Prevention and Management of Complications from Esophagectomy

While surgery plays a major role in the treatment and potential cure of esophageal cancer, esophagectomy continues to have a significant amount of morbidity compared to other surgical oncology procedures. Efforts to improve morbidity and mortality from esophagectomy include the Consensus Guidelines for Complications from Esophagectomies, Enhanced Recovery after Surgery protocols as well as others. Although we strive to improve morbidity and mortality after these surgeries, adverse events still occur. They affect not only patient quality of life and increase cost of care for esophageal cancer but also have a negative impact on overall cancer survival. This chapter reviews the prevention of adverse outcomes from esophagectomies as well as discusses the management of many complications that may occur more common to the operation

Giant Intraperitoneal Multiloculated Pseudocyst in a Male.

Intraperitoneal pseudocysts are rare and may be difficult to differentiate from other malignant neoplasms. Reports of occurrences are mainly associated with long-term intraperitoneal catheter use, intraperitoneal catheter infections, or major pelvic surgery in females, although there are few reported incidences without prior trauma. We present a case of a male patient found to have a 19 × 15 × 9 cm intraperitoneal pseudocyst with other multiloculated areas and a history of a right inguinal hernia repair. After a thorough review of the literature, this is the first multiloculated nonpancreatic pseudocyst reported in a male patient

The role of radiation therapy in melanoma.

Although melanoma was historically thought to be radiation resistant, there are limited data to support the use of adjuvant radiation therapy for certain situations at increased risk for locoregional recurrence. High-risk primary tumor features include thickness, ulceration, certain anatomic locations, satellitosis, desmoplastic/neurotropic features, and head and neck mucosal and anorectal melanoma. Lentigo maligna can be effectively treated with either adjuvant or definitive radiation therapy. Some retrospective and prospective randomized studies support the use of adjuvant radiation to improve regional control after lymph node dissection for high-risk nodal metastatic disease. Consensus on the optimal radiation doses and fractionation is lacking

Ablative Therapies for Colorectal Polyps and Malignancy

Endoscopic techniques are gaining popularity in the management of colorectal polyps and occasionally superficial cancers. While their use is in many times palliative, they have proven to be curative in carefully selected patients with polyps or malignancies, with less morbidity than radical resection. However, one should note that data supporting local and ablative therapies for colorectal cancer is scarce and may be subject to publication bias. Therefore, for curative intent, these techniques should only be considered in highly select cases as higher rates of local recurrences have also been reported. The aim of this review is to explain the different modalities of local and ablative therapies specific to colorectal neoplasia and explain the indications and circumstances where they have been most successful

Primary Merkel cell carcinoma of the parotid gland.

Primary Merkel cell carcinoma (MCC) is a neuroendocrine tumor that typically affects older whites. It usually originates in the dermis, but in rare instances it has arisen in other primary sites, including the oral mucosa and the parotid gland. Explanations for the presence of MCC in these atypical locations have included theories of malignant transformation and neuroendocrine migration. We describe the case of a 35-year-old white woman who had an MCC in the parotid gland and no evidence of any other primary cutaneous lesion. A left superficial parotidectomy with facial nerve preservation was performed, and a histologic diagnosis of MCC was made. Positron-emission tomography was negative for other lesions, and postoperative radiation therapy was administered for local control. To the best of our knowledge, this is only the sixth case of a primary MCC of the parotid gland to be reported in the English-language literature; of these 6 patients, ours was by far the youngest. Otolaryngologists should be familiar with this rare but potentially fatal neoplasm

Metastatic adenocarcinoma of the pancreas presents as metastases to the axillary/supraclavicular region as the first sign of the disease.

Mucinous tumors of the pancreas are rare and the diagnosis of invasive carcinoma can be a dilemma. While metastatic disease from mucinous cystadenocarcinoma (MCAC) and invasive intraductal papillary mucinous neoplasms (IPMN) have been reported, no extraperitoneal mucinous cystic metastatic disease has been described. When metastatic, the overall survival rates for invasive adenocarcinoma, mucinous cystadenocarcinoma (MCAC) and invasive intraductal papillary mucinous neoplasms (IPMN) are similar. The best improvement in the overall and progression free survival has been demonstrated with FOLFIRINOX (folinic acid - fluorouracil - irinotecan - oxaliplatin) for metastatic adenocarcinoma and Gemcitabine based regimens for MCAC. However, the variable responses of metastatic mucinous lesions have been observed and the overall prognosis remains poor. We describe a case of a patient who presented with metastatic adenocarcinoma of the pancreas as cystic masses in the supraclavicular and axillary regions. Additionally, this patient was initially treated with FOLFIRINOX and continues to have stable primary and metastatic disease after 18 months from the diagnosis

Deep Margins Melanoma: How Deep Is Deep Enough?

BACKGROUND: Wide excision (WE) to muscular fascia for invasive melanoma is common practice but excision to subcutaneous tissue may be adequate. We evaluated practice patterns regarding depth of biopsy and excision as well as risks for recurrence. METHODS: Retrospective review of patients with pT1-4 melanoma (cN0) treated with WE at a single institution was performed. Patient factors were evaluated. Biopsy and excision techniques were compared to pathology and reviewed for recurrence. RESULTS: 385 patients from 2006 to 2020 were included. Lesions were on the extremity (n = 189), head/neck (n = 48), trunk (n = 148). Biopsy techniques included shave (n = 330), excisional (n = 36), punch (n = 10), incisional (n = 9). Deep biopsy margins were positive for IM/melanoma in situ in 139 patients. WE specimens were taken to muscular fascia (n = 218) or mid/deep fat (n = 144). 51 patients had recurrent disease or a new primary lesion: locoregional (n = 31), distant (3), or new lesions (n = 17). DISCUSSION: Patient characteristics associated with recurrence include older age and female gender. Tumor characteristics associated with recurrence include lesions located on the trunk, superficial spreading melanoma, ulceration, perineural invasion, and clinical T and P stage. Patients that recurred were more likely to have WE taken to or including muscular fascia. Biopsy type, deep margin on biopsy, and depth of dissection was not associated with recurrence

Adrenocortical carcinoma arising from an adrenal adenoma in a young adult female.

Adrenocortical carcinoma (ACC) is a rare malignancy that often carries a poor prognosis whereas adrenal incidentalomas are relatively common findings on imaging. Although most adrenal lesions are benign, 15% of patients with ACC are diagnosed based on workup for an adrenal incidentaloma. Continued surveillance or surgical resection may be recommended depending on size. The risk of a benign, non-functional adrenal lesion becoming malignant is low. Therefore, adrenal lesions typically undergo surveillance for no more than 2 years in patients with stable findings and no history of malignancy. This case describes a young adult female with a benign left adrenal adenoma who was found to have high grade ACC 7 years later. Based on interval size increase with indeterminate density, patient underwent surgical resection with adjuvant radiation and medical therapy
