The surgical treatment of non-metastatic melanoma in a Clinical National Melanoma Registry Study Group (CNMR): a retrospective cohort quality improvement study to reduce the morbidity rates

Background: Reproducible, high-quality surgery is a key point in the management of cancer patients. Quality indicators for surgical treatment of melanoma has been presented with benchmarks but data on morbidity are still limited. This study presents the quality indicators on morbidity after surgical treatment for non-metastatic skin melanoma in an Italian registry. Methods: Data were extracted from the Central National Melanoma Registry (CNMR) promoted by the Italian Melanoma Intergroup (IMI). All surgical procedures (WE, SNLB or LFND) for non-metastatic skin melanoma between January 2011 and February 2017 were evaluated for inclusion in the study. Only centers with adequate completeness of information (> 80%) were included in the study. Short-term complications (wound infection, dehiscence, skin graft failure and seroma) were investigated. Results: Wound infection rate was 1.1% (0.4 to 2.7%) in WE, 1.3% (0.7 to 2.5%) in SLNB and 4.1% (2.1 to 8.0%) in LFND. Wound dehiscence rate was 2.0% (0.8 to 5.1%) in WE, 0.9% (0.2 to 3.0%) in SLNB and 2.8% (0.9 to 8.6%) in LFND. Seroma rate was 4.2% (1.5 to 11.1%) in SLNB and 15.1% (4.6 to 39.9%) in LFND. Unreliable information was found on skin graft failure. Conclusions: Our findings contribute to available literature in setting up the recommended standards for melanoma centers, thus improving the quality of surgery offered to patients. A consensus on the core issues around surgical morbidity is needed to provide practical guidance on morbidity prevention and management

Unusual Fatal Outcome Following Administration of a Combination of anti-PD1 and anti-CTLA4 in Metastatic Renal Cell Carcinoma: Liver Toxicity Case Report and a Literature Review

Hepatic dysfunction, in the absence of liver metastases, occurs in 10–15% of renal cell carcinoma (RCC) patients, while immune hepatitis due to anti-CTLA4 and anti-PD1 administration affects about 3–9% and 0.7–1.8% of treated patients, respectively. Liver toxicity following combination therapy (anti-CTLA4 and anti-PD1) is seen in 29% of patients overall and grade 3–4 toxicity in 14% of patients. Stauffer’s syndrome is a rare para-neoplastic phenomenon associated with RCC and characterized by abnormal liver function tests, hepato-splenomegaly and histological changes consistent with non-specific hepatitis. We describe a case of RCC treated with anti-CTLA4 and anti-PD1 therapy resulting in immediate liver toxicity and death after 2 months of progressive hepatic impairment. We hypothesize that high IL-6 levels due to Stauffer’s syndrome might have contributed to immune-related hepatic failure

Epigenetic inactivation implies independent functions for insulin-like growth factor binding protein (IGFBP)-related protein 1 and the related IGFBPL1 in inhibiting breast cancer phenotypes

Purpose: To analyze epigenetic regulation of two related genes, insulin-like growth factor binding protein-related protein 1 (IGFBP-rP1) and IGFBPL1, and its significance as a determinant of clinical phenotypes in human breast cancer. Experimental Design: We have investigated the expression and epigenetic regulation of IGFBP-rP1 and IGFBPL1 in human breast cancer cell lines and primary and metastatic carcinomas. Results: Expression of IGFBP-rP1 and IGFBPL1 is down-regulated in breast cancer cell lines. Aberrant methylation in the CpG islands of each gene correlates well with loss of expression at the mRNA level. Analysis of methylation in DNA isolated from human primary breast tumors showed that methylation in either gene was associated with a worse overall survival (OS; P = 0.008) and disease-free survival (DFS) following surgery (P = 0.04) and worse DFS following adjuvant chemotherapy (P = 0.01). Methylation of IGFBP-rP1 alone was associated with a trend toward decreased OS (P = 0.10) and decreased DFS (P = 0.25). Methylation in IGFBPL1 was clearly associated with worse OS (P = 0.001) and DFS (P < 0.0001). Methylation in either IGFBP-rP1 or IGFBPL1 was significantly associated with nodal disease (P < 0.001). Conclusions: Expression of IGFBP-rP1 and IGFBPL1 is regulated by aberrant hypermethylation in breast cancer, implying that inactivation of these genes is involved in the pathogenesis of this malignancy. Analysis of methylation of these genes may have utility in prediction of clinical phenotypes, such as nodal disease and response to chemotherapy

How Chemotherapy Affects the Tumor Immune Microenvironment: A Narrative Review

Chemotherapy is much more effective in immunocompetent mice than in immunodeficient ones, and it is now acknowledged that an efficient immune system is necessary to optimize chemotherapy activity and efficacy. Furthermore, chemotherapy itself may reinvigorate immune response in different ways: by targeting cancer cells through the induction of cell stress, the release of damage signals and the induction of immunogenic cell death, by targeting immune cells, inhibiting immune suppressive cells and/or activating immune effector cells; and by targeting the host physiology through changes in the balance of gut microbiome. All these effects acting on immune and non-immune components interfere with the tumor microenvironment, leading to the different activity and efficacy of treatments. This article describes the correlation between chemotherapy and the immune changes induced in the tumor microenvironment. Our ultimate aim is to pave the way for the identification of the best drugs or combinations, the doses, the schedules and the right sequences to use when chemotherapy is combined with immunotherapy

Patients with cancer and hospital admissions: Disease trajectory and strategic choices

Objectives: Hospital admission (HA) in cancer history is a common, repeated and frequently unplanned event. The emergency departments (EDs) and the oncological outpatient service (OOS) are the ordinary way of entry. We studied the reasons of admission, pathways of access and discharge and prognostic factors in a population of admitted patients with cancer. Methods: The health records of the admitted patients in the oncological ward of a referral hospital in a 6-month period were retrieved and analysed. The characteristics of those admitted in the last 3 months of life were compared with the other group. Results: Among the 147 HA, 79.5% were unplanned, 48.9% passing through the ED and 30.6% through the OOS; 56.5% were due to cancer-related symptoms; 50.3% occurred in the last 3 months of life. Median overall survival was 90 days (95% IC 53.1-126.9). Independent prognostic factors for survival were: being admitted for symptoms, referral through the ED and not being discharged at home. Conclusions: Hospital is a turning point in the cancer care pathway. Patients needing HA have a dismal prognosis, half of them being in the last 3 months of life. This group can be identified using universally available variables
