Concurrent chemotherapy with high-dose rate brachytherapy after treatment with chemoradiotherapy in cases of locally advanced carcinoma cervix: A study from rural area of Maharashtra, India.

Aim: This study aims to evaluate the efficacy, feasibility, tolerability, and toxicity of concurrent chemotherapy and brachytherapy for locally advanced cervical carcinoma. Materials and Methods: Forty patients of cervical carcinoma were included in this study. The study period ranges from October 2016 to September 2019. Patients were evaluated and treated as per the protocol: external beam radiotherapy (50 Gy in 25 fractions) and concurrent weekly chemotherapy with injection (Inj.) cisplatin (30 mg/m2) followed by high-dose rate brachytherapy (3 fractions of 7 Gy each) and concurrent chemotherapy Inj. cisplatin (30 mg/m2). Results: Out of 40 patients enrolled in the study, 36 patients completed the treatment (17 Stage II and 19 Stage III). The incidence of Grade I and II skin toxicities were 78% and 10%, respectively. The incidence of genitourinary toxicities with respect to Grade I and II were 72% and 12%, respectively. There were Grade III hematological toxicities in two patients and the brachytherapy treatment was delayed for 4-6 days. The overall complete response was found in 28 (78%) patients, partial response in six (16.7%) patients, and progressive disease in two (5.6%) patients at 3 months of follow-up. On the last follow-up, 21 (58%) patients were disease-free and there was disease failure in seven patients (5 local recurrence and 2 with distant metastasis). Conclusion: Brachytherapy with the addition of concurrent chemotherapy is effective and feasible with acceptable toxicity for advanced stages of carcinoma cervix. This study upholds an interesting approach that can be regarded as feasible and tolerable for cervical cancer patients.

Safety and efficacy of nimotuzumab with concurrent chemoradiotherapy in unresectable locally advanced squamous cell carcinoma of head and neck: An Indian rural hospital experience.

CONTEXT: Nimotuzumab is the only anti-epidermal growth factor receptor monoclonal antibody which can be safely added to concurrent chemoradiotherapy (CRT) to improve efficacy in the management of unresectable, locally advanced squamous cell carcinoma of head and neck (LA-SCCHN). However, the evidence available on this is limited. AIMS: We retrospectively investigated efficacy and safety of nimotuzumab when combined with chemoradiation for LA-SCCHN. SETTINGS AND DESIGN: Hospital records of 39 patients from January 2012 to December 2016 diagnosed with locally advanced (Stage III-IVb), unresectable SCCHN, and treated with concurrent CRT with weekly nimotuzumab were reviewed retrospectively after fulfilling the inclusion/exclusion criteria. SUBJECTS AND METHODS: Tumor response was calculated as per response evaluation criteria in solid tumors criteria 1.1. Association of tumor response with independent variables was assessed. Overall survival (OS) and progression-free survival (PFS) were calculated. All patients were assessed for toxicity as per common terminology criteria for adverse events Common Terminology Criteria for Adverse Events v 4.0 (U.S. Department of health and human services, National Institutes of Health, National Cancer Institute). RESULTS: At 6 months after completion of treatment, objective response rate was 97.44% with 26 (66.67%) patients attaining Complete response (CR), 12 (30.77%) patients with Partial response (PR), and one patient (2.56%) had stable disease. Subgroup analysis did not show a significant association of tumor response with independent factors. OS at 1 and 2-year was 100% and 72.9%, while PFS at 1 and 2-year was 87% and 54.40%. The incidence of Grade I, II, III, and IV toxicity was 30%, 18.18%, 41.82%, and 10%, respectively. No grade V toxicity was observed. Common adverse events observed were mucositis (33.64%), skin reaction (24.55%), neutropenia (20.91%), vomiting (18.18%), and diarrhea (2.73%). CONCLUSIONS: Nimotuzumab is an efficacious and safe option when added to concurrent CRT in unresectable, LA-SCCHN.
