(Association of Physicians of India, 2022-05) Bhandari, Sudhir; Rankawat, Govind; Mathur, Sandeep; Kumar, Anshul; Sahlot, Rahul; Jain, Avinash
Objectives: Neuroborreliosis is generally known to be a disease confined to the Western part of the globe. It is not commonly encountered in this part of the world. Interestingly, we recently came across a series of cases of Lyme’s disease with a plethora of neurological presentations. Most of the cases were a diagnostic dilemma, with poor response to immunotherapy and on subsequent evaluation all were found to have positive Borrelia antibodies. Materials and methods: Eight cases were selected from the tertiary care hospital in North western India. Patients were suspected to have Neuroborreliosis whose neurological presentations were atypical for other classical neurological disorders, who had a progressive or relapsing clinical course and had responded poorly to the initial treatment given for the previous neurological diagnosis. Skin lesions were present in some cases. The patients underwent a detailed clinical assessment which comprised of an elaborate history including history of travel, any insect bite or skin rashes along with a complete systemic and neurological examination. All the required blood investigations, Magnetic Resonance Imaging (MRI) Brain, Computer Tomography Angiography (CT), Nerve conduction study (NCS) and Electromyographic (EMG) studies and Cerebrospinal fluid (CSF) studies were done as indicated in each case. Borrelia antibody titre was done in all the patients using immunoblot technique. Results: Among the 8 patients, 6 were male and 2 were females. The age group was between 25-70 years. The clinical presentation was acute, subacute or chronic. One patient gave a clear history of tick bite. Two patients had skin lesions and one had the pathognomic "eschar". All the suspected 8 patients had either IgG or IgM or both IgG and IgM Borrelia antibodies positive. Almost all the patients had previously received either steroids or intravenous immunoglobulins, but had not adequately responded to immunotherapy. These patients were given a trial of injectable Ceftriaxone and oral Doxycycline. Most of them either showed partial or complete clinical improvement. Conclusion: Lyme’s disease, a common disease of the west does exist in the Indian subcontinent as well. Because of increasing global travel and migration and change in vector habitat the disease seems to have percolated in the non endemic areas too. Proper history of travel or exposure to tick bite is important. We want to emphasize, Neuroborreliosis, a great mimicker may have diverse and varied neurological presentations and has a potential for reversibility with appropriate treatment even after a significant delay in diagnosis.

(Indian Cancer Society, 2018-10) Gogia, Ajay; Raina, Vinod; Deo, Surya Vansham Suryanarayan; Shukla, Nootan Kumar; Mathur, Sandeep; Mohanti, Bidhu Kalyan; Sharma, Daya Nand
BACKGROUND: Invasive lobular carcinoma (ILC) is the second most common histologic subtype of breast cancer and accounts for 10%–15% of all breast cancers in the west. There is a scarcity of data on ILC from the Indian subcontinent. This report intends to present the patterns of care, survival outcomes, and prognostic factors of ILC treated in a tertiary care institute. MATERIALS AND METHODS: This retrospective analysis included consecutive patients diagnosed with ILC and registered at our Institute between 2009 and 2016. RESULTS: We included 97 patients with a median age of 53 years (range 28–80). American Joint Committee on Cancer (7th edition) stage distribution was stage I-8.24%, stage II-45.36%, stage III- 34.10%, and stage IV-12.30%. Bilateral breast cancer was seen in 8 cases. Estrogen receptor, progesterone receptor, and HER 2/neu positivity was 90%, 85%, and 9%, respectively. Triple-negative breast cancer constituted 5% of cases. Twenty-nine events were recorded (systemic and locoregional relapse) with a median follow-up of 3.5 years. Three years relapse-free survival (RFS) and overall survival were 80% and 60%, respectively. Bones were the most common site of metastasis. Age <45 years [HR-1.4 (0.8–2.1), P < 0.001] and advanced clinical tumor stage [T4, HR-2.1 (1.1–3.8), P = 0.001] were associated with poor RFS. CONCLUSION: ILC constituted 2.5% of breast cancer cases at our institute. Triple negativity and HER-2/neu positivity were seen in 9% and 5% of cases, respectively. Age <45 years and advanced clinical tumor stage were associated with poor RFS.

(Indian Cancer Society, 2018-07) Gogia, Ajay; Deo, S VS; NK, Shukla; Mathur, Sandeep; Sharma, DN; Tiwari, Akash
INTRODUCTION: This study was undertaken to evaluate the clinicopathological characteristics of patients with breast cancer at our institute, a tertiary-care cancer center in northern India. MATERIALS AND METHODS: This retrospective study included all patients with breast cancer registered at our institute from January 1st, 2014 to December 31st, 2016. We retrieved data (demographic, baseline clinical characteristics, pathology, and treatment details) from prospectively maintained clinical case records. Patients with incomplete case records or missing baseline information were excluded. RESULTS: We included 550 patients with breast cancer. The median age was 48 years (23–85). The median clinical tumor size was 5.0 cm. The TNM (AJCC-7th edition) stage distribution was stage I, 22 (4%); stage II, 182 (33%); stage III, 247 (44.9%); and stage IV, 99 (18%). Locally advanced breast cancer constituted 40% of the cases. Bone (48 [48.5%]) was the most common site for metastasis followed by lung. Infiltrating ductal carcinoma (528 [96%]) was the most common histologic subtype. Majority of patients, 325 (59%), were positive for estrogen receptor/progesterone receptor whereas 160 (29%) patients were HER2/neu positive. Triple negative breast cancer (TNBC) constituted 28% (154) of patients. In the nonmetastatic subgroup, 343 (76%) patients underwent modified radical mastectomy. Neoadjuvant chemotherapy (NACT) was given in 120 (26.6%) patients, of these 23 (19%) achieved pathological complete remission. Sequential anthracyline and taxane were used as NACT/adjuvant chemotherapy in most cases. Of the eligible patients, 48 (30%) received anti-HER2/neu therapy. CONCLUSION: This is one of the largest comprehensive data from a single center in India. Majority of our patients are younger in age and have advanced disease. TNBC and HER2/neu positive breast cancer are more common in our population.
Comparison of resection margins and cosmetic outcome following intraoperative ultrasound-guided excision versus conventional palpation-guided breast conservation surgery in breast cancer: A randomized controlled trial
(Indian Cancer Society, 2018-10) Vispute, Tejas; Suhani; Seenu, V; Parshad, Rajinder; Hari, Smriti; Thulkar, Sanjay; Mathur, Sandeep
INTRODUCTION: Use of intraoperative ultrasound (IOUS) has been shown to help achieve satisfactory cosmesis and negative margins in breast conserving surgery (BCS). This study has been done to compare the oncological and cosmetic outcomes following BCS using conventional palpatory method and IOUS. MATERIALS AND METHODS: This is a prospective randomized controlled trial conducted at a tertiary care teaching and research institute in India. Patients with early operable breast cancer willing for BCS were included. Tumors were excised with 1 cm margin. In palpatory group, tumor was palpated and 1 cm margin was taken with a measuring scale while in the second group, IOUS was used to mark the margins. Histopathological evaluation was done to assess margins and cosmesis was assessed by patient, resident doctor, and nurse independently. RESULTS: Sixty patients were included, 32 in the ultrasonography-guided and 28 in palpation-guided wide local excision. The mean age of patients was 48.78 years. In both groups, mean tumor size was 3.18 cm. Margin thickness and positivity was higher in palpatory group (though P > 0.05). Most patients were satisfied with cosmesis. There was no significant difference in complications and specimen volume in both groups. Presence of ductal carcinoma in situ component and expression of Her2neu by tumor cells had a significant impact on margin positivity. CONCLUSIONS: Intraoperative use of ultrasound offers a real-time assessment of margin status and may reduce the margin positivity rate compared to conventional palpation-guided method.
Diagnosis and grading of non-Hodgkin's lymphomas on fine needle aspiration cytology.
(2007-01-04) Mathur, Sandeep; Dawar, Ramesh; Verma, Kusum
Fine needle aspiration cytology (FNAC) enjoys popularity among clinicians worldwide, as a first line of investigation in all patients with lymphadenopathy and is preferred over biopsy because of its minimally invasive nature and cost-effectiveness. Although non-Hodgkin's lymphomas (NHL) are conventionally diagnosed and graded on biopsy specimens, it may be useful to be able to not only diagnose but also grade these cases on FNAC smears. The WHO and REAL classifications forming the basis of treatment in some centres rely on clinical features, immunocytochemistry and cytogenetics, which are beyond reach of most centres in the developing countries. This study therefore is aimed at diagnosing and grading NHLs on morphological parameters. The cytologic grading accuracy is compared with the histologic grades assigned according to the International Working Formulation (IWF) system which relies solely on morphological features, most important of which is cell size. Ninety five cases were retrieved over a 3 year period (May 2000 to April 2003). These were (i) cases where a cytological diagnosis of NHL or suspicious of NHL was made and corresponding histological sections available and (ii) cases where a diagnosis of NHL was made in histology and corresponding FNAC smears were available irrespective of the cytological diagnosis. The diagnostic accuracy of FNAC for NHLs was determined using histology as the gold standard. Cases were also graded on FNAC smears using a three tier grading system based upon cell size into low, intermediate and high grades. Cytologically assigned grades were correlated with the corresponding histological grades (IWF) to determine grading accuracy. An accurate diagnosis of NHL was thus possible in 67/95 (70.5%) cases. Overall accurate grading was seen in 65/95 (68%) cases using cytological criteria. Accurate cytologic grading was possible in 14/15 (93.33%) low grade, 11/18 (61.11%) intermediate and 40/62 (64.5%) high grade non Hodgkin's lymphomas. Kappa statistics revealed a very good agreement between cytological and histological grades for low grade NHL. The kappa scores for intermediate and high grade NHLs indicated moderate agreement. Using the two-tier system grading the kappa value for high grade lymphomas improved to 0.72, indicating good concordance. This study highlights the utility of FNAC as a morphological tool for diagnosing and grading NHLs in a significant number of cases. This modality may assist clinicians in management of cases of NHLs, especially in centres working within the constraints of limited availability or non availability of ancillary techniques.
Functional adrenal oncocytoma: a rare neoplasm.
(2008-10-15) Sharma, Nitin; Dogra, Prem Nath; Mathur, Sandeep
Adrenal oncocytoma is a rare adrenal neoplasm with only 21 cases reported in English literature. These adrenal tumors are usually nonfunctional and hence incidentally detected. Most of these adrenal neoplasms are benign. We report a rare case of adrenal oncocytoma that was functional and was successfully managed by laparoscopic adrenalectomy.
Image guided versus palpation guided core needle biopsy of palpable breast masses: a prospective study.
(2016-05) Hari, Smriti; Kumari, Swati; Srivastava, Anurag; Thulkar, Sanjay; Mathur, Sandeep; Veedu, Prasad Thotton
Background & objectives: Biopsy of palpable breast masses can be performed manually by palpation guidance or under imaging guidance. Based on retrospective studies, image guided biopsy is considered more accurate than palpation guided breast biopsy; however, these techniques have not been compared prospectively. We conducted this prospective study to verify the superiority and determine the size of beneficial effect of image guided biopsy over palpation guided biopsy. Methods: Over a period of 18 months, 36 patients each with palpable breast masses were randomized into palpation guided and image guided breast biopsy arms. Ultrasound was used for image guidance in 33 patients and mammographic (stereotactic) guidance in three patients. All biopsies were performed using 14 gauge automated core biopsy needles. Inconclusive, suspicious or imaging-histologic discordant biopsies were repeated. Results: Malignancy was found in 30 of 36 women in palpation guided biopsy arm and 27 of 36 women in image guided biopsy arm. Palpation guided biopsy had sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of 46.7, 100, 100, 27.3 per cent, respectively, for diagnosing breast cancer. Nineteen of 36 women (52.8%) required repeat biopsy because of inadequate samples (7 of 19), suspicious findings (2 of 19) or imaging-histologic discordance (10 of 19). On repeat biopsy, malignancy was found in all cases of imaging-histologic discordance. Image guided biopsy had 96.3 per cent sensitivity and 100 per cent specificity. There was no case of inadequate sample or imaging-histologic discordance with image guided biopsy. Interpretation & conclusions: Our results showed that in palpable breast masses, image guided biopsy was superior to palpation guided biopsy in terms of sensitivity, false negative rate and repeat biopsy rates.

(Wolters Kluwer India Pvt. Ltd., 2019-12) Benson, Rony; Pathy, Sushmita; Kumar, Lalit; Mathur, Sandeep; Dadhwal, Vatsla; Mohanti, Bidhu Kalyan
Aim: The survival in locally advanced cervical cancer remains low. We evaluated the role of neoadjuvant chemotherapy (NACT), chemoradiotherapy (CRT), followed by gefitinib maintenance in locally advanced cervical cancer. Materials and Methods: Twenty-five patients with locally advanced carcinoma cervix were enrolled between July 2012 and May 2013. Patients received 6 weekly doses of NACT Paclitaxel (60 mg/m2) and carboplatin (AUC 2), followed by CRT and brachytherapy. The analysis of epidermal growth factor receptor (EGFR) expression was carried out by immunohistochemistry. Gefitinib (250 mg daily) was given as maintenance therapy for 1 year after completion of chemoradiation. Comparison of EGFR expression and survival outcomes was done. Results: Twenty-four of 25 patients completed the neoadjuvant chemotherapy and concurrent chemoradiotherapy. Post-CRT, all patients were started on gefitinib maintenance, and twenty patients completed the intended 1 year of gefitinib maintenance. Nineteen (76%) patients had a radiological complete response to NACT. EGFR was moderately or strongly expressed in 86.3% of the patients. The 3-year overall survival was 69.8%, and 3-year progression-free survival was 51.4%. Expression of EGFR was not found to be a significant factor affecting overall survival or progression-free survival. Conclusions: Weekly neoadjuvant chemotherapy is associated with a good response rate in locally advanced cervical cancer. Neoadjuvant chemotherapy, chemoradiation, followed by gefitinib maintenance gives good survival outcome in patients with locally advanced cervical cancer.
Optimization of sentinel lymph node identification techniques in the Indian setting: A randomized clinical trial
(Indian Cancer Society, 2019-04) V, Seenu; Suhani, Suhani; Srivastava, Anurag; Parshad, Rajinder; Mathur, Sandeep; Kumar, Rakesh
INTRODUCTION: The recommended technique of sentinel lymph node biopsy (SLNB) in breast cancer is a combination of blue dye and radiotracer. In the Indian scenario, SLNB is still not routinely practiced due to lack of nuclear medicine facilities and unavailability of isosulfan blue or patent blue violet (PBV). This study was conducted for optimizing SLN identification techniques by comparing the identification rate using PBV and methylene blue (MB) in combination with radiotracer. MATERIALS AND METHODS: Single-blinded two-arm parallel design randomized control trial was conducted at an apex teaching and research medical institute in India. Patients with axillary LN–negative breast cancer were included. Blue dye and radio tracer were injected preoperatively, and SLNB was performed using a combination technique. Frozen section was performed. Demographic, clinical, radiological, operative, and histopathological data were recorded. Descriptive statistics were used to represent patient characteristics. Baseline characteristics for entire cohort and between groups were compared using Student's t-test for quantitative variables and Chi-square test for qualitative variables. RESULTS: A total of 119 patients were randomized for mapping with MB and 118 patients with PBV between 2011 and 2015. SLN was identified in 116 patients with MB and 115 with PBV. SLN identification proportions were 97.4% (MB) and 96.6% (PBV). In patients undergoing axillary lymph node dissection, concordance with SLNB was 98.5% and 96.61% in MB and PBV, respectively. False-negative proportion for MB was 2.56% and 7.69% for PBV, respectively. The cost of MB is about INR 15 per ~10-mL vial. The cost of PBV is approximately ~$91 per ampoule (equivalent to approximately INR 8190). CONCLUSION: SLNB using MB can be recommended as the technique of choice in low-resource settings.
Peritoneal metastasis in Stage IB1 adenocarcinoma cervix: A rare entity
(Wolters Kluwer India Pvt. Ltd., 2019-12) Singhal, Seema; Kumar, Sunesh; Sharma, Dayanand N; Mathur, Sandeep
The presence of ovarian or peritoneal metastasis in early-stage cervical malignancy is a rare entity. It often poses a diagnostic challenge whether it is a synchronous primary tumor or a metastatic lesion. A 63-year-old postmenopausal woman presented with Stage 1B1 carcinoma cervix with ascites, and a 5.8 cm × 4.2 cm × 3.5 cm left solid adnexal mass. She underwent Type III radical hysterectomy, excision of peritoneal mass, with bilateral pelvic and paraaortic lymphadenectomy and infracolic omentectomy. On histopathology, cervix showed features of adenocarcinoma, and the peritoneal mass revealed similar histomorphology as cervical growth with metastatic tumor deposits in omentum. Immunohistochemistry (IHC) was utilized to determine the origin of mass. The early stage disease and histology may not always predict the distant metastasis. Therefore, a thorough pretreatment evaluation, meticulous intraoperative assessment, and IHC are mandatory for optimum management and prognostication
Primary pulmonary leiomyosarcoma of lung: An unusual entity with brief review.
(2015-07) Nath, Devajit; Arava, Sudheer; Joshi, Prashant; Madan, Karan; Mathur, Sandeep
Primary pulmonary leiomyosarcomas are rare and diagnostically challenging group of neoplasms approximately constituting 0.2-0.5% of all primary lung malignancies. They originate from the smooth muscle cells of the bronchial wall, blood vessels or from the pulmonary interstitium. Here we present a case of 45 year old male with history of chronic cough, breathlessness and chest pain for few months. Clinical and radiological workup showed a left upper lobe lung mass. Endobronchial ultrasound guided (EUS) needle biopsy of the mass on histopathology confi rmed leiomyosarcoma. Further through evaluation ruled out the possibility of metastasis. A fi nal diagnosis of primary leiomyosarcoma of lung was made and patient was planned for surgical management.
Role of pelvic and para-aortic lymphadenectomy in epithelial ovarian cancers
(Medip Academy, 2020-01) Gupta, Pankush; Kumar, Sunesh; Singhal, Seema; Meena, Jyoti; Mathur, Sandeep; Kumar, Lalit
Background: Lymphadenectomy in epithelial ovarian cancers has remained a controversial subject. Lack of robust evidence on survival benefits and surgical morbidity associated questions its role in the era of adjuvant chemotherapy. The present study assessed pelvic and para-aortic lymph node removal in epithelial ovarian cancer in Indian women and tried to find clinicopathological correlation of nodal involvement and postoperative implications of lymphadenectomy.Methods: Thirty patients with diagnosis of epithelial ovarian cancer posted for primary debulking surgery were recruited and underwent staging laparotomy along with pelvic and para-aortic lymphadenectomy. Nodal involvement was confirmed on histopathology and various parameters which could predict nodal metastasis were assessed. Patients were followed up for 12 months post-surgery.Results: Nodal yield was ten for pelvic and four for paraaortic nodes. Pelvic node involvement was seen in 26.6% (8/30) of the patients and para-aortic in 15% (3/20) of the patients. Serous histology, higher grade, stage 3 and above, positive peritoneal cytology, omental involvement showed a higher lymph node involvement though not statistically significant. Para-aortic lymphadenectomy was associated with increased operating time, blood loss and longer hospital stay.Conclusions: Lymphadenectomy increases morbidity and decision should be based on predictors of nodal involvement.
Single visit approach for management of cervical intraepithelial neoplasia by visual inspection & loop electrosurgical excision procedure.
(2012-05) Singla, Shilpa; Mathur, Sandeep; Kriplani, Alka; Agarwal, Nutan; Garg, Pradeep; Bhatla, Neerja
Background & objectives: Developing a feasible and sustainable model of cervical cancer screening in developing countries continues to be a challenge because of lack of facilities and awareness in the population and poor compliance with screening and treatment. This study was aimed to evaluate a single visit approach (SVA) for the management of cervical intraepithelial neoplasia (CIN) using visual inspection with acetic acid (VIA) and Lugol's iodine (VILI) along with loop electrosurgical excision procedure (LEEP) in women attending Gynaecology OPD in a tertiary care hospital in north India. Methods: In this hospital-based study, 450 women receiving opportunistic screening by conventional Pap cytology were also screened by VIA and VILI. VIA/VILI positive cases underwent same-day colposcopy and biopsy of all lesions. If the modified Reid score was >3, the patient underwent LEEP at the same visit. Results: Of the 450 women screened, 86 (19.1%) and 92 (20.5%) women were VIA and VILI positive, respectively. Detection rates of VIA, VILI and cytology findings at ASCUS threshold were 33.3, 35.5 and 24.4 per 1000, women, respectively to detect a lesion >CIN1. For detection of CIN2+ lesion, detection rates of VIA, VILI and cytology were 20, 22.2 and 22.2 per 1000 women, respectively. Sixteen patients with Reid score >3 underwent the See-and-treat protocol. The overtreatment rate was 12.5 per cent and the efficacy of LEEP was 81.3 per cent. There were no major complications. Interpretation & conclusions: The sensitivity of VIA/VILI was comparable to cytology. A single visit approach using visual screening methods at community level by trained paramedical personnel followed by a combination of ablative and excisional therapy can help to decrease the incidence of cervical neoplasia.
