ABSTRACT
Introduction and Aims: Acute myeloid leukemia (AML) in adults has poor prognosis. The epidemiologic profile of patients varies greatly in different geographic locations and so do the cytogenetic abnormalities and the FAB subtype of the AML. We intended to study the clinical profile, cytogenetics, and outcomes with standard of care treatment on our population in India. Methods: This was a retrospective study with systematic review of 203 case records. Primary objectives were to know the demographic profile of AML, prevalence of various FAB subtypes, cytogenetic abnormalities, and treatment outcomes at our center, which is a referral center of oncology. Two treatment outcomes considered in study for patients of AML were achievement of remission status of the bone marrow postintensive induction chemotherapy and sustenance of the remission for 6 months, once remission is achieved. Secondary objective was to study these outcomes in non-M3 AML in relation to cytogenetics. Results: Median age was 39 years. The most common FAB subtype observed was AML M2. About 65.6% patients achieved complete remission (CR), and 42.4% patients could sustain it for next 6 months. Cytogenetics correlated with prognosis but not age. Conclusions: Our population differs from the Western population regarding lower age, lower prevalence of adverse cytogenetics, and higher prevalence of favorable cytogenetic abnormalities. Cytogenetics had a good correlation with CR rates after chemotherapy as well as its sustenance
ABSTRACT
BACKGROUND: Synchronous occurrence of two malignant tumors is a rare event. With increasing use of sophisticated imaging modalities for staging, synchronous multiple tumors are more commonly detected now. Assuming the second primary malignancy as metastasis will change the intent of treatment from curative to palliative, greater awareness among oncologists is of paramount importance. This study is an example where thorough clinical examination and proper judgment resulted in correct diagnosis and appropriate treatment. MATERIALS AND METHODS: This is a prospective descriptive study. Patients diagnosed with synchronous primary tumors from January 2016 to November 2017 at our center were reviewed. RESULTS: Ten cases of synchronous primary malignancies were detected during this period. A total of 20 primary tumors were diagnosed. Lung carcinoma and gastrointestinal malignancies were the most common (five patients each). The median age was 59.5 years. Seven patients were male. Second primary tumor was suspected in four patients during clinical examination, while in six patients it was suspected on imaging. Even in the presence of two primary tumors, three patients were treated with curative intent. CONCLUSION: Possibility of synchronous second primary malignancy should always be kept whenever a distant deposit is detected at an unusual site. Histopathological evaluation of the lesion before assuming a metastasis will lead to accurate diagnosis, staging, and appropriate treatment.
ABSTRACT
BACKGROUND: Recently published prospective clinical trials and two meta-analyses have shown that addition of induction chemotherapy (IC) to concurrent chemoradiation (CRT) could potentially improve outcomes in comparison to CRT alone, in locoregionally advanced nasopharyngeal carcinoma (LANPC). Although it remains unclear which is the best IC regimen to be offered and for how many cycles. Unfortunately, till date, there are no published data from India regarding the outcomes of various commonly used IC regimens before CRT, in LANPC. MATERIALS AND METHODS: Patients diagnosed with LANPC from January 2012 to December 2017, who received three cycles of IC before definitive CRT were reviewed retrospectively. Patients' profile, toxicity of IC, response rates, failure-free survival, and overall survival (OS) were evaluated. RESULTS: A total 34 patients with LANPC who received IC were reviewed. The median age at diagnosis was 36 years, and the majority were males (67.6%, n = 23). Nineteen patients received IC with paclitaxel plus cisplatin regimen (TP) and the remaining 15 patients received IC with docetaxel/paclitaxel plus cisplatin plus 5-FU regimen (TPF). The overall response rates after three cycles of TP and TPF IC were 68.4% and 80%, respectively, and the corresponding rates were 84.2%and 93.3%, respectively, 2 months after completion of CRT. At a median follow-up of 24 months, 2-year failure-free survival and OS for TP arm were 78.9% and 89.5%, and the corresponding rates for TPF arm were 86.7% and 93.3%, respectively. All Grade III–IV toxicities were numerically higher with triplet IC regimen in comparison to doublet regimen. CONCLUSION: In this retrospective analysis, there was no significant difference between taxane-based doublet and triplet IC regimens, in terms of survival outcomes, although Grade III–IV toxicities were numerically higher with triplet IC regimen. Clearly, these hypothesis-generating findings should be tested in a prospective randomized setting.
ABSTRACT
Primary parotid lymphoma [PPL] is an unusual entity and there is limited data in Indian population. Hence we undertook this retrospective observational study of primary parotid lymphoma at our Center in Southern India. This study includes 7 consecutive cases diagnosed as PPL by tissue biopsy/superficial/deep parotidectomy confirmed by immunohistochemistry between January 2007 and December 2012
Results: Median age was 54 years [range 29- 78 years], and it was more common in males. According to Ann Arbor stage, Advanced stage [stage III and IV] was seen in 2 [28.57%]. According to the International Prognostic Index [IPI], most [6] were low risk [85.7%]. Overall survival ranged from 1-45 months with median OS of 18 months. To conclude, PPL presents more often in early stage and low IPI score. Surgery +/- chemoimmunotherapy with radiotherapy to the parotid is the standard treatment at present
