Oral glutamine: Is there a role in the amelioration of radiation-induced mucositis? A prospective case-control study at a tertiary care centre in North India.

BACKGROUND: The most frequently occurring painful and dose-limiting side effect of radiation therapy (RT) to the head and neck region is oral mucositis (OM). Several studies demonstrated that glutamine may reduce the severity and the duration of OM significantly during RT and chemo-radiotherapy in patients with head and neck cancer (HNC). MATERIALS AND METHODS: Between January 2021 and August 2022, a prospective single institutional case-control study compared the efficacy and safety of oral glutamine on radiation-induced mucositis in patients with HNC. Of 60 biopsy-proven patients with HNC, 30 patients in the study arm received oral glutamine suspension (10 g in 500 mL of water) orally once daily, 2 hours before RT, receiving definitive or adjuvant RT and chemo-radiotherapy, while as 30 patients in the control arm received placebo with the same dose and schedule (n = 30 in the study arm and n = 30 in the control arm). RESULTS AND ANALYSIS: A total of 27 (90%) in the glutamine arm and 28 (93.33%) patients in the control arm developed mucositis. Grade 3 mucositis (13.33%) and Grade 4 mucositis (6.66%), respectively, were significantly less ( P = .040 and P = .004) in the glutamine arm. The mean duration of grade 3 and grade 4 mucositis was significantly less in the glutamine arm (8.94 days in the study arm vs. 14.54 in the control arm; P = .0001). The mean time of onset of OM was significantly delayed in the glutamine arm in comparison to the control arm with P < .001. CONCLUSION: Glutamine delays the onset of OM and decreases the severity of OM in patients of HNC receiving RT with or without chemotherapy.

Carcinoma cervix: A single institute experience from Kashmir, Northern India.

Background: Carcinoma cervix is the fourth most commonly diagnosed cancer worldwide, with an estimated 604,000 new cases and 342,000 deaths worldwide in 2020. Carcinoma cervix is an uncommon malignancy in Kashmir. In this retrospective study, we have tried to find clinicopathological characteristics of carcinoma cervix along with the survival rates at our tertiary care hospital. Materials and Methods: Case records of cervical cancer patients registered from January 1, 2015, to January 1, 2019, were retrieved. A total of 138 patients was registered. 22 had undergone surgery, and out of these 17 had received postoperative radiotherapy. 109 patients were treated with definitive chemoradiation and 13 with palliative radiotherapy. Descriptive statistics were used to summarize patient and treatment-related variables, and Kaplan-Meier analysis was performed for survival analysis. Results: A total of 138 cases that were registered from 2015 to 2019 were included in this study. The median age at the presentation was 56 years. Most of the patients had a performance status of 1 (98 patients (71.01)). Most of the patients 110 (79.71%) were married before 20 years of age, only 1 patient was unmarried, and 85 (61.59) patients were multiparous in our study group. Only 14 (10.14%) patients in our study group had a history of oral contraceptive use and most of them were non-smokers [124 (89.80%)]. Multiple marriages were present in 8 (5.79%) patients only. The most common presenting symptom was bleeding per vagina (78.26%), and the maximum number of patients fall in the post-menopausal group (67.39%). 116 patients had squamous cell carcinoma histology while 10 patients had adenocarcinoma histology. Most of the patients had stage II and stage III disease (85 patients). At last, follow up out of 138 patients 75 (54.35) were alive. 3 year disease-free survival was 54.34% and 3-year overall survival was 72.46%. Conclusion: Carcinoma cervix is an uncommon malignancy in Kashmir because of different socio-cultural and religious practices but the response to treatment, toxicity profile, and survival are similar to the rest of the world.

Clinicopathological Profile of Non-small Cell Lung Cancer and the Changing Trends in Its Histopathology: Experience From a Tertiary Care Cancer Center in Kashmir, India.

Background The overall frequency and incidence of different cancers across the globe, including lung cancer, are marked by ethnic and geographical variations. Lung cancer is the most commonly diagnosed cancer worldwide that inflicts most of the cancer deaths. Non-small cell lung cancer (NSCLC) constitutes most lung cancer cases. The aim of this study was to find the frequency and clinicopathological characteristics of NSCLC in high incidence zone of Kashmir, an ethnically and geographically distinct area in Northern India. Material and methods The study was conducted to evaluate the clinicopathological profile of NSCLC at a tertiary care cancer center, Sher-I-Kashmir Institute of Medical Sciences (SKIMS). The patients and case records were analyzed for clinical presentation and demographic features, smoking status, radiological features, histopathological type, and stage of their disease at presentation. Results The study included 1557 NSCLC patients registered over a period of seven years, i.e., 2008-2014. Most of the patients belonged to rural areas (70%). The median age of the whole cohort was 58.0 years (ranges 22-95 years), and the male-to-female ratio was 3.7:1 (male = 1231 and female = 326). Smokers comprised 77.39% of cases, and Hookah was the most common form of smoking (65.06%). The ratio of squamous cell carcinoma and adenocarcinoma was 3.7:1 (67.5% vs. 24.9%). Stage III and IV disease accounted for 93% of cases (30.6% and 62.7%, respectively). Squamous cell carcinoma histopathology was dominant in smokers (74.3%) compared to adenocarcinoma (19%), while squamous cell carcinoma and adenocarcinoma histopathology ran parallel in nonsmokers (45.1% and 44%, respectively). Most of the patients had an Eastern Cooperative Oncology Group (ECOG) performance status between 1 and 2 (79%).  Conclusion We conclude Kashmir region is a very high-risk area for lung cancer, with NSCLC showing a high incidence. Most of our patients present in advanced stages, and the frequency of adenocarcinoma is showing an increasing trend over the years from 2008-2014.
