Abstract The prognostic value of prostate-specific antigen (PSA) kinetics in primary high-volume metastatic hormone-sensitive prostate cancer (mHSPC) patients treated with novel hormonal therapy agents is still unclear. Here, we retrospectively reviewed the data of 102 patients with primary high-volume mHSPC who received novel hormonal therapy agents. The median follow-up was 32.25 ± 14.51 months and the median nadir PSA (nPSA) was 0.20 (0.06, 11.71) ng/mL after treatment. The mean time to nPSA was 10.82 ± 7.27 months and 55 patients (53.9%) had a PSA-density (PSA-D) ≤ 0.08 at 3-months. Univariate and multivariate Cox regression analyses showed that the absence of visceral metastases, nPSA ≤ 0.2 and PSA-D ≤ 0.08 were independent prognostic factors for better PFS and OS (all P

Abstract Malignant melanoma is a difficult-to-treat skin cancer with increasing incidence worldwide. Although type-I interferon (IFN) is no longer part of guidelines, several melanoma patients are treated with type-I interferon (IFN) at some point of the disease, potentially affecting its genetic progression. We run genome-wide copy number variation (CNV) analysis on previously type-I IFN-treated (n = 17) and control (n = 11) visceral metastases of melanoma patients. Results were completed with data from the TCGA and MM500 databases. We identified metastasis- and brain metastasis-specific gene signatures mostly affected by CN gains. Some cases were genetically resistant to IFN showing characteristic gene alterations (e.g. ABCA4 or ZEB2 gain and alterations of DNA repair genes). Analysis of a previously identified type-I IFN resistance gene set indicates that only a proportion of these genes was exclusive for the IFN-treated metastases reflecting a possible selective genomic pressure of endogenous IFNs during progression. Our data suggest that previous type-I IFN treatment and/or endogenous IFN production by immune response affect genomic progression of melanoma which may have clinical relevance, potentially influence immune checkpoint regulation in the tumor microenvironment.

Background: Tumor-infiltrating lymphocytes (TILs) were found to be associated with a better clinical outcome in specific subtypes of breast cancer. Aim: To study the association between TILs and the prognosis of Egyptian patients with HER2-negative breast cancer metastatic to the viscera. Methods: This prospective study included 100 patients with HER2-negative metastatic breast cancer. Intratumoral TILs, stromal TILs, and CD4 and CD8 were examined in the pathological specimens and their relationship with survival and response to treatment was studied. Results: At a median follow-up period of 43 months, the median overall survival was 44.7 months (95%CI: 39.2-50.2) and the 5-year overall survival rate was 28%. A high level of CD8+ve TILs was associated with significantly longer overall survival (p < 0.001) and progression-free survival (p=0.043). There was no significant correlation between intratumoral TILs, stromal TILs, or CD4+ve and overall survival. Conclusions: A higher level of CD8+ve TILs is associated with better overall as well as progression-free survival in HER2-negative breast cancer with visceral metastases.

Abstract Background To evaluate the anatomic site(s) of initial disease progression in patients with castration resistant metastatic prostate cancer (mCRPC) in the presence or absence of pre-treatment visceral metastases while on systemic therapy. Methods This is a retrospective cohort study of mCRPC patients who have baseline and at least one follow up bone scan and CT chest, abdomen and pelvis (CAP). Disease progression was determined by RECIST and/or ≥ 30% increase in automated bone scan lesion area score. Kaplan–Meier plot was used to estimate the median progression free survival and log-rank tests were used to compare anatomic sites. Results Of 203 patients, 61 (30%) had pre-treatment visceral metastases. Patients with baseline visceral disease were 1.5 times more likely to develop disease progression (HR = 1.53; 95% CI, 1.03–2.26). Disease progression was a result of worsening bone scan disease (42% (16/38)) versus visceral (32% (12/38)) or lymph node disease (3% (1/38)) by CT or a combination thereof (23% (9/38)). Median time to progression (TTP) did not differ by anatomic location of initial progression (p = 0.86). Development of new lesions occurred in 50% of those visceral patients with soft tissue only progression and was associated with a significantly longer TTP (3.1 months (2.8–4.3 months) than those with worsening of pre-existing lesions (1.8 months (1.6–2.7 months); p = 0.04. Conclusions Patients with pre-treatment visceral metastases in mCRPC are more likely to experience disease progression of bone disease with the initial anatomic site of progression similar to those without baseline visceral involvement.

The article reviews studies evaluating the efficacy and safety of eribulin chemotherapy in patients with HER2-negative advanced breast cancer. It analyzes the results derived from large randomized studies, highlights the main advantages peculiar to eribulin, and describes the key mechanisms of the antitumor activity displayed by the drug. Among those presented, there are significant retrospective studies evaluating the role of eribulin chemotherapy in late and early advanced breast cancer treatment lines, as well as an analysis of surveys aimed to evaluate the efficacy of the drug in various clinical settings (for visceral metastases, brain lesion, and in elderly patients). This article reflects the main results of Russian population analyses evaluating the efficacy and safety of eribulin chemotherapy in routine clinical practice.

Abstract Background Endocrine therapy is the preferred treatment for patients with hormone receptor ‐positive metastatic breast cancer (MBC). While visceral metastasis is a negative prognostic factor, few studies have distinguished between the prognoses of patients with metastases at different visceral sites. Patients and methods In total, 398 patients receiving fulvestrant 500 mg at a single center over a 6‐year period were analyzed. Logistic regression models were used to identify the prognostic factors associated with progression‐free survival (PFS). Kaplan‐Meier analysis was used to compare the PFS of patients with lung and liver metastases. Results Baseline visceral metastases were present in 233 patients, including 138 with lungw/o liver metastases (lung metastases without liver involvement), 51 with liverw/o lung metastases (liver metastases without lung involvement) and 41 with lung and liver metastases. The median PFS was 6.8 months (5.6 and 9.2 months for visceral and nonvisceral metastases, respectively, P = .028). PFS was longer in patients with lungw/o liver metastases than in those with liverw/o lung metastases or lung and liver metastases (9.6, 3.7 and 3.2 months, respectively, P

Clear cell renal cell carcinoma (ccRCC) usually spreads in the spinal region causing instability or spinal cord compression leading to neurological deficits. Therefore, surgical treatment is required for improving the outcome of patients. The aim of this study is to identify which prognostic factors could affect overall survival in patients affected by ccRCC. Methods: Retrospective cohort study of patients with ccRCC spinal metastases, surgically treated from November 2009 to April 2019. Demographic and clinical data were collected. The Kaplan–Meier method was used to estimate overall survival, and the log-rank test was used to evaluate differences in survival among potentially prognostic factors. Results: A total of 69 patients were surgically treated and followed up for a median period of 65 months. The average age at the time of surgery was 62.6 years old. The median overall survival (OS) was 34.7 months (95% CI 20.8–51.9) and 5-year OS was 31.2% (95% CI 19.2–44.1). A high Tokuhashi score (p = 0.0217), the presence of visceral metastases (p < 0.001), other bone metastases (p = 0.02012) and the kind of surgical treatment (p = 0.0395) are the main prognostic factors that influence the OS. Moreover, 3-year progression-free survival (PFS) was analyzed: the median PFS was 53.1 months and the % 3-year PFS was 62.9% (45.2–76.3). In the multivariate analysis, only pre-operative radiation therapy had a significant impact on 3-year PFS (95% CI 0.929–12.994, p = 0.0643). Conclusion: The results of this study suggest that the absence of visceral metastases and an aggressive surgery as en-bloc, when feasible, could prolong the survival rate and improve quality of life for patients.

Cutaneous metastasis from solid tumors is a rare event and usually represents a late occurrence in the natural history of an advanced visceral malignancy. Rarely, cutaneous metastasis has been described in colorectal cancer patients. The most frequent cutaneous site of colorectal metastasis is the surgical scar in the abdomen following the removal of the primary malignancy, followed by the extremities, perineum, head, neck, and penis. Metastases to the thigh and back of the trunk are anecdotical. Dermatological diagnosis of cutaneous metastasis can be quite complex, especially in unusual sites, such as in the facial skin or thorax and in cases of single cutaneous lesions since metastasis from colorectal cancer is not usually the first clinical hypothesis, leading to misdiagnosis. To date, due to the rarity of cutaneous metastasis from colorectal cancer, little evidence, most of which is based on case reports and very small case series, is currently available. Therefore, a better understanding of the clinic-pathological characteristics of this unusual metastatic site represents an unmet clinical need. We present a large series of 29 cutaneous metastases from colorectal cancer with particular concerns regarding anatomic localization and the time of onset with respect to primitive colorectal cancer and visceral metastases.
