Our objective is to review the current articles pertaining to multimodality treatment that surround the management of retromolar trigone (RMT) cancer patients. RMT tumors constitute a small minority of all oral cancers. Majority of these patients present with locally advanced stage and its treatment is challenging. Good oncologic outcomes can be achieved by advocating an aggressive surgical approach in combination with post operative radiation therapy. In this literature review we intend to discuss locally advanced trigone cancer and its outcome after the completion of the multimodality...
MIXED GERM CELL TUMOR OF OVARY AND MAYER ROKITANSKY KUSTNER HAUSER SYNDROME: AN UNUSUAL COMBINATION!
Germ cell tumor of ovary in young female is most common ovarian neoplasm but represent less than three percent of all ovarian malignancies in females. Mixed germ cell tumor is a variant of germ cell tumors and its presentation with Mayer Rokitansky Kustner Hauser Syndrome, which represents the most common type of utero-vaginal agenesis, is very unusual. However, for patients with primary amenorrhea, Mayer Rokitansky Kustner Hauser syndrome is the second common cause. We describe an interesting, uncommon and unexpected case in a young Indian female patient with primary amenorrhea due to this syndrome coexisting with mixed germ cell...
Primary involvement of vulva or breast by non-hodgkin lymphoma (NHL) is known to occur uncommonly. Only 24 cases of NHL vulva and around 250 cases of NHL breast alone have been reported, so far; but none with simultaneous involvement of the two sites together. We report the first case having both sites involved in a 35 year old Indian female.
Background & Objective Lung Cancer is a major health problem worldwide with high fatality rate. Smoking is a known to be the most important risk factor, though all smokers do not develop lung cancer. This is because individuals differ in metabolism of pro-carcinogens present in cigarette smoke by cytochrome P450 (CYP 450) enzymes. Variable forms of CYP450 enzymes are produced due to presence of multiple alleles or polymorphs of CYP 450 gene. CYP 1A1 polymorphisms were the first CYP genes to be associated with lung cancer. Several single nucleotide polymorphisms (SNPs) have been identified in CYP1A1 gene, some of which are suspected to be linked with lung cancer. This study has been done to find association of CYP1A1 genes- m1, m2, and m4 polymorphism with lung cancer in heavy smokers. Methods & Results This is an observational analytical study on heavy smoker eighty males, of which forty were with lung cancer (Group I) and remaining forty were with non-lung cancer (Group II). CYP1A1 gene m1, m2 and m4 polymorphism was detected by polymerase chain reaction- restriction fragment length polymorphism (PCR-RFLP) techniques. Steps involved in these techniques are DNA isolation, polymerase chain reaction, DNA electrophoresis and restriction fragment length polymorphism. CYP1A1 m1 Gene polymorphism was found in 3 out of 22 (13.6%) cases of squamous cell lung cancer and only 1 case (4.5%) had both the m1 and m2 gene polymorphisms. None of these polymorphisms was seen in non-lung cancer smokers and in patients with non-squamous cell lung cancer. Interpretation & Conclusion CYP1A1 gene related m1 and m2 polymorphisms may have some contributory role for lung squamous cell carcinoma development and m4 polymorphism has no role in development of lung cancer in Indian population of eastern part of Gujarat. All lung carcinoma cases may not have gene polymorphism of CYP1A1...
Anaplastic large cell lymphoma (ALCL) represents 2 to 3% of non-Hodgkin lymphoma (NHL). Anaplastic lymphoma kinase negative (ALK-) subtype accounts for 15-50% of all ALCL. Primary bone involvement in lymphoma is uncommon and constitutes less than 1% of all lymphomas and 4-5% of all extranodal NHL. Hence extra-nodal primary bone involvement in ALCL is even rarer. We report the 14th case of primary ALCL in a 38 year old Indian female. Other than the uncommon site, there is no reason not to keep NHL as differential diagnosis, as the condition responds too well to standard...
Background- Astroblastoma is partially understood, poorly reported and rare in occurrence tumor with significant dilemma regarding cellular origin, diagnostic criteria, clinical behavior, and management protocol. Material and method– Thorough search of published English scientific literature was made with search word Astroblastoma through Google Search, PubMed, Research Gate and Cochrane Library till June 2018. The reports thus collected were examined for data regarding age, gender, location and laterality of disease, pathological grade, treatment received, and outcome of treatment. Results– Data of 161 patients was retrieved from 72 publications. Median age at presentation was 18 years. Females were affected much more frequently than males. Most common site of involvement was the frontal lobe. Laterality data was inconsistent and sparingly reported. Most common presenting complaint was headache followed by history of seizure. Surgery was performed in majority of patients-79.6% of the patients underwent a gross total resection, 45% (44 out of 98 reported) had a high-grade tumor. Sixty patients received adjuvant radiation with a median dose of 54 Gy (Range 20-72), mostly for high grade, residual or recurrent disease. Adjuvant chemotherapy was used in 25 patients. Median follow-up was 43 months (range 1-238). Median overall survival was 138 months. Patients with a higher-grade tumor had significantly worse overall survival. Conclusion- Astroblastoma is rare but known to have two distinct grades, with higher-grade tumors bearing significantly poor survival. Maximal safe surgery is the standard. Though there is lack of consensus, adjuvant radiotherapy with or without Temozolamide should be considered in view of high rates of local...
Chronomodulated therapy or chronotherapy has gained popularity, beyond a fancy term, as a novel and logical method to exploit the best, by administering anti-cancer treatment at an optimal timing according to circadian rhythms of their anti-cancer action and/or repair mechanism of cancer & normal cells. Understanding of chronobiology and the results of clinical studies back up this new concept. Chronotherapy seems to have all the potential to become tomorrow’s accepted, refined oncology practice without adding much to the cost of existing...
Peripheral neuropathy is a structural or functional abnormality of peripheral nerves giving rise to neuropathic symptoms. Neuropathic symptoms can be motor, sensory and autonomic or varied combination of these major categories. Chemotherapeutic agents frequently cause various neuropathic symptoms and signs depending upon culprit agent, its dose and duration. Chemotherapy-Induced Peripheral Neurotoxicity is a common, disabling and dose-limiting side-effect of cancer treatment and its assessment is difficult. Some patients complain of tingling, numbness and pain in distal extremities while others may also develop motor and autonomic symptoms. Some patients remain symptomatic even after discontinuation of offending drugs. Patients with chemotherapy induced neuropathy bear higher healthcare cost than cancer patients without neuropathy. As new chemotherapeutic agents are being developed it is important to measure chemotherapy induced peripheral neuropathy accurately so that it can be recognized at an earlier stage, the treatment can be modified appropriately and disease progression can be monitored. An added advantage would be a possibility of reliable comparison between neuropathic side effect of newer and older chemotherapeutic...
Partial nephrectomy is performed more commonly for small, low-stage renal tumors. The main advantage of partial nephrectomy over radical nephrectomy is the avoidance of renal insufficiency. The major disadvantages are the possibility of local recurrence and perioperative complications. In this article, we discuss the technical aspects of the nephron-sparing surgery and review the literature pertaining to it, in order to put the management of renal cancer into a modern...
Intensity modulated radiation therapy (IMRT) is a technique to deliver a highly conformal radiation dose distribution, that too with wide spectrum ranging from conventional IMRT, through Volumetric Modulated Arc Therapy (VMAT) to most advanced form called Dense Angularly Sampled and Sparse Intensity Modulated Radiation Therapy (DASSIM-RT). The article intends to overview the current status of the technology....
