Malignant melanoma of the lacrimal sac is an exceptionally rare tumor with a poor prognosis. We report two cases of malignant melanoma of the lacrimal sac: a 73 year-old female treated with primary surgical resection and a 75 year-old male treated with surgical resection, adjuvant proton beam radiotherapy, and adjuvant immunotherapy. We discuss the role of post-operative proton beam therapy and recent advancements in immunotherapy. These cases highlight the importance of early diagnosis and multi-modality treatment in this aggressive malignancy. [ABSTRACT FROM AUTHOR]

Background: Endoscopic endonasal resection (EER) of sinonasal mucosal melanoma (SMM) is a newer surgical alternative to traditional external and/or open resection (OR). Studies on long-term outcomes are necessary to validate EER for this aggressive sinonasal malignancy. Objective: To compare outcomes of EER versus OR in SMM. Methods: A case series of patients who underwent surgical resection of SMM at a tertiary-care institution (2000 -2015) was studied retrospectively. Demographics, tumor site and stage, surgical approach, surgical margin status, local control, and survival were compared between those who underwent EER and OR. Results: Twenty-two patients met inclusion criteria. Nine underwent EER and 13 underwent OR. The mean age in the EER and OR groups was similar, 78.7 and 72.3 years, respectively. Two-thirds of patients were women (EER, 66.7%; OR, 61.5%). The nasal cavity was the most common primary tumor site (EER, 77.8%; OR, 84.6%). The local tumor stage in both groups was similar, with the majority of cases being T4 (EER, 55.6%; OR, 61.5%; p = 0.99). Negative margins were achieved in all EERs and in 69.2% of ORs. Median follow-up was 25.0 months for the overall group (range, 1.7-172.9 months), 32.6 months (range, 3.4 -58.7 months) for EER and 14.1 months (range, 1.7-172.9 months) for OR cohorts. The 5-year overall survival was statistically similar in both groups (EER, 53.3%; OR, 22.7%; p = 0.214) as was disease-free survival (EER, 55.6%; OR, 22.8%; p = 0.178). Local control, however, was significantly higher in the EER cohort (EER, 85.7%; OR, 37.6%; p = 0.026). Conclusion: In carefully selected patients with sinonasal melanoma, endoscopic surgery with an experienced team may offer comparable survival and improved local control over open surgery. Prospective, multicentered studies with larger cohorts are needed to validate these results. [ABSTRACT FROM AUTHOR]

Purpose: To report the outcomes of patients with favorable risk oropharyngeal cancer that underwent adjuvant radiation therapy with omission of the primary site from the clinical target volume (CTV). Material/Methods: A retrospective study of 40 patients treated with transoral surgery (TOS) followed by neck only radiation using intensity modulated radiation therapy (IMRT) with exclusion of the primary site. For all patients, a CTV of the primary surgical bed was contoured to obtain the estimated incidental dose to the primary site. Results: Median follow-up was 51 months (range, 13-155 months). The median radiation therapy (RT) dose to the neck was 6000 cGy (range, 5400-6400 cGy). The mean incidental dose to the primary tonsillar site was 4320 cGy (SD ± 480 cGy) and to the primary base of tongue site was 4060 cGy (SD ± 420 cGy). There were no local failures and only 1 regional failure, resulting in 97.5% locoregional control rate at 4 years. Two patients developed distant metastases, without evidence of locoregional recurrence, for a 4-year overall survival rate of 97%. Conclusions: Our analysis suggests that mucosal sparing RT after TOS in favorable risk oropharyngeal cancer patients may provide comparable oncologic and improved functional outcomes compared to conventional treatment in selected patients.

Objective: To report a single institutional series of high-grade neuroendocrine carcinoma of the larynx (NCL), a very rare yet aggressive tumor. To review the management of NCL, including discussion of clinical behavior, treatment outcome, and prognosis. Method: A retrospective chart review of high-grade laryngeal neuroendocrine carcinomas at a single institution, including small- and large-cell neuroendocrine carcinomas. A total of 8 patients with high-grade NCL treated at our institution from 1992 to 2014 were identified. Results: The median age at diagnosis was 65.5 years (range, 43-80). Five patients were male. Two patients had a known smoking history. Primary tumor location was supraglottic in 7 patients and glottic in 1 patient. Primary treatment consisted of surgery alone (3 patients), radiotherapy alone (1 patient), combination of chemotherapy and radiotherapy (1 patient), and surgery followed by postoperative chemoradiotherapy (3 patients). Locoregional recurrence followed by distant metastasis occurred in 6 patients. Median overall survival was 44.0 months (95% CI, 3-62.0). Conclusion: High-grade NCL is a rare diagnosis. Compared to well- and moderately differentiated NCL, high-grade NCL has a far more aggressive clinical course and associated with a worse prognosis. To our knowledge, this is the largest series of patients with high-grade NCL treated at a single institution. Prompt diagnosis and multimodality therapy including elective neck dissection may improve survival. [ABSTRACT FROM AUTHOR]

Objectives: We evaluated relapse patterns after transoral laser microsurgery (TLM) in squamous cell carcinoma (SCC) of the tonsil and tongue base and evaluated the indications for adjuvant irradiation. Methods: Between December 1, 1996, and December 31, 2005, 79 patients with previously untreated SCC of the tonsil or tongue base underwent TLM with or without neck dissection. Thirty-eight patients (48%) underwent postoperative irradiation (median, 62 Gy) to the primary site and the neck. Analysis of relapse patterns was performed on the basis of adverse risk factors and the presence or absence of adjuvant irradiation. Results: The median follow-up for living patients was 47 months (range, 10 to 107 months), and patients were monitored for at least 2 years or until recurrence or death. Local, regional, and distant treatment failures numbered 4, 6, and 4 for surgery alone (n = 41) and 0, 2, and 6 for adjuvant irradiation (n = 38), respectively. Patients with high-risk features (extracapsular extension or at least 2 adverse factors) had locoregional control rates at 2 or more years of 66% and 94% for TLM alone and TLM plus adjuvant irradiation, respectively. Conclusions: Adjuvant irradiation after TLM resection of oropharyngeal SCC with intermediate- or high-risk features improves locoregional control compared with TLM alone. [ABSTRACT FROM AUTHOR]

Research indicates that highly educated individuals endure hardships in finding suitable romantic partners. Romantic hardships affect social and emotional adjustment levels, leading to low self-efficacy in relationship decision making. To address the need for research pertaining to this topic, the authors explored the experiences of eight individuals purposively chosen. Conducting interviews based in qualitative methods, the authors discuss thematic patterns emerging from the study. Constraints such as lack of time and social outlets were barriers to meeting highly desirable mates. [ABSTRACT FROM AUTHOR]
