Granulosa cell tumors of the ovary are rare neoplasms that originate from sex-cord stromal cells. The long natural history of granulosa cell tumors and their tendency to recur years after the initial diagnosis are the most prominent of their characteristics. The secretion of estradiol is the reason for signs at presentation such as vaginal bleeding and precocious puberty. Abdominal pain and hemoperitoneum, which occasionally can occur, are attributable to tumor rupture. The most common finding in pelvic examination is a tumor mass, which is subsequently confirmed with imaging techniques. Surgery is the mainstay of initial management for histological diagnosis, appropriate staging, and debulking. A more conservative unilateral salpingo-oophorectomy is indicated in patients with stage I disease and patients of reproductive age. Total abdominal hysterectomy with bilateral salpingo-oophorectomy is the appropriate surgical treatment for postmenopausal women and those with more advanced disease. The stage of disease is the most important prognostic factor associated with the risk of relapse. There are no clear conclusions regarding the role of postoperative chemotherapy or radiotherapy in stage I disease and in those with completely resected tumor. The use of adjuvant chemotherapy or radiotherapy has sometimes been associated with prolonged disease-free survival and possibly overall survival. Chemotherapy is the treatment of choice for patients with advanced, recurrent, or metastatic disease, and BEP (bleomycin, etoposide, and cisplatin) is the preferred regimen. Although the overall rate of response to treatment is high, the impact of treatment on disease-free or overall survival is unknown. Prolonged surveillance is mandatory because tumors tend to recur years after the initial diagnosis.

Background Management of head and neck carcinoma from unknown primary (HNCUP) remains controversial, with neck dissection and radiotherapy (ND+RT) or definitive RT both commonly used. We aimed to characterize HNCUP and retrospectively compare outcomes for patients treated with ND+RT versus definitive RT. Methods From 1994-2009, 41 HNCUP patients underwent either ND+RT (n=22) or definitive RT+ concurrent chemotherapy (n=19) at our institution. Treatment outcomes were compared using Kaplan-Meier methods and log-rank test. Results There were no differences between patients treated with ND+RT and definitive RT in overall survival (OS), progression-free survival (PFS), or locoregional-relapse-free survival, freedom-from-locoregional failure, or freedom-from-distant failure. Among 17 ND+RT patients for whom human papillomavirus (HPV) status could be determined, HPV(+) patients trended towards improved OS (p=0.06)and PFS (p=0.15). Conclusions Neck dissection and post-op RT resulted in similar outcome as definitive RT. The prognostic implications of HPV(+) nodes in HNCUP are similar to those in oropharyngeal primary cancers.

Low-dose rate brachytherapy has become a mainstream treatment option for men diagnosed with prostate cancer because of excellent long-term treatment outcomes in low-, intermediate-, and high-risk patients. To a great extend due to patient lead advocacy for minimally invasive treatment options, high-quality prostate implants have become widely available in the US, Europe, and Japan. High-dose-rate (HDR) afterloading brachytherapy in the management of localised prostate cancer has practical, physical, and biological advantages over low-dose-rate seed brachytherapy. There are no free live sources used, no risk of source loss, and since the implant is a temporary procedure following discharge no issues with regard to radioprotection use of existing facilities exist. Patients with localized prostate cancer may benefit from high-dose-rate brachytherapy, which may be used alone in certain circumstances or in combination with external-beam radiotherapy in other settings. The purpose of this paper is to present the essentials of brachytherapies techniques along with the most important studies that support their effectiveness in the treatment of prostate cancer.

The majority of cancer patients will receive radiation therapy treatment at some stage during their malignancy. An acute skin reaction represents a common post radiation side effect with different grade of severity. In order to investigate the optimal methods to prevent and manage acute skin reactions related to radiation therapy we have conducted a systematic review on this topic. It seems that skin washing, including gentle washing with water alone with or without mild soap, should be permitted in patients receiving radiation therapy, to prevent acute skin reaction. In addition, a low dose (i.e., 1%) corticosteroid cream may be beneficial in the reduction of itching and irritation. We have concluded that there is insufficient evidence to support or refute specific topical or oral agents for the prevention or management of acute skin reaction. There is a need for further research to review treatments that have produced promising results in the reviewed research studies and to evaluate other commonly recommended topical treatments. The purpose of this patent and literature review is to advocate the current management of acute skin reaction.

Capecitabine (Xeloda®) was developed as a pro-drug of fluorouracil (FU), with the aim of improving tolerability and intratumor drug concentrations through its tumor-specific conversion to the active drug. The purpose of this paper is to review the available information on capecitabine, focusing on its clinical effectiveness against various carcinomas. Identification of all eligible English trails was made by searching the PubMed and Cochrane databases from 1980 to 2007. Search terms included capecitabine, Xeloda and cancer treatment. Nowadays, FDA has approved the use of capecitabine as a first line therapy in patients with metastatic colorectal cancer when single-agent fluoropyrimidine is preferred. The drug is also approved for use as a single agent in metastatic breast cancer patients who are resistant to both anthracycline and paclitaxel-based regimens or when further anthracycline treatment is contraindicated. It is also approved in combination with docetaxel after failure of prior anthracycline-based chemotherapy. In patients with prostate, pancreatic, renal cell and ovarian carcinomas, capecitabine as a single-agent or in combination with other drugs has also shown benefits. Improved tolerability and comparable efficacy, compared with the intravenous FU/LV combination, in addition to its oral administration, make capecitabine an attractive option for the treatment of several types of carcinomas.

During the last decade, the development of new drugs known as targeted therapies was the result of a better understanding of the processes involved in the transformation of normal cells into cancer. The term targeted therapy refers to drugs that selectively target specific molecular pathways involved in tumorigenesis or tumour progression. Angiogenesis is important for tumour growth and metastasis, and is an important target for new biological agents. Bevacizumab is a humanised recombinant antibody that prevents vascular endothelial growth factor (VEGF) receptor binding, and inhibits angiogenesis and tumour growth. On February 26, 2004, the Food and Drug Administration approved bevacizumab as first-line treatment for patients with metastatic colorectal cancer (CRC). The integration of targeted therapies in the treatment of colon cancer has resulted in significant improvements in efficacy outcomes. The efficacy of bevacizumab in the treatment of metastatic CRC is presented in this review article.

Ameloblastoma is known as a benign, slow-growing, rare, odontogenic neoplasm. The solid/multicystic, the unicystic with a fibrous connective-tissue capsule and the peripheral ameloblastoma represent the three well distinguished clinical types of ameloblastoma. Surgical resection with an attempt to achieve adequate free margins constitutes a well documented and accepted treatment modality. Controversies exist, however, with regard to the extent of operative intervention. Patients with inadequate or positive surgical margins or unresectable lesions can be treated with radiation or combined radiation and chemotherapy. The authors present a review of this sparse disease focusing on the special role and efficacy of radiation therapy in its management.

Patients with favourable prognostic parameters, such as localised disease without deep myometrial invasion, single polyp and embryonal histologic subtype, can effectively be treated by surgery. Patients with unfavourable prognostic parameters seem to benefit from a multimodality approach including surgery, adjuvant chemotherapy and RT.
