Cytological diagnosis of a rare case of cutaneous metastasis from transitional cell carcinoma, renal pelvis

Transitional cell carcinoma (TCC) arising from renal pelvis rarely gives rise to cutaneous metastasis. Due to the insufficient literature, the exact incidence is not known till date. Moreover, the diagnosis is confirmed on histopathological examination with the aid of immunohistochemistry wherever needed. We are presenting a case of a 70-year-old female with metastatic TCC from the renal pelvis to the abdominal skin, which was diagnosed on cytology alone along with the cell block preparation. We also highlight the important cytomorphological and immunohistochemical features noted, which need to be known to avoid any diagnostic delay

Lung metastasis in primary cutaneous adenoid cystic carcinoma – Clinicopathological evaluation of a rare case with review of literature

Primary cutaneous adenoid cystic carcinoma (ACC) is an extremely rare and indolent cutaneous malignancy with very infrequent distant metastasis. We present a case of primary cutaneous ACC with bilateral lung metastases in a 57-year-old male along with literature review. To the best of our knowledge this is the tenth case of primary cutaneous ACC reported presenting with distant metastasis

Multiple cutaneous metastases in a patient of carcinoma tonsil – Report of a rare case

Carcinoma tonsil with visceral metastasis is a rare entity, and cutaneous metastasis is seen even more infrequently. We present a case of a 55-year-old male with carcinoma tonsil having received concurrent chemo radiotherapy, presenting with multiple cutaneous metastases to the scalp and thigh. To the best of our knowledge, till date only two similar cases of carcinoma tonsil with cutaneous metastasis have been reported in the English literature

Spectrum of fungal infection in head and neck cancer patients on chemoradiotherapy

Background: Radiotherapy for head and neck cancers (HNC) causes alteration of oral mucosal barrier predisposing it to colonization and infection. Such infections often result in pain and burning sensation thus contributing to major morbidity. Objective: 1. To identify the fungi isolated from the patients undergoing radiotherapy for HNC. 2. To determine their antifungal susceptibility and week of colonization. 3. To find out association between oral fungal infection and severity of oral mucositis. Materials and methods: Study was done on 50 patients of HNC treated with concurrent chemoradiotherapy. Three samples (throat, urine, blood) were collected for fungal culture and sensitivity. These samples were collected before the start of radiotherapy, during radiotherapy (2nd and 6th week) and post radiotherapy (10th week). Results: Only 49 patients were available for analysis. Fungal infection was found in 27/49 patients (55.10%) out of which Non-albicans Candida was isolated in 18/49 (36.73%) and Candida albicans in 9/49 (18.36%) cases. About 66.66% (18/27) isolates were sensitive to fluconazole. Maximum isolation of yeast was during 6th week of radiotherapy. All grade 4 and 71.42% of grade 3 oral mucositis were found in patients who were positive for fungal infection. Conclusion: The spectrum of fungal species in throat swab was: Non-albicans Candida and Candida albicans observed in 36.73% and 18.36% of patients respectively. Higher rate of fungal colonization and infection was found in patients with grade 3/4 oral mucositis. Prophylactic fluconazole in HNC patients on concurrent chemoradiotherapy has the potential to reduce emerging invasive fungal infection and its associated morbidity

A real‐world data of Immune checkpoint inhibitors in solid tumors from India

Abstract Background Checkpoint inhibitors (Nivolumab and Pembrolizumab) are approved for multiple indications in solid tumors. However access to these therapies is limited in low and middle income countries. Hence we performed an audit to identify accessibility, adverse event rates, compliance, progression free survival and overall survival in solid tumors. Methods This was a single center retrospective analysis of prospective data base of patients with non‐melanoma solid tumors who were treated with immunotherapy from August 2015 to November 2018. Adverse events during immunotherapy were documented and graded using CTCAE (Common terminology criteria for adverse events), v. 4.02. The response rates to immunotherapy, toxicities and the time to onset and resolution of toxicities were also evaluated as secondary endpoints. Results Out of 9610 patients, only 155 patients (1.61%) could receive immunotherapy. The most common malignancies included metastatic non‐small cell lung cancer, metastatic renal cell carcinoma, metastatic urothelial carcinoma and relapsed/recurrent head and neck squamous cell carcinoma. Median overall survival in patients who received immunotherapy in non‐melanoma solid malignancies was 5.37 months (95% CI, 3.73–9.73). Poor performance status at baseline was the only adverse prognostic factor. The median progression free survival was 2.57 months (95% CI, 1.73–3.83). Immunotherapy was well tolerated with most common side effects being fatigue 14.8% and anorexia 5.8%. The cumulative incidence of immune related adverse events like hepatitis, pneumonitis, colitis and nephritis was less than 10%. Conclusion Real‐world data in Indian setting confirms the benefit of immunotherapy in patients with advanced non‐melanoma solid tumors

Low-Dose Immunotherapy in Head and Neck Cancer:A Randomized Study

PURPOSE The regimens approved for the treatment of advanced head and neck squamous cell carcinoma are accessible to only 1%-3% of patients in low- and middle-income countries because of their cost. In our previous study, metronomic chemotherapy improved survival in this setting. Retrospective data suggest that a low dose of nivolumab may be efficacious. Hence, we aimed to assess whether the addition of low-dose nivolumab to triple metronomic chemotherapy (TMC) improved overall survival (OS).METHODS This was a randomized phase III superiority study. Adult patients with recurrent or newly diagnosed advanced head and neck squamous cell carcinoma being treated with palliative intent with an Eastern Cooperative Oncology Group performance status of 0-1 were eligible. Patients were randomly assigned 1:1 to TMC consisting of oral methotrexate 9 mg/m2 once a week, celecoxib 200 mg twice daily, and erlotinib 150 mg once daily, or TMC with intravenous nivolumab (TMC-I) 20 mg flat dose once every 3 weeks. The primary end point was 1-year OS.RESULTS One hundred fifty-one patients were randomly assigned, 75 in TMC and 76 in the TMC-I arm. The addition of low-dose nivolumab led to an improvement in the 1-year OS from 16.3% (95% CI, 8.0 to 27.4) to 43.4% (95% CI, 30.8 to 55.3; hazard ratio, 0.545; 95% CI, 0.362 to 0.820; P =.0036). The median OS in TMC and TMC-I arms was 6.7 months (95% CI, 5.8 to 8.1) and 10.1 months (95% CI, 7.4 to 12.6), respectively (P =.0052). The rate of grade 3 and above adverse events was 50% and 46.1% in TMC and TMC-I arms, respectively (P =.744).CONCLUSION To our knowledge, this is the first-ever randomized study to demonstrate that the addition of low-dose nivolumab to metronomic chemotherapy improved OS and is an alternative standard of care for those who cannot access full-dose checkpoint inhibitors.</p
