Screening for Lung Cancer in India: Expert Opinion Statement.

Lung cancer (LC) has the highest rate of disability-adjusted life years (DALY) of all cancers in India. A large majority of patients with LC present with advanced disease, resulting in poor survival rates. Early diagnosis can improve survival outcomes as the patients can be treated with curative intent. The National Lung Screening Trial (NLST), in 53,454 persons at high risk for LC in the US, showed a 20% (95% confidence interval of 6.8-26.7; p = 0.004) relative reduction in LC-specific mortality in the patients screened with low-dose computed tomography (LDCT) compared with chest X-ray. To date, India does not have a formal LC screening (LCS) program. As a panel of experts, we reviewed a synthesis of a targeted literature search on the burden of LC, the current status of diagnosis of LC, barriers to early diagnosis, current referral pathways, LC risk patterns, use of artificial intelligence (AI) and risk calculators for risk assessment, and a multidisciplinary team (MDT) approach to diagnosis LC. We used the existing international LCS guidelines, data from published literature, and clinical experience to depict the characteristics of the population at risk of LC in India-young age (<40 years), smoking, especially the predominance of bidi smoking (an indigenous form of tobacco smoking), exposure to biomass fuel smoke, especially in rural women, and air pollution being the prominent features. LC in India is characterized by a higher rate of driver mutations and adenocarcinomatous histology. Here, we present the expert opinion on risk-based LCS in India and discuss the challenges, facilitators, and research priorities for the effective rollout of LCS in India.

Shared Decision-Making and Medicolegal Aspects: Delivering High-Quality Cancer Care in India.

It is often difficult for people with cancer to make decisions for their care. The aim of this review is to understand the importance of shared decisionmaking (SDM) in Indian clinical scenario and identify the gaps when compared to practices in the Western world. A systematic search (2000-2019) was executed in Medline and Google Scholar using predefined keywords. Of the approximate 400 articles retrieved, 43 articles (Indian: 5; Western: 38) were selected for literature review. Literature review revealed the paucity of information on SDM in India compared to the Western world data. This may contribute to patientreported physical or psychological harms, life disruptions, or unnecessary financial costs. Western world data demonstrate the involvement and sharing of information by both patient and physician, collective efforts of the two to build consensus for preferred treatment. In India, involvement of patients in the planning for treatment is largely limited to tertiary care centers, academic institutes, or only when the cost of therapy is high. In addition, cultural beliefs and prejudices impact the extent of participation and engagement of a patient in disease management. Communication failures have been found to strongly correlate with the medicolegal malpractice litigations. Research is needed to explore ways to how to incorporate SDM into routine oncology practice. India has a high unmet need towards SDM in diagnosis and treatment of cancer. Physicians need to involve patients or their immediate family members in decision making, to make it a patient-centric approach as well. SDM enforces to avoid uninformed decisionmaking or a lack of trust in the treating physician's knowledge and skills. Physician and patient education, development of tools and guiding policies, widespread implementation, and periodic assessments may advance the practice of SDM.

Dermatological Side Effects of Epidermal Growth Factor Receptor Inhibitors: 'PRIDE' Complex.

Epidermal growth factor receptor (EGFR) inhibitor therapy has become the standard treatment for non-small cell lung cancer and head neck malignancy. This class of drug comprises EGFR inhibitors (erlotinib and gefitinib) and monoclonal antibody (cetuximab). Use of this class of drugs has been associated frequently with dermatological side effects termed as PRIDE complex-Papulopustules and/or paronychia, Regulatory abnormalities of hair growth, Itching, Dryness due to EGFR inhibitors. We hereby report the cutaneous side effects of EGFR inhibitor therapy in 15 patients of lung and head/neck cancer. The major clinical findings being acneiform eruption and severe xerosis of skin. Management of these dermatological adverse effects rarely requires discontinuation of targeted therapy and can be managed symptomatically.

Weekly chemotherapy as Induction chemotherapy in locally advanced head and neck cancer for patients ineligible for 3 weekly maximum tolerable dose chemotherapy.

OBJECTIVE: To study the safety and efficacy of weekly chemotherapy as part of induction chemotherapy, in locally advanced head and neck cancer for patients, who are unfit for upfront radical treatment. MATERIALS AND METHODS: It is a retrospective analysis of on-use weekly chemotherapy as Induction chemotherapy in locally advanced head and neck cancer, who are technically unresectable are unfit for upfront radical treatment. Induction chemotherapy given was a 2 drug combination of paclitaxel (80 mg/m 2 ) and carboplatin AUC 2. The decision to give weekly induction chemotherapy was given on the basis of presence of 2 more following features: Poor performance status (ECOG PS 2-3), presence of uncontrolled co morbidities, BMI below 18.5 kg/m 2 and age more than 60 years. The Statistical Package for the Social Sciences software (SPSS version 16.0) was used for analysis. The response rates, toxicity (accordance with CTCAE vs. 4.02), completion rate (Cp) of radical intent treatment post neoadjuvant chemotherapy (NACT), progression-free survival (PFS) and overall survival (OS) are reported. RESULTS: Fifteen patients were considered for such therapy. Fourteen out of fifteen patients completed NACT. The median numbers of planned weekly cycles were 6 (3-8). Response (CR + PR) was seen in 10 patients. Overall grade 3-4 toxicity was seen in 6 patients. No toxicity related mortality was noted. The calculated completion rate (Cp) of radical intent treatment post NACT was 46.7%. The median PFS and OS were 10.36 months (95% CI 6.73-14.00 months) and 16.53 months (95% CI 4.22-28.84). CONCLUSION: Use of induction chemotherapy with weekly regimen is safe and effective selected cohort of patients with locally advanced disease who are unfit for upfront radical treatment.

Primary cardiac diffuse large B-cell lymphoma with activated B-cell-like phenotype.

Primary cardiac lymphoma (PCL) is a rare and fatal disorder. It may often mimic other common cardiac tumors like cardiac myxoma because of similarities in the clinical presentation. We report a case of PCL of diffuse large B-cell type, in a 38-year-old, immunocompetent male who presented with superior vena cava syndrome that was excised as a myxoma. Histology revealed a large cell population diffusely and strongly expressing CD45, CD20, MUM1/IRF4 and FOXP1 hinting at an activated B-cell (ABC)-like phenotype. After four cycles of Rituximab with CHOP (cyclophosphamide, hydroxydaunorubicin, Oncovin, and prednisolone) the tumor regressed completely but the patient had a relapse and subsequently succumbed to the disease confirming the aggressive nature. The aggressive behavior of PCL may be possibly linked to its ABC-like origin.

Palliation of dysphagia with radiotherapy for exophytic base tongue metastases in a case of renal cell carcinoma.

Base tongue involvement is a rare presentation of lingual metastases from renal cell carcinoma. A 48-year-old gentleman was treated with open radical nephrectomy and adjuvant radiotherapy for Stage II Furhman grade I clear cell carcinoma of the left kidney at an outside hospital. He presented metachronously 5 years later with progressive dysphagia and change of voice. Clinicoradiological evaluation revealed a large exophytic mass in the oropharynx with epicenter in the right base of tongue. Metastatic workup revealed widespread dissemination to multiple organs and bone. In view of predominant symptom of dysphagia, base tongue metastasis was treated with protracted course of palliative radiotherapy to a dose of 50 Gy in conventional fractionation over 5 weeks. This resulted in excellent and durable response at the base tongue lesion (till the time of last follow-up). Radiation therapy is an acceptable palliative strategy for advanced lingual metastasis as it produces prompt relief of pain, bleeding, and dysphagia.

Neoadjuvant chemotherapy or chemoradiotherapy in head and neck cancer.

The multidisciplinary approach to treating squamous cell carcinoma of the head and neck is complex and evolving. Chemotherapy is increasingly being incorporated into the treatment of squamous cell carcinoma of the head and neck. Previously, radiotherapy following surgery was the standard approach to the treatment of loco regionally advanced resectable disease. Data from randomized trials have confirmed the benefits of concurrent chemo radiotherapy in the adjuvant setting. Chemo radiotherapy is also the recommended approach for unresectable disease. Advanced loco regional disease is the most frequent clinical situation in Head and Neck cancer. The standard of care for most clinicians is a multidisciplinary treatment with concomitant chemotherapy plus radiotherapy (CRT). However, retrospective studies have shown that in patients treated with CRT there was a relative increase in systemic relapse due to a lack of systemic control. For this reason a renewed interest has appeared for the incorporation of induction chemotherapy in the treatment of locally advanced Head and Neck Cancer. Furthermore new combination regimens with taxanes have shown to be more active than the classical cisplatin and 5-fluorouracil induction regimen. Novel targeted agents, such as epidermal growth factor receptor antagonists, are showing promise in the treatment of patients with both loco regionally advanced and recurrent/metastatic squamous cell carcinoma of the head and neck.

Clinical outcome of 36 male patients with primary urethral carcinoma: a single center experience.

AIM: Retrospective analysis of male urethral carcinoma to assess the best therapeutic approach to the management of this tumor. METHODS: A review of 36 cases of male urethral carcinoma diagnosed and treated at our center was performed. Clinical features, treatment modality and outcomes were analysed. RESULTS: The overall median survival time was 55.16 months. The 5-year overall and disease-free survival rate for the cohort was 49% and 23%, respectively. The 5-year survival is 67% for low-stage versus 33% for high-stage tumors and is significantly different (P = 0.001). The survival was 72% for tumors of the distal urethra versus 36% for tumors of the proximal, with a P-value of 0.02. CONCLUSION: The tumor location and clinicopathological stage were the most important predictors of the disease-free and overall survival. Multimodal approach is necessary for achieving local control especially for proximal and higher stage tumors.
