Colonoscopic-Assisted Laparoscopic Wedge Resection for Colonic Lesions: A Prospective Multicenter Cohort Study (LIMERIC-Study).

OBJECTIVE: The aim of this study was to evaluate the safety and efficacy of a modified CAL-WR. SUMMARY BACKGROUND DATA: The use of segmental colectomy in patients with endoscopically unresectable colonic lesions results in significant morbidity and mortality. CAL-WR is an alternative procedure that may reduce morbidity. METHODS: This prospective multicenter study was performed in 13 Dutch hospitals between January 2017 and December 2019. Inclusion criteria were (1) colonic lesions inaccessible using current endoscopic resection techniques (judged by an expert panel), (2) non-lifting residual/recurrent adenomatous tissue after previous polypectomy or (3) an undetermined resection margin after endoscopic removal of a low-risk pathological T1 (pT1) colon carcinoma. Thirty-day morbidity, technical success rate and radicality were evaluated. RESULTS: Of the 118 patients included (56% male, mean age 66 years, standard deviation ± 8 years), 66 (56%) had complex lesions unsuitable for endoscopic removal, 34 (29%) had non-lifting residual/recurrent adenoma after previous polypectomy and 18 (15%) had uncertain resection margins after polypectomy of a pT1 colon carcinoma. CAL-WR was technically successful in 93% and R0 resection was achieved in 91% of patients. Minor complications (Clavien-Dindo i-ii) were noted in 7 patients (6%) and an additional oncologic segmental resection was performed in 12 cases (11%). Residual tissue at the scar was observed in 5% of patients during endoscopic follow-up. CONCLUSIONS: CAL-WR is an effective, organ-preserving approach that results in minor complications and circumvents the need for major surgery. CAL-WR, therefore, deserves consideration when endoscopic excision of circumscribed lesions is impossible or incomplete.

Management of a Unique Sinonasal Undifferentiated Carcinoma Subtype in the Era of SARS-CoV-2.

The novel coronavirus (SARS-CoV-2) pandemic has influenced the timeliness of care for patients with both common and rare conditions, particularly those affecting high-risk operative sites such as the upper aerodigestive tract. Sinonasal undifferentiated carcinoma (SNUC) represents a rare malignancy of the sinonasal tract, a unique subset of which has never been previously reported in the otolaryngology literature and is characterized by inactivation of the SMARCB (INI-1) tumor suppressor gene. This subtype exhibits a particularly poor prognosis and is characterized pathologically by its rhabdoid appearance. Here we present the case of an individual who was diagnosed with a sinonasal mass during the SARS-CoV-2 pandemic, which was ultimately found to be SMARCB (INI-1)-deficient sinonasal carcinoma. Advanced imaging was deferred in the interest of limiting the patient's exposure to the virus, and expedited operative management was performed which facilitated prompt referral for adjuvant chemoradiation. The SARS-CoV-2 pandemic presents unique challenges, but the work-up of high-risk lesions must be prioritized; this continues to be paramount as SARS-CoV-2 resurges in many cities across the USA.

Tor Vergata University-Hospital in the Beginning of COVID-19-Era: Experience and Recommendation for Breast Cancer Patients.

COVID-19 has been officially declared as a pandemic by the WHO. Italy was the first European country to be strongly affected by this outbreak. All elective and health promotion activities were reduced. Accordingly, Italian Breast Units and breast cancer (BC) screening programs scaled down significantly their activities. The aim of this study was to evaluate measures that could potentially reduce the clinical impact of COVID-19 on BC patients. Temporary recommendations are needed that could assist specialists in preventing COVID-19 infection and optimizing resources for diagnosis and treatment of BC patients.

Breast Cancer Surgery During the COVID-19 Pandemic: An Observational Clinical Study of the Breast Surgery Clinic at Ospedale Policlinico San Martino - Genoa, Italy.

BACKGROUND: COVID-19 pandemic required a marked re-allocation of healthcare resources, including at Breast Units. A patient-tailored program was developed to assess its efficacy regarding prevention of COVID-19 infection among patients with breast cancer undergoing surgery and healthcare workers (HCWs). PATIENTS AND METHODS: From March 9th to April 9th 2020, 91 patients were selected for elective surgery by means of: i) Pre-hospital screening aimed at avoiding hospitalization of symptomatic or suspicious COVID-19 patients, and ii) prioritisation of surgical procedure according to specific disease features. RESULTS: Eighty-five patients (93.4%) were fit for surgery, while five patients (5.5%) were temporarily excluded through 'telephone triage'; another two patients were excluded at in-hospital triage. A total of 71 out of 85 patients (83.5%) were diagnosed with invasive cancer, most of whom were undergoing breast-conserving surgery (61 out of 85 patients, 71.8%). The mean in-hospital stay was 2.2 days (SD=0.7 days). After hospital discharge, no patient needed re-admission due to post-operative complications; moreover, no COVID-19 infection among patients or HCWs was detected. CONCLUSION: Safe breast cancer surgery was accomplished for both patients and HCWs by means of a careful preoperative selection of patients and in-hospital preventative measures. This screening program can be transferred to high-volume Breast Units and it may be useful in implementing European Community recommendations for prevention of COVID-19 infection.
