Background: The use of high-dose chemotherapy with autologous hematopoietic cell transplantation is well established as a potentially curative approach in patients with relapsed or refractory disease in testicular Germ cell tumours after initial cisplatin-based chemotherapy. The use of tandem transplant with high-dose carboplatin and etoposide conditioning has been a tried and is a feasible option in relapse setting.Overall, HDCTand Autologous stem cell transplant can offer cure rates of up to 60% in the relapsed GCTsetting. Data on Tandem HDCTand ASCTis very limited in Indian subcontinent. Hence we report our experience with respect to safety, efcacy and tolerability, survival outcomes of HDCT/ ASCT in patients with relapsed GCT. Methods: Patients who were diagnosed with relapsed or refractory Germ cell tumours and underwent Tandem HDCT and ASCT were analysed from patient records from 2013 to 2020. Results: Both our patients received BEP (bleomycin, etoposide, and cisplatin) as rst-line therapy. HDCT was done after 2nd line salvage chemotherapies in both patients. Both patients were treated with 2 courses of High-dose carboplatin (700mg/m2) and etoposide(750mg/m2) as conditioning regimen followed by stem cell rescue(CD34+ stem cells yield – 5 to 6x106 cells/kg ) 3-4 weeks apart. Grade ¾ toxicities including myelosuppression, diarrhea, mucositis were observed in both patients. After ASCT both patients were followed up with imaging and serial monitoring of tumour markers. 1st patient died 3 months after ASCT due to disease relapse and our 2nd patient was disease free for 22 months, after which he developed progressive disease in brain and succumbed to disease. Conclusion: This is the rst report from India on tandem HDCT with ACST in relapsed GCTs. Tandem HDCT/ASCT seems to be safe and feasible option in relapsed/ refractory testicular GCT's.

Background: Langerhans cell histiocytosis (LCH) comprises a diverse group of disorders where pathologic Langerhans cells accumulate in a variety of organs. Aims and objectives of the study is to analyse the clinical manifestations and treatment outcomes of patients diagnosed with LCH in a tertiary cancer hospital in South India.Methods: Retrospective analysis of the case records of patients presenting with histological proven case of LCH over a period of 7 years from 2011 to 2018, being treated at Vydehi Institute of Medical Sciences and Research Centre.Results: 10 patients with biopsy proven LCH were included. The median age of diagnosis was 8 years (range 1 to 73 years) and 3 patients aged 18 years or older at the time of diagnosis. The male: female ratio was 3:2. Multisystem involvement was found in 4 patients (40%) and Single system Involvement in remaining 6 patients. Isolated bone lesions were found in 4 patients (40%), 1 patient had isolated Lymph node involvement; 1 patient had oral cavity lesion. None of the 4 patients with multisystem diseases had skin/mucosal involvement; 3 had bony involvement, 2 patients had lung involvement. One patients with multisystem disease expired while 5 patients were lost to follow-up. 4 out of the 10 patients are on regular follow-up and are in remission.Conclusions: Despite limitation by the retrospective nature, this descriptive study was done to provide further disease information regarding Indian population. Data from this study clearly confirms the known fact that most of the patients with Single System LCH have a very good response rate. Patients with multisystem disease have the highest risk of disease related mortality and morbidity as one among the 4 patients with multisystem disease died just after initiating treatment.

Background: Anthracycline is one of the commonly used chemotherapeutic agents in the treatment of malignancies and their efficacy is undermined by potential life-threatening cardiotoxicity.  The aim of this study is to compare the cardiotoxicity in patients receiving standard short infusion (15-30 minutes) versus prolonged infusion (6 hours) of doxorubicin in the study group.Methods: In this study 80 patients who were planned for treatment with Doxorubicin >200 mg/m2 were included in this study and they were randomly allotted to either of the treatment group. Each patient was assessed clinically (History, Pulse rate, Blood pressure) along with ECG ,ECHO prior to initiation of chemotherapy, after completion of 200 mg/m2 of Doxorubicin, 3 months and 6 months after chemotherapy.Results: There were 40 patients in each group, and they received a total of 384 cycles of Doxorubicin containing regimens according to respective protocols. The median number of cycles was four (range four to six cycles). The mean cumulative dose of doxorubicin was 271.5 mg/m2 in the group which received standard short infusion and 264 mg/m2 in the group which received the drug by prolonged infusion. However, none of the patients developed any cardiac symptoms during or after the planned chemotherapy nor was there a drop in ejection fraction on serial ECHO.Conclusions: There was no benefit of prolonged infusion of doxorubicin as compared to the standard rapid infusion in terms of doxorubicin induced cardiotoxicity. At present, standard rapid infusion is the best option.

Background: The presence of second synchronous or metachronous primary malignancies in a cancer patient is not a rare phenomenon. Our study is an endeavour to present data on the frequency, types, and outcomes of double primary malignancies in Indian cancer patients.Methods: This was a retrospective study conducted in 28 cancer patients diagnosed with histologically confirmed double malignancy. Retrospective data of the cancer site, patient’s age at the presentation, gender, type of cancer (synchronous/metachronous), treatment, and outcome were recorded from patients presented with double malignancies from January 2012 to January 2019.Results: Among 28 patients (18 females; 10 males) with multiple primary malignancies, 10 (35.7%) and 18 patients (64.3%), respectively, had synchronous and metachronous primary malignancies. Overall, breast, gynecological, head, and neck cancer were the most common primary malignancies. Gastrointestinal tract, breast, and lung cancer emerged to be the most common second primary malignancy sites. Squamous cell carcinoma (SCC) and invasive ductal carcinoma (IDC) were the most common histopathological types of double malignancies. The majority of the patients received appropriate treatment for both the malignancies.Conclusions: Data from the present study clearly suggest that the occurrence of second primary malignancy is not rare in Indian cancer patients. The double malignancies can occur at any stage and for any type of cancer. Hence, we wish to highlight that the clinician should always be aware of the possibility of developing second malignancy either during evaluation or in follow up of a patient with malignancy.
