The role of preoperative systemic treatment in patients with breast cancer.

The goal of preoperative pharmacotherapy in patients with breast cancer is to enable breast conserving surgery in stage T3N0-1M0 or radical mastectomy in patients with primary inoperative tumors (T1-4N0-3M0). The choice of optimal treatment should be based not only on risk factors resulting from the stage but also on predicted cancer responsiveness to the treatment. The breast cancer subtypes defined by immunohistochemical profile (expression of ER, PR, HER2 and Ki67) are characterized by different responsiveness to therapy. Complete response confirmed by histopathological evaluation after neoadjuvant chemotherapy is a positive prognostic factor in some breast cancer subtypes. This marker is not of value in postmenopausal patients with ER/PR+ HER2- tumors, who are candidates for neoadjuvant hormone therapy. These patients have a good prognosis if in a histopathological report after surgery there are features such as pT1, pN0, Ki67 < 3%, and ER Allred score ≥ 3. The goal of the paper is to present current knowledge about preoperative pharmacotherapy of breast cancer.

A retrospective evaluation of associations between chronic obstructive pulmonary disease, smoking, and efficacy of chemotherapy and selected laboratory parameters in patients with advanced non-small cell lung cancer.

AIM OF THE STUDY: To was to determine the impact of chronic obstructive pulmonary disease (COPD) and active smoking on the efficacy of chemotherapy and complete blood count (CBC) in patients with non-small cell lung cancer (NSCLC). MATERIAL AND METHODS: The retrospective evaluation included 50 patients with stage IIIB-IV NSCLC, who started cisplatin-based chemotherapy. Peripheral blood CBC values were collected for testing before chemotherapy and after the first and third cycles. RESULTS: COPD was diagnosed in 49% of patients, while 42% of those enrolled were current smokers. Current smoking (p = 0.92) and COPD (p = 0.91) status did not affect the response to treatment. The non-COPD population presented a significantly higher pretreatment absolute lymphocyte count (ALC) than the COPD population (2.31 vs. 1.81 × 109/l; p = 0.0374). Also, only the non-COPD group demonstrated an elevated absolute monocyte count (AMC) following the first and third cycles of chemotherapy (p = 0.004). In current smokers, pretreatment values for white blood cells (WBC), absolute neutrophil count (ANC), and platelets (PLT) were higher than in the ex-smoker population (WBC 9.94 vs. 8.7 (× 109/l); p = 0.01; ANC 6.47 vs. 5.61 (× 109/l); p = 0.037; PLT 316 vs. 266 (× 109/l); p = 0.049). Ex-smokers demonstrated AMC level elevation after the first cycle of chemotherapy and PLT level elevation after the third cycle, while current smokers also demonstrated an early decrease in LMR. CONCLUSIONS: COPD and smoking induce chronic systemic inflammation and oxidative stress, which influence the results of standard laboratory tests, but do not change the response rate of lung cancer on chemotherapy.

Lack of CD151/integrin α3ß1 complex is predictive of poor outcome in node-negative lobular breast carcinoma: opposing roles of CD151 in invasive lobular and ductal breast cancers.

BACKGROUND: The proposed involvement of CD151 in breast cancer (BCa) progression is based on findings from studies in invasive ductal carcinoma (IDC). The IDC and invasive lobular carcinoma (ILC) represent distinct disease entities. Here we evaluated clinical significance of CD151 alone and in association with integrin α3ß1 in patients with ILC in context of the data of our recent IDC study. METHODS: Expression of CD151 and/or integrin α3ß1 was evaluated in ILC samples (N=117) using immunohistochemistry. The findings were analysed in relation to our results from an IDC cohort (N=182) demonstrating a prognostic value of an expression of CD151/integrin α3ß1 complex in patients with HER2-negative tumours. RESULTS: Unlike in the IDCs, neither CD151 nor CD151/α3ß1 complex showed any correlation with any of the ILC characteristics. Lack of both CD151 and α3ß1 was significantly correlated with poor survival (P=0.034) in lymph node-negative ILC N(-) cases. The CD151(-)/α3ß1(-) patients had 3.12-fold higher risk of death from BCa in comparison with the rest of the ILC N(-) patients. CONCLUSIONS: Biological role of CD151/α3ß1 varies between ILC and IDC. Assessment of CD151/α3ß1 might help to identify ILC N(-) patients with increased risk of distant metastases.

Synchronous primary ovarian and endometrial cancers: a series of cases and a review of literature.

Synchronous cancers account for 0.7-1.8% of all gynecologic cancers. Among them, synchronous ovarian and endometrial cancers are predominant (40-53%). Patients with synchronous cancers have better prognosis than those with single disseminated cancer. We present 10 patients with synchronous ovarian and endometrial cancers who were treated at the Chemotherapy Department of the Medical University of Lodz in 2009-2013. The most often reported symptom of the disease was abnormal vaginal bleeding (6 patients). The range of the patients' age was 48-62 and the median age was 56. Five patients had stage I of ovarian cancer, single patients had stage IIA, IIB and IIIB, 2 patients had stage IIIC. Three patients had I, 5 - II, and 2 - III stage of endometrial cancer. All patients had endometrioid type of endometrial cancer, 7 of them had also the same histological type of ovarian cancer. All patients had adjuvant chemotherapy because of ovarian cancer, none of them had adjuvant radiotherapy. One patient was lost to follow up. For other patients a median follow up was 13 months (range: 3-53 months). One patient experienced relapse, all patients are alive. Synchronous ovarian and endometrial cancers are usually diagnosed at an earlier stage, have lower histological grade and better prognosis than single cancers. The most common histological type of both endometrial and ovarian cancers is endometrioid carcinoma. The first symptoms reported by our patients and the course of the disease were concordant with data from the literature.

Similar prevalence but different characteristics of pain in kidney transplant recipients and chronic hemodialysis patients.

BACKGROUND: Chronic pain is frequent in both hemodialysis (HD) patients and kidney transplant (KTx) recipients but its detailed characteristics have never been thoroughly investigated. AIM: To compare prevalence of pain, its locations and characteristics, and analgesics use in chronic HD and KTx patients. METHODS: A cross-sectional comparative study in 164 HD patients and 114 stable deceased donor KTx recipients. All participants completed the modified McGill Pain Questionnaire. RESULTS: Overall, 63% of HD patients and 62% of KTx patients reported pain. Fifty-four percent of HD patients and 67% of KTx patients indicated more than one location of pain. Severe pain was more common in HD patients, and prevalence of pain-associated symptoms from major body systems was higher in HD patients. Pain in both groups was mostly local, paroxysmal and/or chronic. Fifteen percent of HD patients and 37% of KTx patients with chronic pain were not receiving pain relief drugs. The general feeling of illness was lower in KTx than HD patients (4.54 ± 2.1 vs. 5.6 ± 0.7; p < 0.0001); however, in the former group, it was systematically increasing with the time after transplantation. CONCLUSIONS: A successful kidney transplantation does not lead to a significant reduction in the prevalence of pain when compared to chronic HD patients. Pain relief medications are underused in KTx patients.

Cardiovascular risk factors among cancer patients qualified for systemic treatment. Analysis of a cardiovascular disease-free cohort from the Polish multicentre study ONCOECHO.

INTRODUCTION: Cancer therapies are currently more efficient at increasing the survival of patients (pts) with cancer. Unfortunately, the cardiovascular (CV) complications of cancer therapies may adversely affect improving results of treatment. The aim of the study was to evaluate the prevalence of classical CV risk factors among pts with de novo diagnosis of cancer and thus identify the cohort of pts with potentially increased future risk of CV complications. MATERIAL AND METHODS: The analysis is based on the database of the multicentre ONCOECHO study. Pts before systemic treatment (chemotherapy or targeted therapy) were included. The diagnostic datasets of resting electrocardiogram, blood samples, and transthoracic echocardiogram were analysed in 343 consecutive pts who were free from any cardiovascular disease that could adversely affect the introduced treatment. RESULTS: Our cohort included 4.4% of pts with kidney cancer, 7.3% with colorectal cancer, 26.5% with haematological malignancies (HM), and 61.8% with breast cancer. The risk estimated by SCORE was 4.56 ±5.07%. Breast cancer pts had lower cardiovascular risk than those with HM (p = 0.001) and kidney cancer (p = 0.002). Additionally, the HM group had much higher levels of natriuretic peptides (p < 0.001) and creatinine (p = 0.008) than pts with breast cancer. The comparison with the NATPOL population data showed that our pts were more often smokers, hypertensives, and diabetics, but less frequently presented with hypercholesterolaemia. CONCLUSIONS: Patients with new diagnosis of cancer, who are candidates for potentially cardiotoxic medical treatment, have increased prevalence of significant cardiovascular risk factors and therefore should be followed by a multidisciplinary team during the therapeutic process.

The prognostic impact of neutrophil-to-lymphocyte ratio, lymphocyte-to-monocyte ratio, and platelet-to-lymphocyte ratio in patients with advanced colorectal cancer treated with first-line chemotherapy.

INTRODUCTION: Colorectal cancer is the second most frequently diagnosed malignancy and one of the leading causes of cancer-related death in Poland. Many reports of different types of cancer have indicated that blood count parameters may serve as a source of prognostic or predictive information. AIM: To assess the association between these parameters and clinical outcome in patients with advanced colorectal cancer. MATERIAL AND METHODS: We retrospectively analysed a database of 295 patients with advanced colorectal cancer treated with first-line palliative chemotherapy at our institution from January 2008 to December 2012. Blood-based parameters were measured before the first cycle of treatment. RESULTS: The median progression-free survival (PFS) was 6.7 months, and the median overall survival was 17.6 months. A high neutrophil-to-lymphocyte ratio (NLR) and a high platelet-to-lymphocyte ratio (PLR) were associated with a shorter survival (hazard ratio (HR): 1.88, p < 0.0001 for the NLR and HR: 1.39, p = 0.0054 for the PLR), but for the PLR, we observed only a not significant trend toward a worse PFS (HR = 1.25, p = 0.07 for the PLR and HR = 1.55, p = 0.0004 for the NLR). A high lymphocyte-to-monocyte ratio (LMR) was associated with a better prognosis (HR = 0.58, p ≤ 0.0001) and a longer PFS (HR = 0.73, p = 0.011). CONCLUSIONS: The blood-based parameters are readily available, reliable, and low-cost biomarkers, which can be easily incorporated into routine practice to predict the prognosis in patients with advanced colorectal cancer.

Secondary cancer in a survivor of Hodgkin's lymphoma: A case report and review of the literature.

Hodgkin's lymphoma (HL) is one of the most curable malignant diseases in adults. However, HL patients have a higher risk of developing second malignancies compared with the general population. The population of adult cancer survivors is growing, thus, the long-term effects of cancer treatment, including secondary cancer development, have become an increasingly important concern in the field of oncology. The current study presents the case of a female HL survivor who developed two secondary malignancies within 29 years of follow-up. Furthermore, a review of the literature was conducted, which focused on secondary breast and gastrointestinal cancers in HL survivors.
