assay for prognosis of radiation treatment outcome in cancer patient. We have attempted to evaluate the relevance of changes in Membrane Fluidity (MF) and associated apoptotic cell death in cervical cancer cells after first fractionated dose of radiation therapy to treatment outcome of stage IIIB cervical carcinoma patients. MATERIALS AND METHODS: Biopsies of 15 patients with histologically proven cervix cancer were collected from the patients before and 24 h after first fractionated radiation dose of 2 grays (Gy). Cell suspension made in Dulbecco's Modified Eagle's Medium (DMEM) were used for further investigations and cell suspension of cervix cancer patient were used to measure MF by fluorescence polarization method and apoptotic index (AI) was determined by Tdt dUTP Nucleotide End Labeling (TUNEL) assay. RESULTS: A substantial increase in MF and AI was observed in cervical cancer cells irradiated ex vivo . A significant correlation ( P P > 0.1) was detected between changes in MF and treatment outcome of patients. CONCLUSION: Preliminary results showed significant change in MF and a marked increase in percentage apoptosis of cervix cancer cells irradiated ex vivo . The changes in AI after first fractionated dose of radiotherapy in cervical carcinoma patients may provide a predictor of prognosis for radiotherapy in uterine cervical carcinoma patients.Item Three dimensional conformal radiation therapy in prostate adenocarcinoma: survival and rectal toxicity.(2005-01-14) Kannan, V; Sathiyanarayanan, V K; Sagde, S; Anand, Vivek; Almel, Sachin; Kapadia, Asha; Srinivas, VTechnological advances in radiation beam planning and linear accelerator based radiation delivery have led to the development of three dimensional conformal radiation therapy (3D-CRT). The 3D-CRT clinical treatment in our hospital was started in September 1998 and till December 2002, 51 patients with M(0) stage prostate carcinoma were treated. Treatment method consisted of pelvis and leg immobilization, planning CT scan, marking of planning target volume and organs at risk and 3D beam plan using multileaf collimated beam shaping through beam's eye view display. Network controlled 3D conformal radiation therapy was delivered with portal image verification. The median 3D-CRT dose was 72 Gy. Of the 51 patients, 35 were followed-up till December 2002 (minimum follow-up 2 years) in whom 32 were disease free and 3 had progressive disease. Eleven patients died, 8 of progressive disease, one due to second malignancy and two of intercurrent illness. Five patients were lost for follow up during 0 - 29 months period, after 3D-CRT. The acute rectal reaction (RTOG criteria) in 51 patients was grade 0 in 4, grade I in 31 and grade II in 16. None had greater than grade II rectal toxicity. The late rectal toxicity in 49 patients who had a minimum 6 months follow-up was grade 0 in 41, grade I in 3 and grade II in 5. Our experience suggests that a dose of 72 Gy by 3D-CRT can be safely delivered to the prostate and gastrointestinal tolerance during treatment and follow-up period was excellent.Item At the cross roads and a new beginning.(2005-01-14) Huilgol, Nagraj GItem Trends in basic, translational, epidemiological and therapeutic research in cancer.(2005-01-14) Sarin, RajivItem Neo-adjuvant chemotherapy with cisplatin and short infusional 5-FU in advanced head and neck malignancies.(2005-01-14) Aich, Ranen Kanti; Deb, Asit Ranjan; Ray, AmitabhBACKGROUND: Combination of radical surgery and radiotherapy is the standard management of head and neck malignancies. But due to considerable morbidity of surgery and associated cosmetic and functional deficiencies, often aggravated by adjuvant radiotherapy, many patients prefer only radiotherapy with its' decreased chance of survival. Proper surgical facilities are also not accessible to most of our patients. Neo-adjuvant chemotherapy and loco-regional management by surgery and / or radiotherapy have emerged as a viable alternative. AIMS: The purpose of this study is to find out the survival outcome as well as toxicity profile of Neo-adjuvant chemotherapy with cisplatin and short infusional (3 hours) 5-FU followed by radiotherapy in advanced head and neck malignancies. MATERIALS AND METHODS: From June 2002 to December 2003, seventy four patients with advanced head and neck malignancies were planned to be treated with Cisplatin (50 mg / sq. meter) on Days 1 and 2 and 5 - FU (600 mg / sq. meter) on Days 1, 2 and 3 by 3 hour infusion on Day care basis. On completion of four cycles of chemotherapy at 21 days interval, all patients were destined to receive 6000 cGy of radiotherapy to the loco - regional site. RESULTS: At one year follow up on completion of therapy, 57% patients were alive and 31% patients were disease free. These 31% patients enjoyed a good quality of life in terms of cosmetic and functional deficits. Toxicities were moderate and easily manageable. CONCLUSION: The study indicated that neo-adjuvant chemotherapy with Cisplatin and short infusional 5 - FU may be delivered on day care basis and results are comparable with Cisplatin and 96 hours continuous infusional 5 - FU. Thus avoiding the continuous infusional 5 - FU, 7 to 10 days in-patient hospitalization during each cycle may be avoided which is a constrain in developing countries like us.Item Radiation therapy for the developing countries.(2005-01-14) Bhadrasain, VikramItem Breast cancer in males: a PGIMER experience.(2005-01-14) Rai, Bhavana; Ghoshal, Sushmita; Sharma, Suresh CAIM: Male breast cancer is a rare disease representing 1% of all breast cancers and less than 1% of all cancers in men. Because of its rarity, carcinoma breast has not been studied extensively and this prompted us to carry out this retrospective study. The aim of the study was to observe the clinical and pathological features, evaluate the prognostic factors and to co-relate the outcome in patients of male breast cancer. MATERIALS AND METHODS: Thirty patients of male breast cancer treated in the department of radiotherapy from year 1996-2000 were retrospectively analyzed. RESULTS: The actuarial five- year disease free survival was 40%. Three out of 30 i.e. 10% patients had loco-regional recurrence and all of them had locally advanced disease at presentation. Distant metastasis occurred in 9 patients of whom 6 patients had T3-T4 tumor and 1 patient had T1-T2 tumor. CONCLUSION: Modified radical mastectomy followed by external radiation therapy is the standard treatment for male breast cancer. Hormone therapy, as an adjuvant treatment, is the first line approach in a majority of patients and chemotherapy is reserved for patients with poor prognostic factors.Item A view from far - letter from Europe.(2005-01-14) Yarnold, JohnItem A prospective study of pharyngocutaneous fistulas following total laryngectomy.(2005-01-14) Qureshi, S S; Chaturvedi, P; Pai, P S; Chaukar, D A; Deshpande, M S; Pathak, K A; D'cruz, A KPharyngocutaneous (PC) fistula is a common complication following laryngectomy. It leads to increased morbidity, delay in adjuvant treatment, prolonged hospitalization and an increase in treatment costs. Although a number of factors that result in PC fistula have been described, there is still no agreement on the most significant factors. We undertook a prospective study to critically analyze PC fistula and its association with various tumors, patient and treatment related factors. This was a prospective study that included 143 patients who underwent laryngeal surgery for squamous cell carcinoma of the larynx and pyriform sinus. Use of pectoralis major myocutaneous flap to reconstruct the neopharynx, primary disease in pyriform and extensive soft tissue infiltration were significantly associated with PC fistula. Prior treatment (radiotherapy and chemotherapy), type of closure (T closure, Y closure and vertical closure), Layers of closure (full thickness interrupted, submucosal interrupted, submucosal continuous) type of suture material (silk, vicryl ), age, sex, stage, preoperative tracheostomy, cut margin status, pre/postoperative hemoglobin and experience of surgeons did not relate significantly.Item A phase I trial of tocoferol monoglucoside in patients undergoing hemi-body radiation.(2005-01-14) Huilgol, N G; Nair, C K K; Merhotra, P; Kagiya, V TPURPOSE: To evaluate Tocoferol monoglucoside (TMG), a water soluble vit. E. in a phase I trial, as a radiation protector in those undergoing hemi-body radiation for disseminated disease. MATERIALS AND METHODS: Patients scheduled to receive modified hemi-body radiation were accrued for the study. Patients not only had disseminated skeletal disease but, were heavily pretreated Seven patients were accrued for the study. Patients received 1 and 2 gms of TMG. 30-40 minutes before hemibody radiation. A dose of 600 cGy was delivered on telecobalt equipment at mid plane. Immediate Toxicities were evaluated as well as response to pain. RESULTS: All the seven patients underwent radiation uneventfully. There was no drug related toxicity. Pain relief was adequate. CONCLUSION: Tocoferol monoglucoside an effective antioxidant with no significant acute toxicity, when administered in a dose of 1 or 2 gms per oral route. TMG being water-soluble can have global antioxidant and radio protective effects. This needs further clinical evaluation.Item Use of Rt-PCR in detecting disseminated cancer cells after incisional biopsy among oral squamous cell carcinoma patients.(2005-04-14) Ramani, Pratibha; Thomas, George; Ahmed, ShaheenPURPOSE: Tumour metastasis is the most clinically significant and enigmatic aspect of tumour behavior and is an unequivocal hallmark of malignancy. Until recent years little has been known about the transportation phase of vascular dissemination during biopsy, because of the technical difficulties in demonstrating circulating cancer cells. AIMS: This study examined whether cancer cell dissemination results from incisional biopsy in the peripheral blood by using Cytokeratin 19(CK-19) as the marker for Reverse Transcriptase-Polymerase Chain Reaction (RT-PCR). In-house recipes without utilizing kits were employed to extract genomic and total RNA to make the procedure user friendly. MATERIALS AND METHODS: The study population consisted of n=10 patients who were clinically diagnosed for oral squamous cell carcinoma and who had not undergone any previous biopsies. 5 patients who were to undergo incisional biopsies for benign conditions served as controls. 5 ml of blood aspirates were collected before and within 15 minutes after incisional biopsy. CK-19 gene and a positive control gene beta actin were isolated to confirm the primers. Using the total RNA, RT-PCR was performed for beta actin and Ck 19 gene expression. RESULTS: Rt-PCR did show any expression for the CK-19 gene. CONCLUSION: In conclusion there was no evidence of dissemination of cancer cells in our study and the patients are on a regular follow up for the past one and half years. But larger sample size should be examined to make the procedure a diagnostic tool for cancer metastasis.Item AK-2123 (Sanazol) as a radiation sensitizer in the treatment of stage III cancer cervix: initial results of an IAEA multicentre randomized trial.(2005-04-14) Dobrowsky, Werner; Huigol, Nagraj G; Jayatilake, Ranapala S; Kizilbash, Noor-I-Alam; Okkan, Sait; Kagiya, Tsutomu V; Tatsuzaki, HideoPURPOSE: AK-2123, a nitrotriazole hypoxic cell sensitizer has reportedly improved results in head and neck cancers, uterine cervical cancers and other solid tumours when added to radical radiotherapy. A prospectively randomised trial was initiated by the International Atomic Energy Agency (IAEA) evaluating AK-2123 and radiotherapy in treatment of uterine cervical cancer stage IIIA and IIIB. MATERIALS AND METHODS: A total of 333 patients were randomised between May 1995 and December 1998. Patients were randomised to either standard radical treatment (radiation therapy alone, RT) or standard radical radiotherapy and additional administration of AK-2123 (RT+AK-2123). The total dose of 45-50.8 Gy was delivered in 20 to 28 fractions over 4 to 5 1/2 weeks. The dose to the central disease was escalated to a radiobiologically equivalent dose of 70 Gy by external beam or brachytherapy, in accordance with each centres individual practice. In the study arm, patients received 0.6 g/sqm AK-2123 by intravenous administration before external beam radiotherapy, treating with AK-2123 on alternate days (e.g. Monday-Wednesday-Friday) during the entire course of external beam therapy. RESULTS: After a median follow up of 57 months (range 30-73 months) the rate of local tumour control was significantly higher in the group who received radiotherapy and additional administration of AK-2123. Local tumour control at the last follow up was 61% after combined radiotherapy and AK-2123 and 46% after radiotherapy alone (p = 0.005). AK-2123 neither increased gastro-intestinal toxicity nor gave any haematological toxicity. A mild peripheral neuropathy (Grade 1:11% and Grade 2:3%) was seen infrequently after AK-2123 administration and was usually completely reversible. Crude survival rates were 41% after radical treatment compared to 57% after combined therapy (p = 0.007). CONCLUSION: We conclude that the addition of AK-2123 to radical radiotherapy significantly increases response rates and local tumour control in advanced squamous cell cancer of the uterine cervix without any increase in major toxicity. Further analysis and follow up are needed to evaluate if this benefit will translate into prolonged survival. We strongly suggest that our initially very promising study should lead other centres to further studies of AK-2123 in randomised clinical trials.Item Custom-made nipple prosthesis: a long-term satisfaction survey.(2005-04-14) Janes, SimonBACKGROUND: Nipple-areola reconstruction or prosthesis completes the process of breast reconstruction. Although custom made nipple prosthesis (CNP) have been used for almost 10 years, little follow-up data on patient satisfaction is available. We assessed long-term patient satisfaction with CNP. MATERIALS AND METHODS: All patients undergoing CNP from 2000 to 2001 were sent anonymous postal questionnaires. Perceived benefit and satisfaction with size, colour, and projection, were assessed using a modified Likart scale (1 not satisfied, 5 very satisfied). Results are expressed as median and interquartile range (IQR). RESULTS: Of 52 patients who had CNP, 29 responded to the questionnaire (56% response rate), median age (IQR) 56.1 years (52-61). The median time since CNP was 2 years (0.6-3), 67% felt they had benefited from the prosthesis and 39% wore their CNP regularly. Most patients were highly satisfied with CNP size, colour and projection, median score 5 (4-5) for each variable. Patients with CNP Patients with CNP < 3 years were more likely to be satisfied with CNP than those with CNP for = 3 years, 60% vs 18%, p = 0.04. Patients who were satisfied with their CNP (median age 52.9 years, IQR 45.3-59.2 years), were younger than patients not satisfied with their CNP (median age 59 years, IQR 54.7-62 years), p = 0.031, Z = -2.16. Three patients had subsequent nipple reconstruction, a further 7 (24%) wanted nipple reconstruction. All respondents thought CNP should be offered at the time of initial surgery. CONCLUSIONS: Most patients are highly satisfied with CNP, with highest satisfaction in the first 3 years after CNP. CNP should be offered at the time of initial surgery.Item Brachytherapy--perspectives in evolution: take it with a bag of salt...(2005-04-14) Shrivastava, ShyamItem Magnetic resonance imaging in carcinoma cervix--does it have a prognostic relevance.(2005-04-14) Sethi, Tejinder Kataria; Bhalla, N K; Jena, A N; Rawat, S; Oberoi, RPURPOSE: To evaluate the prognostic relevance of tumor size as determined on Magnetic Resonance Imaging (MRI) in cervical cancer. METHODS AND MATERIALS: A total of 70 consecutive patients were included in the study. 15 patients underwent surgery alone (Group A), 27 patients underwent surgery followed by adjuvant radiation (Group B), 14 patients underwent concomitant chemo radiation (Group C), and 14 patients underwent radical radiation alone (Group D). External radiation was delivered followed by intra cavitary brachytherapy. Serial MRI scans were performed in all patients before and after completion of treatment on a 1.0 Tesla MRI scanner. Patients were divided into three groups based upon MR volumes 100 cc. A correlation between MR volume, FIGO stage, disease free survival (DFS) and overall survival (OS) was done. Disease free and overall survivals were calculated using Kaplan Meier survival curves according to stage, MR volume and treatment protocol. RESULTS: In group I (MR volume 100 cc), 57% patients had stage II, 14% had stage III and 29% patients had stage IV disease. The DFS and OS did not achieve a level of statistical significance when evaluated as per protocol [DFS at p = 0.0685 and OS p = 0.3242], however a statistical significance was seen when DFS and OS were evaluated according to MR volumes [DFS, p = 0.0015 and OS, p = 0.0001]. CONCLUSION: In cervical cancer, the volume of disease as assessed on MRI may be a better prognostic indicator than FIGO staging and needs further evaluation.Item Dose uniformity assessment of intraluminal brachytherapy using HDR 192Ir stepping source.(2005-04-14) Patel, Narayan Prasad; Majumdar, Bishnu; Hota, Pradeep K; Singh, DayanidhiPURPOSE: The aim of this study is to achieve dose uniformity for intraluminal implants by assessment of dose distributions for single catheter generated by using various combinations of source stopping spacing and optimization mode. MATERIALS AND METHODS: A dose distribution was generated using HDR 192Ir stepping source on single straight catheter of fixed length used for Intraluminal brachytherapy. The various combinations of source position spacing and optimization mode were used and these dose distributions were evaluated by using three different parameters. The source position spacings were 0.2, 0.5, 1.0, 1.4, 2.0, 2.5, 3.0 and 3.3 cm. Three different optimization modes that compute the source stopping times along the catheter were used. The parameters used for assessment of dose distributions were statistical analysis of doses to dose reference points, area under natural dose-volume histogram and the dose non-uniformity ratio. RESULTS: None of the combinations of source position spacing and optimization mode was able to generate the desired optimum uniform dose distribution. However in a discrete manner, comparatively higher uniform dose distribution was found with short (0.2 cm) and longer (1.5 to 2.0 cm) source spacing. Optimization mode of Iterative correction was found to be suitable for the single catheter used in intraluminal brachytherapy. CONCLUSION: The applicator dimension and irradiation target volume should be taken in to consideration while selecting either higher or smaller source position spacing for the single catheter intraluminal brachytherapy. The Anisotropy factor of the source has some role in the variation of the dose uniformity over the target volume.Item Fighting cancer is half the battle... living life is the other half.(2005-04-14) Pahwa, Manasi; Babu, Nandita; Bhatnagar, SushmaPURPOSE: The purpose of this study was to explore the psychological and social problems the terminally ill are facing in India. Another objective of this study was to explore the Locus of Control and Depression. AIMS: The study was conducted on an incidentally available sample of fifteen terminally ill patients at the Pain Clinic, I.R.C.H., AIIMS, ranging from young adults (30-35 years), to middle aged (40-50 years), to the elderly (55-65 years). MATERIALS AND METHODS: A thematic and narrative analysis was done using semi-structured interview. After the semi-structured interview, two standardized inventories were administered. The two inventories used were Multidimensional Health Locus of Control, and Beck's Depression Inventory. The statements from the two inventories were translated into Hindi and then asked. The inventories were not given as a questionnaire to be filled; rather they were asked orally and marked by the investigator. RESULTS: The co-relation between Internal Health Locus of Control and Depression was found to be significant below the 0.05 level. Statistics also revealed that a large number of participants were either severely depressed (33.33%) or extremely depressed (20%). The seven common themes running through all the narratives were identified; Concern for physical pain; Anxiety and Depression; Body-image problems; Social withdrawal; Disease viewed as bad 'karma'; Desire for hastened death; and lastly Hope. CONCLUSION: This article would create greater awareness among all the concerned people working with cancer patients on what intervention strategies should be utilized to help the patients, as well as, how the belief in karma can help gain a more positivistic outlook towards death and the core role spirituality and the belief in karma can play in the counseling of the patients and their families.
