Clinical significance of CT detected enlarged cardiophrenic nodes in ovarian cancer patients
Aim To assess the relevance of enlarged cardiophrenic lymph nodes (CPLN) seen on staging CT of ovarian cancer patients. Methods Retrospective cohort study of consecutive patients with primary ovarian malignancy who underwent staging CT between 2013 and 2016. Images were reviewed by two radiologists in consensus. Enlarged CPLN was defined as a short axis diameter ≥ 7 mm. Clinical and imaging findings; management decisions; outcome of cytoreductive surgery and survival were compared between patients with and without enlarged CPLN on staging CT. Results Enlarged CPLN were found in 42 patients (41.5%) and was significantly associated with higher radiological PCI ( p  = 0.002); large volume upper abdominal disease ( p  = 0.001); enlarged lesser omental, periportal and supra-renal para-aortic lymph nodes ( p  ≤ 0.05); unfavorable sites of disease involvement ( p  < 0.001) and extraperitoneal metastases ( p  = 0.004). While there was a significant difference in the number of patients who underwent primary and interval debulking ( p  = 0.002), there was no difference in the rates of optimal cytoreduction between the two groups ( p  = 0.469). After adjusting for outcomes of cytoreductive surgery, CT detected enlarged CPLN did not adversely affect the overall survival, HR 1.5 (0.708–3.4), p  = 0.272, but adversely affected the recurrence free survival (HR 2.38 (1.25–4.53)), p  = 0.008. Conclusions Enlarged CPLN detected on staging CT in patients with primary ovarian cancer is clinically significant even in the developing world and is associated with higher volume of peritoneal, non-regional nodal and extraperitoneal disease and lower recurrence free survival.
Role of squamous cell carcinoma antigen in prognostication, monitoring of treatment response, and surveillance of locally advanced cervical carcinoma
ABSTRACT Introduction: Squamous cell carcinoma antigen (SCC Ag) is a sub-fraction of the tumor antigen TA-4, first isolated by Kato and Torigoe, the most commonly used tumor marker in cervical cancer. It can be used as a serum marker to detect residual disease, early local recurrence, or distant metastasis in locally advanced cervical cancer even before the clinical symptoms of recurrence or metastasis. Methods and Materials: Between January 2018 and August 2018, 30 patients with squamous cell carcinoma cervix (FIGO) stages IB2-IVA, who received concurrent chemoradiation, followed by brachytherapy, were included in the study. Serum SCC Ag levels were collected at four time points during the course of the treatment, and their correlation with tumor and treatment factors were analyzed. Results: As the FIGO stage increases, mean pre-treatment SCC Ag also increases. Node-positive patients had higher pre-treatment SCC Ag as compared to those who were negative (P = 0.05). There was a statistically significant decreasing trend in the mean SCC Ag at the end of EBRT (P = 0.015). After completion of treatment, 78% had a complete response, 8% had a partial response, and 14% had progressive disease with statistically significant elevation of SCC Ag at 6 weeks of follow-up (P = 0.01). Patients who progressed or had the residual disease at follow-up were found to have high pre-treatment SCC Ag values. Conclusion: SCC Ag can be potentially used as a reference indicator of biological behavior of cervical cancer, to monitor the treatment response, and as a prognostic marker, especially in those with node-positive disease.
Diagnosis and management of 5-fluorouracil -induced acute leukoencephalopathy: lessons learnt from a single-Centre case series
Background The administration of 5-fluorouracil (5FU) in the treatment of gastrointestinal (GI) malignancies is associated with common side effects such as mucositis, diarrhoea, and myelosuppression, which are easily managed with supportive measures and dose adjustments. Cardiotoxicity and neurotoxicity are rare but reversible side effects of 5-FU and are treated with withdrawal of the drug and conservative measures. The presenting symptoms of 5-FU-induced leukoencephalopathy are often confusing and pose a diagnostic dilemma in routine clinical practice. Methods We report a series of five patients with GI malignancies who developed 5-FU-induced leukoencephalopathy. Results All (n = 5) had Naranjo scores of 6-7, predictive of 5-FU-related adverse effects, with clinical and radiological findings suggestive of 5-FU-induced encephalopathy as described in prior literature. The median time to onset of symptoms from initiation of 5FU was 3 days (range: 2-4 days). All patients improved after conservative management with complete neurological recovery. Conclusion Prompt recognition of this rare yet severe adverse effect of 5-FU-based chemotherapy aids early withdrawal of the offending agent (5-FU) and timely initiation of supportive measures and helps plan alternative oncological interventions.
Is There Any Difference in Stem Cell Population between Type I and Type II Endometrial Cancer? A Pilot Study
The incidence of endometrial cancer is increasing globally. Cancer stem cells are now considered the driving force for tumour recurrence and metastasis. We studied whether the proportion of cancer stem cell population and stemness gene expression differ in type I and type II endometrial cancer. Type I and type II endometrial tumour tissues were obtained from patients who underwent hysterectomy. The tumour tissue was digested using collagenase, and we established a primary culture. In the primary cultures established from these two types of cancer, we used flow cytometry to measure the proportion of the cancer stem cell population expressing CD 133 and CXCR4 on its surface. We also looked for the expression of genes related to stemness, regulators of stemness, and markers of metastasis in both these cancer types. We found that the proportion of cancer stem cell population that expresses CD133 and CXCR4 was higher in type II endometrial cancer than in type I endometrial cancer. Also, genes (Nanog, ALDH, EZH2) related to stemness and aberrant transcriptome were found to be upregulated in type II endometrial cancer. Our study demonstrates that the proportion of stem cells in type 2 endometrial cancer is higher than in type I endometrial cancer. The findings of this study should lead us to investigate with a larger sample size and see if the increase in the stem cell population in type II endometrial cancer may be the reason for its poor prognosis.
Haemostatic radiation therapy for a bleeding intraductal papillary neoplasm of the biliary tree
Haemostatic radiation was effectively used as a novel rescue therapy in a 60-year-old man who presented with recurrent melaena refractory to all conventional medical and surgical measures. He needed multiple transfusions and was diagnosed to be bleeding from an intraductal papillary biliary neoplasm which was not amenable to surgical resection in view of the background liver disease. He received conventional radiation therapy (RT) of a dose of 3 Gy per fraction for 3 consecutive days after which he stabilised. After cessation of the RT, he did not require transfusion for the next 2 months. His quality of life improved and it gave us time to evaluate for other definitive measures.
Analysis of patients with endometrial carcinoma using the ProMise classifier: a pilot study from India
Background Molecular subtyping of endometrial carcinomas (EC) has been shown to classify tumors into prognostically relevant groups. Characterizing EC with a limited number of markers viz., POLE mutations, p53 mutations, and MMR status, can provide valuable information. Design Paraffin sections of a cohort of 48 EC from a tertiary care center were characterized for the above-mentioned molecular markers and analyzed in the context of survival. Methods Formalin fixed paraffin embedded tissues from 48 EC were characterized for POLE mutations by Sanger sequencing (exons 9–14), for MMR (MLH1, MH2, MSH6) using immunohistochemistry (IHC) and copy number (high/low) using p53 IHC. Mutational status was integrated along with the clinicopathological details and survival analysis performed. Results Eleven (22.9%) patients were MMR deficient, 3 (6.3%) had POLE mutation, while 2 (4.1%) had both POLE and P53 mutations (regarded as multiple classifiers). Twelve (25%) patients were found to have P53 mutations, while the remaining 20 (41.7%) had no specific molecular profile (NSMP). Median follow-up duration was 43.5 (2–62) months with 8 recurrences and 9 deaths. Tumors with POLE mutation had the most favorable prognosis followed by the NSMP and the MMR mutated group while the P53 and multiple classifier groups had the worst prognosis in terms of OS (Log-rank p : 0.006) and PFS (Log-rank p : 0.001). Conclusion The integration of molecular-clinicopathologic data for endometrial cancer classification, through cost-effective, clinically applicable assays appears to be a highly objective tool that can be adopted even in resource-limited settings. It has the potential to cause a shift in the paradigm of EC pathology and management practice.
Paraneoplastic Pemphigus Associated with Follicular Dendritic Cell Tumor in the Mediastinum
Paraneoplastic Pemphigus (PNP) is an autoimmune bullous disease characterized by severe stomatitis, polymorphous skin eruptions, and underlying neoplasms. Diagnosis of cutaneous paraneoplastic disorders requires high index of suspicion. We describe a patient with PNP associated with follicular dendritic cell (FDC) tumor in the mediastinum, a rare neoplasm originating from follicular dendritic cells. Its management requires identification of underlying malignancy and treatment of the same. Our patient showed remission of PNP upon excision of the tumor and remained disease-free for 8 years.
Strategies for primary HPV test-based cervical cancer screening programme in resource-limited settings in India: Results from a quasi-experimental pragmatic implementation trial
In order for low and middle income countries (LMIC) to transition to Human Papilloma Virus (HPV) test based cervical cancer screening, a greater understanding of how to implement these evidence based interventions (EBI) among vulnerable populations is needed. This paper documents outcomes of an implementation research on HPV screening among women from tribal, rural, urban slum settings in India. A mixed-method, pragmatic, quasi-experimental trial design was used. HPV screening on self-collected cervical samples was offered to women aged 30-60 years. Implementation strategies were 1) Assessment of contextual factors using both qualitative and quantitative methods like key informant interviews (KII), focus group discussions (FGDs), pre-post population sample surveys, capacity assessment of participating departments 2) enhancing provider capacity through training workshops, access to HPV testing facility, colposcopy, thermal ablation/cryotherapy at the primary health care centers 3) community engagement, counselling for self-sampling and triage process by frontline health care workers (HCWs). Outcomes were assessed using the RE-AIM (Reach, Effectiveness, adoption, implementation, maintenance) framework. Screening rate in 8 months' of study was 31.0%, 26.7%, 32.9%, prevalence of oncogenic HPV was 12.1%, 3.1%, 5.5%, compliance to triage was 53.6%, 45.5%, 84.6% in tribal, urban slum, rural sites respectively. Pre-cancer among triage compliant HPV positive women was 13.6% in tribal, 4% in rural and 0% among urban slum women. Unique challenges faced in the tribal setting led to programme adaptations like increasing honoraria of community health workers for late-evening work and recalling HPV positive women for colposcopy by nurses, thermal ablation by gynaecologist at the outreach camp site. Self-collection of samples combined with HCW led community engagement activities, flexible triage processes and strengthening of health system showed an acceptable screening rate and better compliance to triage, highlighting the importance of identifying the barriers and developing strategies suitable for the setting.
