Pierwotny rak płaskonabłonkowy tarczycy — opis przypadku skutecznego leczenia z 5-letnią obserwacją

Squamous cell carcinoma is an extremely rare neoplasm of the thyroid (SCTC) that represents no more than 1% of all primary thyroid malignancies. We report a case of a 42-year-old woman with rapidly growing mass in the right lower neck, primarily diagnosed in fineneedle aspiration cytology as a low-differentiated carcinoma. After the surgery, exclusion of all the other possible primary tumour locations, and immunohistochemistry tests, the diagnosis of primary squamous cell carcinoma of the thyroid gland was established. Because of close surgical margins and metastatic neck node, the patient was referred to adjuvant postoperative irradiation. With five-year follow-up the patient is free of disease and still in very good condition.Rak płaskonabłonkowy tarczycy jest bardzo rzadkim nowotworem złośliwym tarczycy, dotyczącym poniżej 1% rozpoznanych przypadków raka tego gruczołu. W niniejszej pracy przedstawiono przypadek 42-letniej kobiety z wywiadem pod postacią szybko rosnącego guza prawego płata tarczycy, pierwotnie zdiagnozowanego w biopsji cienkoigłowej jako niskozróżnicowany rak tarczycy. Po zabiegu operacyjnym, wykluczeniu innych możliwych ognisk raka i badaniu immunohistochemicznym postawiono rozpoznanie pierwotnego, płaskonabłonkowego raka tarczycy. Uwzględniając obecność wąskich marginesów chirurgicznych i przerzutu do węzła chłonnego szyjnego, chorą zakwalifikowano do pooperacyjnej radioterapii. Po zakończonym leczeniu, od 5 lat pacjentka pozostaje w obserwacji onkologicznej bez cech nawrotu choroby i w bardzo dobrym stanie sprawności

Usefulness of osteopontin (OPN) determinations in ovarian cancer patients who underwent first-line chemotherapy

Abstract Introduction: Currently CA 125 is a marker of choice for monitoring ovarian cancer. Nonetheless, scientists are still searching for new markers, which could provide additional information for the evaluation of treatment, especially in patients with normal CA 125 levels, despite the progression of the disease. According to the latest reports, OPN can be a potential new marker. Aim: Estimation of usefulness of OPN determinations in the monitoring of ovarian cancer patients. Material and Methods: The study included 54 ovarian cancer patients, undergoing chemotherapy. Markers were measured before, during and after treatment. The dynamics of the change of OPN levels was shown on line graphs, using Microsoft Excel programme. Statistical analysis was performed by Kaplan-Meier method and log-rank test. Results: 44% of patients from the study group were found to have low CA 125 levels. In these cases only the increase of OPN concentration indicated recurrence of the disease. In 43% of patients the high initial CA 125 and OPN levels decreased during chemotherapy and complete regression was stated in these patients. Nevertheless, in 13/17 patients a repeated increase of OPN concentration signalling the recurrence, earlier than CA 125 and clinical recurrence manifestation, was observed. In 13% of patients high initial levels of markers did not decrease during chemotherapy, which correlated with the progression of the disease. Our study showed that only the CA 125 levels had a significant influence (p=0.00063) on the disease-free survival time. Conclusions: Our data suggest a potential usefulness of the OPN determinations in estimating ovarian cancer recurrence. Nonetheless, there was no correlation between the initial OPN concentration and the disease-free survival time

Comparison of Selected Immune and Hematological Parameters and Their Impact on Survival in Patients with HPV-Related and HPV-Unrelated Oropharyngeal Cancer

Several immune and hematological parameters are associated with survival in patients with oropharyngeal cancer (OPC). The aim of the study was to analyze selected immune and hematological parameters of patients with HPV-related (HPV+) and HPV-unrelated (HPV−) OPC, before and after radiotherapy/chemoradiotherapy (RT/CRT) and to assess the impact of these parameters on survival. One hundred twenty seven patients with HPV+ and HPV− OPC, treated with RT alone or concurrent chemoradiotherapy (CRT), were included. Patients were divided according to HPV status. Confirmation of HPV etiology was obtained from FFPE (Formalin-Fixed, Paraffin-Embedded) tissue samples and/or extracellular circulating HPV DNA was determined. The pre-treatment and post-treatment laboratory blood parameters were compared in both groups. The neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), monocyte/lymphocyte ratio (MLR), and systemic immune inflammation (SII) index were calculated. The impact of these parameters on overall (OS) and disease-free (DFS) survival was analyzed. In HPV+ patients, a high pre-treatment white blood cells (WBC) count (>8.33 /mm3), NLR (>2.13), SII (>448.60) significantly correlated with reduced OS, whereas high NLR (>2.29), SII (>462.58) significantly correlated with reduced DFS. A higher pre-treatment NLR and SII were significant poor prognostic factors for both OS and DFS in the HPV+ group. These associations were not apparent in HPV− patients. There are different pre-treatment and post-treatment immune and hematological prognostic factors for OS and DFS in HPV+ and HPV− patients. The immune ratios could be considered valuable biomarkers for risk stratification and differentiation for HPV− and HPV+ OPC patients

Analysis of Selected Nutritional Parameters in Patients with HPV-Related and Non-HPV-Related Oropharyngeal Cancer before and after Radiotherapy Alone or Combined with Chemotherapy

Background: Radiotherapy plays an essential role in the treatment of oropharyngeal carcinoma (OPC). The aim of this study was to assess and compare the nutritional status (NS) of patients with HPV-related (HPV+) and non-HPV-related (HPV-) OPC before and after radiotherapy (RT) or chemoradiotherapy (CRT). Methods: The analysis included 127 patients with OPC who underwent radiotherapy (RT) alone, or in combination with chemotherapy (CRT), in the I Radiation and Clinical Oncology Department of Maria Skłodowska-Curie National Research Institute of Oncology, Gliwice Branch, Poland. Patients were divided according to HPV status. Confirmation of HPV etiology was obtained from FFPE (formalin-fixed, paraffin-embedded) tissue material and/or extracellular circulating HPV DNA. Basic anthropometric and biochemical parameters before and after RT/CRT were compared between the HPV- and HPV+ groups. The effect of NS on survival was also analyzed. Results: In both groups, a significant decrease in all analyzed nutritional parameters was noted after RT/CRT (p < 0.01). CRT caused significant weight loss and decreases in BMI, albumin, total lymphocyte count (TLC), and hemoglobin concentration, as well as an increase in the Nutritional Risk Score (NRS) 2002, in HPV- and HPV+ patients. A significant decrease in prealbumin levels after CRT was noted only in HPV+ patients. RT caused a significant decrease in hemoglobin concentration and TLC in HPV- patients. There were no significant differences regarding other nutritional parameters after RT in either group. RT did not have negative impact on body mass index (BMI), weight, NRS, CRP, Alb, Prealb, or PNI. Overall survival (OS) and disease-free survival (DFS) were significantly better in patients with a higher BMI in the HPV- group (OS, p = 0.011; DFS, p = 0.028); DFS was significantly better in patients with C-reactive protein (CRP) < 3.5 g/dL in the HPV- (p = 0.021) and HPV+ (p = 0.018) groups, and with total lymphocyte count (TLC) >1.28/mm3 in the HPV+ group (p = 0.014). Higher NRS 2002 was an independent adverse prognostic factor for OS and DFS in HPV-, but not in the HPV+ group. Kaplan–Meier analysis showed that both OS and DFS were significantly better in HPV- patients with lower NRS 2002 scores. However, this relationship was not observed in the HPV+ group. Conclusions: Regardless of HPV status, patients with OPC can develop malnutrition during RT/CRT. Therefore, nutritional support during RT/CRT is required in patients with HPV- and HPV+ OPC

Determinants of the level of circulating-tumor HPV16 DNA in patients with HPV-associated oropharyngeal cancer at the time of diagnosis

Abstract Circulating tumor HPV DNA (ctHPV16) assessed in liquid biopsy may be used as a marker of cancer in patients with HPV-associated oropharyngeal cancer (HPV + OPC). Factors influencing the initial ctHPV16 quantity are not well recognized. In this study we aimed to establish what factors are related to the level of ctHPV16 at the time of diagnosis. 51 patients (37 men and 14 women, median age of 57 years old) with HPV + OPC prior to definitive treatment were included. ctHPV16 was measured by qPCR. Tumor and nodal staging were assessed according to AJCC8. Blood derived factors included squamous cell carcinoma antigen (SCC-Ag), serum soluble fragment of cytokeratin 19 (CYFRA 21-1), C-reactive protein (CRP), albumin level (Alb), neutrophils (Neut), thrombocytes (Plt) and lymphocyte (Lym) count, Neut/Lym ratio were assessed. The volumes of the primary tumor (TV) and involved lymph nodes (NV) were calculated using MRI, CT or PET-CT scans. Data were analysed using parametric and nonparametric methods. Variables for multivariable linear regression analysis were chosen based on the results from univariable analysis (correlation, univariable regression and difference). There were 9 (18%), 10 (19%) and 32 (63%) patients who had TV and NV assessed in MRI, CT or PET respectively. Primary tumor neither as T-stage nor TV was related to ctHPV16 level. Significant differences in the ctHPV16 between patients with high vs low pain (P = 0.038), NV (P = 0.023), TV + NV (P = 0.018), CYFRA 21-1 (P = 0.002), CRP (P = 0.019), and N1 vs N3 (P = 0.044) were observed. ctHPV16 was significantly associated with CYFRA 21-1 (P = 0.017), N stage (P = 0.005), NV (P = 0.009), TV + NV (P = 0.002), CRP (P = 0.019), and pain (P = 0.038). In univariable linear regression analysis the same variables predicted ctHPV16 level. In multivariable analyses, CYFRA 21-1 and CRP (both as categorical variables) were predictors of ctHPV16 level even above NV. ctHPV16 at presentation is driven by tumor volume measured mostly by N. CYFRA 21-1 and CRP are additional factors related to ctHPV16 prior to the treatment
