Background: The prime output of Hospital Based Cancer Registries is stage and treatment based survival to evaluate patient care, but because of challenges of obtaining follow-up details a separate study on Patterns of Care and Survival for selected sites was initiated under the National Cancer Registry Programme of India. The results of stage and treatment based survival for head and neck cancers by individual organ sites are presented. Materials and Methods: A standardized Patient Information Form recorded the details and entered on-line at www.hbccrindia.org to a central repository - National Centre for Disease Informatics and Research. Cases from 12 institutions diagnosed between 1 January 2006 and 31 December 2008 comprised the study subjects. The patterns of treatment were examined for 14053 and survival for 4773 patients from five institutions who reported at least 70% follow-up as of 31 December 2012. Results: Surgical treatment with radiation for cancer tongue and mouth showed five year cumulative survival (FCS) of 67.5% and 60.4% respectively for locally advanced stage. Chemo-radiation compared to radiation alone showed better survival benefit of around 15% in both oro and hypo-pharyngeal cancers and their FCS was 40.0%; Hazard Ratio (HR):1.5;CI=1.2-1.9) and 38.7%; (HR):1.7; CI=1.3-2.2). Conclusions: The awareness about the requirement of concurrent chemo-radiation in specifically cancers of the oro and hypopharynx has to be promoted in developing countries. The annual (2014) estimate number of new Head and Neck cancers with locally advanced disease in India is around 140,000 and 91,000 (65%) patients do not receive the benefit of optimal treatment with ensuing poorer survival.

Background/Objectives: Cancers of the abdominal or pelvic organ rarely metastasize to the cervical lymph nodes. Although it indicates distant metastasis, perceivable prolongation of survival or cure may be possible in selected cases. We sought to identify patients with cervical metastasis from cancers below the diaphragm and identify patients who may benefit from aggressive treatment. Materials & Methods: From 2009 to 2017, patients with pathologically confirmed metastatic cervical lymph nodes originating from below the diaphragm were included for analysis. Patient demographics, cancer characteristics, treatment course, and clinical outcomes were analyzed. Results: 208 patients were identified. Left supraclavicular node (Virchow's node) was the most frequently involved. Irrespective of treatment, survival for uterine cervical and ovarian cancers was significantly longer than that of other primaries. Patients with isolated cervical metastasis (oligometastasis) had significantly longer median survival compared to patients with concomitant bone, lung, brain, and mediastinal metastases. Conclusion: Although cervical metastasis from cancers of the abdominal and pelvic organ represent distant metastasis, patients with uterine cervix and ovary primary and oligometastatic lesions may benefit from aggressive treatment. Prudent patient selection and further investigation is warranted.

It has become evident in recent years that parathyroid adenoma and well differentiated thyroid cancer occur together more than would be expected by chance alone. However, the association between them is not well understood. We have experienced 4 cases of coexistent parathyroid adenoma and well-differentiated thyroid cancer during the past 16 years. None of them had a familial incidence or a history of radiation exposure. Three cases showed symptomatic hypercalcemia(including renal stones, bone pain, joint pain) and in two of them(patient 1 and patient 2), thyroid abnormalities were detected preoperatively by neck ultrasonography or neck CT for evaluation of parathyroid lesions. However, in patient 3, a parathyoid humor was identified and removed incidentally during the course of thyroidectomy. In 3 cases, surgeries for thyroid carcinoma and parathyroid adenoma were performed during the same exploration of the neck, but in patient 4, thyroidectomy preceded parathyroidectomy; The interval between thyroidectomy and subsequent parathyroidectomy was 11 yeras. The thyroid tumors in 3 cases were papillary carcinoma, the sizes of which ranged from 1.0 cm to 1.5 cm in greatest diameter. The remaining case(patient 4) was minimal invasive follicular carcinoma. Total or near-total thyroidectomy with various types of cervical lymphnode dissection and bilateral neck exploration for the parathyroid lesion was performed in 3 cases with papillary carcinoma. Ipsilateral lobectomy and contralateral partial thyroidectomy with consequent unilateral neck exploration for the parathyroid tumor was performed in the case of follicular cancer. In our experience, parathyroid adenoma and well-differentiated thyroid carcinomas can be coexistent and we felt that the attention to the hypercalcemic patients would be needed for detection of this rare condition.

Tracheostomy and endotracheal intubation are often performed in patients with acute and chronic respiratory failure. Recently, the incidence of iatrogenic tracheal stenosis has increased. Tracheal resection and end-to-end anastomosis would be one of the most physiologic treatment options for severe tracheal stenosis. Also, this treatment can be applied to the management of trachea invaded by thyroid cancer and tracheal neoplasm. The authors aimed to analyze the outcomes of end-to-end anastomosis of trachea following segmental resection in tracheal stenosis and tracheal invasion of cancer that we have recently experienced. Materials and methods Authors retrospectively studied 19 cases treated by tracheal resection with end-to-end anastomosis between Feburuary 1996 and January 2003. 12 patients had tracheal stenosis, 6 patients had tracheal invasion by thryroid cancer and 1 patient had tracheal cancer. We analyzed the direct causes of tracheal stenosis, preoperative vocal cord function, operation technique, early and delayed postoperative complications, and the outcome of end-to-end anastomois. Result Decannulation without significant aspiration was achieved in 16 cases($89.5\%$). A 27 year-old man could not be decannulated because of restenosis. A 62 year-old woman could not be decannulated because of bilateral vocal cord palsy. Conclusion End-to-end anastomosis is a safe and effective surgical method for tracheal stenosis. Case selection for end-to-end anastomosis and preservation of recurrent laryngeal nerve during operation is very important.

A 65-year-old male visited hospital in the state of tracheostomal recurrence 1 year after total pharyngolaryngectomy. Extensive recurrence around stoma or paratracheal, superior mediastinal area is challenging in treatment, especially in securing airway. We performed mediastinal tracheotomy through resection of unilateral manubrium, some part of sternal side of clavicle and $1^{st}$ rib as the salvage operation for recurrent laryngeal cancer. This procedure could be risky, thus very careful patient selection is required because of a tortuous postoperative course. We would like to present the case that anterior mediastinal tracheostomy could be needed as appropriate palliative means of airway construction in the patients with recurrent laryngeal cancer with lower neck extension with literature review.

A 38-year-old man visited the hospital for a voice change that began two months previously. There were no other accompanying symptoms; the patient had a history of 20 years of smoking. Carbon dioxide (CO₂) laser cordectomy was performed on the left side of the vocal cord, and the biopsy results showed squamous cell carcinoma. Radiation therapy was not performed, and CO₂ laser cordectomy was performed again because of a recurrence of left vocal cord mass three years after a progress observation.

Neck mass is a common manifestation from head and neck malignancy, most of which come from mucosal squamous cell carcinomas in the upper aero-digestive tract. However, once aspiration cytology suggests atypical malignant cells in the neck mass rather than metastatic squamous cell carcinomas, it is confusing to decide the adequate diagnostic work-ups and treatment planning. Here, we report a 29-year-old woman presenting with a growing neck mass mimicking malignancy of unknown origin, which was finally diagnosed as primary lymphoepithelial carcinoma in the parotid gland with multiple metastases to the lymph nodes. The patient underwent comprehensive neck dissection and total parotidectomy and the adjuvant radiation treatment was given. Our report highlight that the primary salivary gland cancer should be considered as the potential tumor origin in case of malignancy of unknown origin in the head and neck region and neck mass suggestive of atypical carcinomas.

Multiple primary cancer is defined as the discrete primary cancers in an individual originating in different sites or tissues. Billroth, in 1869, first reported the occurrence of different primary malignant cancers in the same patient. Because early diagnosis and treatment are key to good survival and cure rates, clinicians should be more aware of the possibility of multiple primary cancers in an individual patient with malignant tumor. The authors recently experienced a case of fifth primary cancer, their sites of origin were lung, glottis, lymph node, supraglottis, common bile duct. We report this case with a brief review of literatures.

Background: Tongue cancer is still a major health problem in most developing countries around the world. Statistics shown the number of tongue cancers, especially in early age, to be increasing, with poor survival. Objective: To analyze the characteristic profile of tongue cancer patients in Indonesia as well as the survival rate. Materials and Methods: A cross sectional study was conducted in Dharmais National Cancer Hospital by collecting general, clinical, and survival data of tongue cancer patients from medical records for January 2009 to April 2012. Results: Tongue cancer incidence increased year by year. The average age of tongue cancer patients was 47.5 years, and males predominated, accounting for 64.5% of cases. Most patients presented at an advanced stage (69.6%). The histopathology type was squamous cell carcinoma in the vast majoriy (96.8%). The therapies applied were surgery (45.6%), radiation (63.6%) and chemotherapy (57.6%). The survival rate after one year is 60.6% and after two years was 12.1%. In addition, median survival of tongue cancer patients was 20 months (95% confidence interval 9.07-30.9). The significant factor affecting survival was size of tumor with a hazard ratio of 3.18 (95% CI, 1.02-9.93; p 0.046) for largest versus smallest categories. Conclusions: In each year, the number of tongue cancer incidents in Indonesia is increasing. The age of tongue cancer patients in Indonesia is younger compared to other countries. Moreover, the survival rates are not high.
