CONCOMITANT CHEMORADIATION IN HEAD AND NECK CANCER: ROLE OF 5-FU ANALOGS.

Head and neck cancer forms the major chunk of cancer patients in developing country like India. About 2/3rd of the patients present in locally advanced stage in which the cure rates are low. Concomitant chemoradiation with platinum compounds is the standard treatment for such patients as it offers organ and function preservation with better quality of life. MACH-NC update (2009) shows that concomitant chemoradiation provides an absolute survival benefit of 6.5% at 5 years. Many chemotherapeutic agents including 5-FU, taxanes and biologically targeted therapy have been investigated in an effort to maximize the locoregional and survival in locally advanced head and neck cancer. Oral chemotherapeutic agent gives the ease of self medication on daily basis without the need for hospital admission and intravenous infusion. Theoretically daily administration of oral chemotherapy agent mimics the continous infusion of a parenteral agent. Since infusional 5-FU along with Radical RT has achieved a complete response rate of 68% for 5-FU arm versus 56% for placebo arm (p=0.04) with the overall median survival of 33 months for 5-FU versus 25 months for placebo arm, Capecitabine (analog of 5-FU) in low doses have been used in concomitant setting for locally advanced head and neck cancer. Overall response rate observed has been 33-89% with manageable toxicity and near total patient compliance. The maximally tolerated dose to be given daily during radiation therapy is 500 mg/m2 b.i.d. Lower dose doses of 250-350 mg/m2 have also been used in concomitant with lesser toxicity and greater...

TARGETING IMMUNITY TO TREAT CANCERS- A BRIEF REVIEW

Cancer cells have a multitude of mechanisms to avoid and suppress immunity. Normal cells when exposed to chemical carcinogens, irradiation and certain viruses get transformed to cancer cells which can grow indefinitely. These cells have decreased requirements for growth factors; do not undergo apoptosis resulting in malignancy. The tumor cells have various antigens which are responsible for the generation of immune responses towards that particular tumor. There are two types of tumor antigens; tumors specific transplantation antigens (TSTAs) and tumor associated transplantation antigens (TATAs). The TSTAs are specific to tumor, result from mutations which alter the cellular proteins while TATAs may be proteins present in or during some stages of fetal development but not expressed or expressed at low levels in normal adult cells. Adoptive T-cell therapy involves the ex vivo cultivation of T cells with activity against a specific target cancer antigen to increase the frequency of these T cells to achieve therapeutic levels and then infuse them back into the patient. Oncolytic viruses selectively infect, replicate in, and kill tumor cells with no or limited impact on normal tissues which means that tumor cells have surface receptors to bind the virus. Monoclonal antibodies (mAbs) are immunoglobulins derived from a single clone of B cells, act by targeting an antigen which acts a ligand of receptor involved in signal transduction within the...

UNVEILING THE MYSTERIOUS WORLD OF SALIVARY DUCT CARCINOMA OF THE PAROTID GLAND- A RARE CASE REPORT AND REVIEW OF THE LITERATURE.

Among many variants of salivary gland tumors, salivary duct carcinoma (SDC) of the parotid gland is a highly aggressive and rare malignant tumor which ranks among those with the worst prognosis and a significant mortality. These tumors got their name based on its microscopic resemblance and being analogous to similar schemes in the ductal carcinoma of the breast. The characteristic microscopic features of salivary duct carcinoma are composed of comedo necrosis, a cribriform and papillary pattern of intraductal growth and aggressive infiltration to adjacent structures. Majority of cases are typically treated with radical parotidectomy with or without neck dissection followed by adjuvant radiotherapy. We present a case of a 60 year old male patient who presented with progressive facial paralysis and right parotid swelling. FNAC was positive for malignancy. PET-CT showed a lesion in right superficial lobe of parotid with bilateral neck nodes. Patient underwent right total parotidectomy with right radical neck dissection and left modified neck dissection. Facial nerve was preserved. Microscopic examination reported it as a salivary duct carcinoma, positive for Her2/neu antibody with lymph node metastasis (22/23). Patient received adjuvant radiotherapy and 12 cycles of Transtuzumab. There were no recurrences or metastases within 12 months of...

DESMOID TUMOR OF ANTERIOR ABDOMINAL WALL: A CASE REPORT AND REVIEW OF RECENT MANAGEMENT STRATEGIES

Desmoid tumor is a slow growing neoplasm with aggressive infiltration of adjacent tissue with very rare metastatic potential. We report a 35 years old female patient with desmoid tumor of the anterior abdominal wall who underwent primary resection followed by mesh pasty. Patient had a past history of abdominal surgery in form of caesarean section, and after 5 years of surgery, she presented with a lump over right hypochondrium since last one year. Patient was assessed before surgery by clinical evaluation, abdominal ultrasound, computerized axial tomography scanning (CT scan), magnetic resonance imaging (MRI), and histopathology and immunohistochemistry report.Patient was operated with wide local excision of rectus abdominis muscle mass with meshplasty under general anaesthesia. After all, histology in this case revealed a desmoid tumor with negative β-Catenin report of operated tissue. In view of the negative surgical margins, patient has been put on regular follow...
