Expression of selected molecular factors in two types of endometrial cancer
2021
BACKGROUND Endometrial cancers (EC) are a heterogeneous group of malignant neoplasms differing in etiology, clinical-pathological features and prognosis. OBJECTIVES To determine the differences between the expression of selected molecular factors and find connections between them in order to isolate possible biomarkers influencing treatment options. MATERIAL AND METHODS The investigated data involved archival histological preparations obtained from uterine EC samples taken from 137 patients, treated surgically between 2007 and 2014. The immunohistochemical Dako EnVisionTM Flex+ method was applied. RESULTS The expression of ERβ, MLH1 and BRCA1 was lower in ECI than in ECII patients. The ERα …
Characterization of Human γδ T Lymphocytes Infiltrating Primary Malignant Melanomas
2012
T lymphocytes are often induced naturally in melanoma patients and infiltrate tumors. Given that gamma delta T cells mediate antigen-specific killing of tumor cells, we studied the representation and the in vitro cytokine production and cytotoxic activity of tumor infiltrating gamma delta T cells from 74 patients with primary melanoma. We found that gamma delta T cells represent the major lymphocyte population infiltrating melanoma, and both V delta 1(+) and V delta 2(+) cells are involved. The majority of melanoma-infiltrating gamma delta cells showed effector memory and terminally-differentiated phenotypes and, accordingly, polyclonal gamma delta T cell lines obtained from tumor-infiltrat…
Skewed Differentiation of Circulating Vγ9Vδ2 T Lymphocytes in Melanoma and Impact on Clinical Outcome
2016
OBJECTIVE:The aim of this study was to evaluate over time circulating γδ T lymphocytes in melanoma patients in terms of frequency, effector functions, and relationship with clinical stage and evolution, by comparing preoperative values to those obtained at a mean follow-up of 36 months or in the event of recurrence or disease progression, and to those of healthy controls. Also, we correlated the presence of tumor-infiltrating γδ T lymphocytes with clinical evolution of melanoma. RESULTS:Mean frequencies of circulating γδ T cells before and after melanoma removal were very similar and comparable to healthy subjects, but patients who progressed to stage III or IV showed a significantly decrea…
Willingness to pay for a cure of low-risk melanoma patients in Germany
2018
Malignant melanoma is potentially life-threatening but in most cases curable if detected early. Willingness to pay (WTP) is a preference-based construct that reflects burden of disease by assessment of the monetary value for a hypothetical cure from disease. Since WTP (directly as total amount of money) has not been assessed so far in patients with low risk melanoma, it was interesting to gain insights in this patient population and then, in a second step, compare it directly with the WTP of their treating dermato-oncologists. WTP was assessed in 125 patients with low-risk melanoma and additionally in 105 treating physicians, asking for the one-time and continuous payments they would be wil…
Investigating the possible impact of peritoneal tumor exposure amongst women with early stage cervical cancer treated with minimally invasive approac…
2021
Abstract Introduction Recent findings show a detrimental impact of the minimally invasive approach on patients with early stage cervical cancer (ECC). Reasons beyond these results are unclear. The aim of the present article is to investigate the possible role of peritoneal contamination during intracorporeal colpotomy. Methods patients with early stage cervical cancer were divided into 2 groups: no intraperitoneal exposure (N-IPE) intraperitoneal exposure (IPE) during minimally invasive surgery. Patients of the 2 groups were propensity-matched according to the major risk factors. Results 226 cases of the IPE group had a significant worst prognosis than the 142 cases of the N-IPE group (4.5-…

Reliability of the pre-operative imaging to assess neck nodal involvement in oral cancer patients, a single-center study
2022
Background: Primary sites for the metastasis of oral cancer are the cervical lymph nodes. Although there has been considerable technical advancement in the radiological imaging, capability to recognize all metastatic lymph nodes pre-operatively has remained as a challenge. Thus elective neck dissection (END) has remained as reli-able practice to treat cervical lymph nodes. This study evaluated the accuracy of pre-operative imaging in pre-operative diagnostics of cervical lymph node status using computed tomography or magnetic resonance imaging in patients with oral squamous cell carcinoma (OSCC). We have also considered the reasons for the difficulties to recognise metastatic nodes in cervi…
Prognostic factors of overall survival for patients with FIGO stage IIIc or IVa ovarian cancer treated with neo-adjuvant chemotherapy followed by int…
2020
International audience; Introduction The aim of this study was to identify prognostic factors of overall survival in patients with FIGO stage IIIc or IVa ovarian cancer (OC) treated by neo-adjuvant chemotherapy (NAC) followed by interval debulking surgery.Materials and methods Data from 483 patients with ovarian cancer were retrospectively collected, from January 1, 2000 to December 31, 2016, from the FRANCOGYN database, regrouping data from 11 centers specialized in ovarian cancer treatment. Median overall survival was determined using the Kaplan-Meier method. Univariate and multivariate analysis were performed to define prognostic factors of overall survival.Results The median overall sur…
Small renal tumors: correlation of clinical and pathological features with tumor size.
2007
We analyzed the association between tumor diameter and pathological stage, histological subtype, tumor grade and the incidence of metastases in renal cell carcinoma with a diameter of up to 4 cm (clinical stage T1a).We analyzed a consecutive series of 663 patients with renal tumors 4 cm or less who underwent surgery at our institution between 1990 and 2006. After excluding 115 patients (17.3%) with benign tumors 548 with renal cell carcinoma were included in the study. Tumor size on preoperative imaging was correlated with pathological stage, tumor grade, histological subtype and incidence of metastases at diagnosis. For data analysis tumors were stratified by tumor diameter into 3 groups, …
Multiplicity and history have a detrimental effect on survival in patients with T1G3 bladder tumors selected for conservative treatment.
2008
Purpose: In the absence of Tis tumor we assessed whether history and multiplicity have a detrimental effect on conservative treatment in carefully selected patients with T1G3 bladder carcinoma. Materials and Methods: Between January 1976 and December 1999, 165 select patients with T1G3 bladder tumors were conservatively treated with transurethral resection plus adjuvant intravesical therapy. Patients with concomitant or previous Tis, previous T1G3, tumor size greater than 3 cm and more than 3 lesions were excluded from analysis. Repeat transurethral resection was not routinely performed. However, cytology had to be negative for atypia before the start of adjuvant intravesical therapy. Resul…
