Three distinct outcomes in patients with colorectal adenocarcinoma and lymphovascular invasion: the good, the bad, and the ugly.

PURPOSE: In colorectal cancer (CRC), lymphovascular invasion (LVI) is a predictor of poor outcome and its analysis is nowadays recommended. Literature is still extremely heterogeneous, and we hypothesize that, within such a group of patients, there are any further predictors of survival. METHODS: A total of 2652 patients with I-III-stage CRC undergoing resection between 2002 and 2018 were included in a retrospective analysis of demographic, clinical, and histology with the aim of defining the impact of LVI on overall survival (OS) and its relationship with other prognostic factors. RESULTS: Overall, 5-year-OS was 62.6% (77-month-median survival). LVI was found in 558 (21%) specimens and resulted associated with 44.9%-5-year-OS (44 months) vs. 64.1% (104 months) of LVI cases. At multivariate analysis, LVI (p = 0.009), T3-4 (p < 0.001), and N ≠ 0 (p < 0.001) resulted independent predictors of outcome. LVI resulted as being associated with older age (p < 0.013), T3-4 (p < 0.001), lower grading (p < 0.001), N ≠ 0 (p < 0.001), mucinous histology (p < 0.001), budding (p < 0.001), and PNI (p < 0.001). Within the LVI + patients, T3-4 (p = 0.009) and N ≠ 0 (p < 0.001) resulted as independent predictors of shortened OS. In particular, N-status impacted the prognosis of patients with T3-4 tumors (p = 0.020), whereas it did not impact the prognosis of patients with T1-2 tumors (p = 0.393). Three groups (T1-2anyN, T3-4N0, T3-4 N ≠ 0), with distinct outcome (approximately 70%-, 52%-, and 35%-5-year-OS, respectively), were identified. CONCLUSIONS: LVI is associated with more aggressive/more advanced CRC and is confirmed as predictor of poor outcome. By using T- and N-stage, a simple algorithm may easily allow re-assessing the expected survival of patients with LVI + tumors.

The Holocaust Is a Significant and Independent Risk Factor of Late-Onset Cancers: A Systematic Review of the Literature and Original Data on Jewish Israeli, Jewish Non-Israeli and Non-Jewish Non-Israeli Survivors.

BACKGROUND/AIM: Seventy-six years after Auschwitz Liberation, the Holocaust keeps on persecuting its surviving victims. As witnessed by the psychiatric and medical literature in the last decades, in fact, the Holocaust survivors (HS) appear to suffer from several Shoah-related late-onset diseases impacting their survival, such as internal illnesses and post-traumatic stress disorder (PTSD). Cancer represents a further severe pathology which seems to be connected with the Holocaust experience. Our aim was to review the existing knowledge of Holocaust-related cancer in HS in order to assess its real incidence and clinicoprognostic significance. MATERIALS AND METHODS: We systematically reviewed the literature dealing with Israeli Jewish and non-Jewish non-Israeli HS developing cancer. We also reviewed and analyzed the cancer data of noted Jewish HS not resident or having resided in Israel available as public information. RESULTS: We found 16 and 15 studies on Israeli Jews and non-Jewish non-Israeli survivors, respectively. A statistically significant association between the Holocaust and development of late-onset cancer in HS was seen in most studies with cancer adversely impacting the survival. We also selected 330 noted Jewish non-Israeli HS: genocide-related late-onset cancer resulted to be a significant and independent risk factor of poor prognosis (p<0.0001) imparting shorter survival in affected versus non-cancer subjects (57 versus 64 years, respectively, p=0.0001). CONCLUSION: Although 76 years have passed, our review shows how the Holocaust keeps on burdening its survivors. Moreover, we offered the first analysis of Jewish HS not resident or having resided in Israel in terms of genocide-related late-onset diseases focusing on cancer. Further studies on Jewish non-Israeli HS are needed in order to corroborate our findings on late-onset cancer occurring in this targeted population.

Laparoscopic Partial Splenectomy: A Critical Appraisal of an Emerging Technique. A Review of the First 457 Published Cases.

Background: Laparoscopic partial splenectomy (LPS) may allow avoiding total splenectomy (TS) complications and maximizing the advantages of mini-invasive approach. The objective of this review is to assess feasibility and safety of LPS, to compare this approach with alternative options. Materials and Methods: A literature review of articles reporting LPS is performed. Several parameters, including age, indication, surgical technique, devices used for splenic section/hemostasis, adverse outcomes, including morbidity/mortality, conversions to open surgery, conversions to TS, operative time (OT), and hospital stay (HS), are analyzed. Articles comparing LPS' results with those of open partial splenectomy and laparoscopic TS are also analyzed. Results: Fifty-nine articles reporting 457 LPS were included. Patients' characteristics varied widely, concerning age and indications, including hematological disease (hereditary spherocytosis, drepanocytosis), splenic focal masses, and trauma. Several technical options are reported. Mean OT and HS are 128 ± 43.7 minutes and 4.9 ± 3.8 days, respectively. No mortality and 5.7% morbidity are reported. Conversion rates to open surgery and to TS are 3.9% and 3.7%, respectively. Conclusions: In conclusion LPS is feasible and safe, with no mortality, low morbidity, and low conversion rates to laparotomy and to TS. LPS may be accomplished by various techniques and tools. Major complications are sporadically reported, thus potential risks should not be underestimated.

Inguinal GIST: A Systematic Literature Review of Primary and Metastatic Cases.

BACKGROUND/AIM: Gastrointestinal stromal tumor (GIST) has a wide spectrum of clinical manifestations. Involvement of the groin region can cause interesting presentations but, as of 2020, has rarely been investigated. Our aim was to assess the clinicopathological and prognostic features of GIST appearing in this specific part of the body. MATERIALS AND METHODS: We investigated the world literature dealing with primary or metastatic GIST appearing in the inguinal region (IGIST). A case of metastatic IGIST from our clinical records was also included. RESULTS: We found only six cases of primary and nine of metastatic IGIST. All were of male gender, and most aged 60 years or more (10 cases). Inguinal hernia (11 cases) was the patient type most frequently affected. The association between metastatic IGIST and inguinal lymphadenopathy was statistically significant (p=0.049). CONCLUSION: IGIST is a rare entity with particular clinical manifestations. Inguinal hernia and inguinal lymphadenopathy should be carefully investigated in patients with a history of GIST.

Rapidly fatal outcome of Covid-19 after successful emergency surgery during pandemic outbreak in Northern Italy.

INTRODUCTION: A pandemic outbreak of novel coronavirus, named SARS-CoV-2 and responsible of Coronavirus Disease 2019 (COVID-19), has rapidly spread from China to Europe, being Northern Italy the first focus outside Asia. Little is known about the evolution of SARS-CoV-2 infection in patients undergoing surgery. PRESENTATION OF CASE: Here we report the first confirmed case of early postoperative SARS-CoV-2 infection in a patient recovering after Hartmann's procedure for acute diverticulitis. After an otherwise unevenful postoperative course, on post-operative day 8, the patient suddenly presented hyperpyrexia and cough, rapidly evolving to respiratory failure and death 36 h after symptoms onset. CT-scan identified bilateral, diffuse, interstitial pneumonitis and oropharyngeal swab test confirmed the presence of SARS-CoV-2. A previous contact with the partner, developing the same symptoms, remained unrecognized until ICU admission. DISCUSSION: During a pandemic outbreak, the early identification of SARS-CoV-2 infection of an inside patient initially considered to be infection-free has a pivotal importance not only for the prompt patient's management, but also to avoid infection spreading to other patients and hospital personnel.In the reported case, a more precise information to the patient regarding the imperative necessity to inform the medical personnel of any person of his entourage presenting, at any time, any tell-tale sign, symptom or examination which may be attributed to COVID-19, may have had allowed to anticipate patient's isolation and examinations and procedures aimed at identifying such an infection. CONCLUSION: Persistent hyperleucocytosis and increased CRP serum level in spite of uneventful postoperative course were the only, aspecific markers of an ongoing SARS-CoV-2 infection before symptoms' onset, and should be considered in future clinical practice in order to adopt the prompt and appropriate patient management and limit COVID-19 contagion in surgical units.
