    Assessing the histopathology reports of colorectal carcinoma surgery: An audit of three years with emphasis on lymph node yield
    (Wolters Kluwer - Medknow, 2022-04) Sarkar, Sourav; Deodhar, Kedar K.; Budukh, Atul; Bal, Munita M.; Ramadwar, Mukta
    Background: A comprehensive histopathology report of colorectal carcinoma surgery is important in cancer staging and planning adjuvant treatment. Our aim was to review histopathology reports of operated specimens of colorectal carcinoma in our institution between 2013 and 2015 to assess different histological parameters, including lymph node yield, and to evaluate compliance to minimum data sets. Methods: After approval by the institutional review board (IRB), we analyzed 1230 histopathology reports of colorectal carcinoma between 2013 and 2015. Various gross and microscopic findings (along with age, sex) were noted, for example, specimen type, tumor site, resection margins including circumferential resection margin (CRM), lymphovascular invasion, perineural invasion, pTNM stage, lymph node yield, etc. Results: Out of 1230 patients, 826 (67.15%) were men and 404 (32.85%) were women. The overall mean age was 52 (range: 18 - 90) years. There were 787 surgeries for rectal cancers. All reports commented on the type of specimen, tumor size (mean = 4.38 cm), proximal, and distal margins. Lymphovascular invasion (LVI) and the pT stage were mentioned in 98.06% and 99.84%, respectively. The overall mean lymph node yield was 18.38 (median = 15, range = 0-130 lymph nodes). A statistically significant difference in lymph node yield was detected between rectal and colonic cancer patients (14.79 and 27.26); post neoadjuvant therapy (NACT) cases, and NACT naive cases (13.51 and 25.11); and high tumor stage and low tumor stage disease (20.60 and 15.22). Not commenting on extramural vascular emboli, tumor budding, and CRM in non-rectal cancer cases were the lacunae. Conclusion: Our compliance with minimal data sets is satisfactory. The overall mean lymph node yield was 18.38 (median = 15). Extramural vascular emboli, tumor budding need to be captured.

    Endometrial serous carcinoma: A retrospective review of histological features & their clinicopathological association with disease-free survival & overall survival
    (Wolters Kluwer – Medknow, 2022-07) Agarwal, Arti; Yadav, Subhash; Dusane, Rohit; Menon, Santosh; Rekhi, Bharat; Deodhar, Kedar K.
    Background & objectives: Endometrial serous carcinoma (ESC) is a high-grade epithelial neoplasm with increased risk for metastasis and recurrence. This study was aimed to assess various histomorphological features of ESC and their clinicopathological association with disease-free survival (DFS) and overall survival (OS). Methods: A total of 205 slides (belonging to 120 patients) diagnosed as ESC from January 2009 to December 2015 were reviewed. Receiver operating characteristics (ROC) curves were established for the diagnostic performance of depth of invasion (DOI), tumour-free distance (TFD) to serosa and percentage myometrial invasion (MI%). OS and DFS were generated by Kaplan-Meier curves and prognostic significance by Cox regression analysis. Results: The mean age at diagnosis was 61.8 yr and the mean tumour size was 4.01 cm. Majority of the females were multiparous (84%; n=94) and postmenopausal (89.2%; n=107). On histopathology, <50 per cent of MI was identified in 37 of the 104 (35%), while 62/104 (59.61%) patients had ?50 per cent MI. Seven (6.7%) patients had full-thickness invasion with serosal involvement, while five (4.8%) patients had no microscopic MI (minimal uterine serous carcinoma). Information about MI was not available in 16 patients. TFD ?7.0 mm, DOI ?6.0 mm and MI% ?40 were significant variables in univariate analyses for OS; however, on multivariate analysis; none of these turned out to be an independent predictor in terms of OS. For DFS, DOI (?6.0 mm) and MI% (?40%) showed a significant association, in univariate as well as multivariate analysis; however, TFD (?7.0 mm) did not show any significant association with DFS. Follow up data were available in 111 of the 120 (92.5%) patients with a five-year OS and DFS of 22.2 and 17.2 per cent, respectively. Interpretation & conclusions: Conventionally calculated DOI (less than or more than half thickness) did not show significance in the present study. Thus, calculating the actual myometrial DOI, MI% and TFD to serosa have the potential for contributing meaningfully to prognostication of ESC
