Background: Rectal cancer constitutes nearly one-third of all colorectal cancer diagnoses, and certain clinical and molecular markers have been studied as potential prognosticators of patient survival. The main objective of our study was to investigate the relationship between the expression intensities of certain proteins, including growth-hormone-releasing hormone receptor (GHRH-R), Hsp90, Hsp16.2, p-Akt and SOUL, in specimens of locally advanced rectal cancer patients, as well as the time to metastasis and 10-year overall survival (OS) rates. We also investigated whether these outcome measures were associated with the presence of other clinical parameters. Methods: In total, 109 patients were investigated retrospectively. Samples of pretreatment tumors were stained for the proteins GHRH-R, Hsp90, Hsp16.2, p-Akt and SOUL using immunhistochemistry methods. Kaplan–Meier curves were used to show the relationships between the intensity of expression of biomarkers, clinical parameters, the time to metastasis and the 10-year OS rate. Results: High levels of p-Akt, GHRH-R and Hsp90 were associated with a significantly decreased 10-year OS rate (p = 0.001, p = 0.000, p = 0.004, respectively) and high expression levels of p-Akt and GHRH-R were correlated with a significantly shorter time to metastasis. Tumors localized in the lower third of the rectum were linked to both a significantly longer time to metastasis and an improved 10-year OS rate. Conclusions: Hsp 90, pAkt and GHRH-R as well as the lower-third localization of the tumor were predictive of the 10-year OS rate in locally advanced rectal cancer patients. The GHRH-R and Hsp90 expression levels were independent prognosticators of OS. Our results imply that GHRH-R could play a particularly important role both as a molecular biomarker and as a target for the anticancer treatment of advanced rectal cancer.

Összefoglaló.Bevezetés: Az európai országok közül Magyarország a colorectalis daganatos incidencia és mortalitás szempontjából az élen szerepel. Ennek hátterében a beteghez vagy az egészségügyi rendszerhez köthető tényezők is állhatnak. Célkitűzés: Kutatásunk célja, hogy pilotvizsgálat keretében feltárjuk a colorectalis daganatos betegek kezeléshez jutásának körülményeit azáltal, hogy a betegek első tünetei, kivizsgálásuk jellemzői, betegségük stádiuma és a terápiáig eltelt időtartamok közötti összefüggéseket elemezzük. Módszer: Retrospektív adatgyűjtés történt 26, Baranya megyei háziorvosi praxis colorectalis daganatos betegeinek (n = 212) adataira vonatkozóan a praxisok, valamint a Pécsi Tudományegyetem Klinikai Központjának (PTE KK) adatbázisából. Meghatároztuk a terápiáig eltelt intervallumot (TEI), amely az első orvos-beteg találkozástól - amikor a beteg colorectalis daganatra utaló tünetekkel először jelentkezett orvosnál - a terápia megkezdésének első napjáig eltelt időt jelenti. A statisztikai elemzés során deskriptív analízist, valamint varianciaanalízist végeztünk. Eredmények: A sürgősségire került betegek leggyakoribb tünete a hasi/végbéltáji fájdalom volt, míg a háziorvost felkereső betegek a véres székletet említették a legtöbbször. A sürgősségi osztályon jelentkező betegek esetében lényegesen magasabb arányban (61%) diagnosztizáltak késői (III-IV.) stádiumú daganatot, mint a háziorvoshoz forduló betegek körében (42,7%). A TEI rövidebb volt, ha a betegek sürgősségi osztályra kerültek (TEI-medián: 15 nap késői, 34,5 nap korai [I-II.] stádiumú daganat esetén), mint amikor háziorvosnál jelentkeztek először (TEI-medián: 86 nap késői, 83 nap korai stádiumú daganat esetén). Következtetés: A sürgősségi és a háziorvosi kivizsgálás esetén észlelt TEI-k összemérhetők a nyugat-európai országokéival. A hazai magas mortalitási mutatók hátterében inkább a betegek késedelmes orvoshoz fordulása állhat, ami a primer és szekunder prevenció fontosságára hívja fel a figyelmet.

Patient-related and healthcare-related factors may all play a role.OBJECTIVE:Our objective was to investigate the characteristics related to the treatment of colorectal cancer patients by analysing their initial symptoms, disease stage, referral characteristics and total treatment intervals.METHOD:A retrospective study was conducted based on data from colorectal patients (n = 212) from the databases of 26 general physician practices and the University of Pécs, Clinical Center. The total treatment interval was determined as the number of days from the first patient-physician consultation with symptoms until the first day of treatment. Descriptive analysis and analysis of variance were performed.RESULTS:Patients' most common symptom was abdominal/rectal pain when presenting at the emergency department while bloody stool was the most common among patients visiting their general physicians. The proportion of patients with advanced stage (III-IV) cancer was significantly higher at the emergency department than among patients visiting their general physicians (61% and 42.7%, respectively). The total treatment interval was shorter when patients presented at the emergency department (total treatment interval median: 15 days for advanced stage, 34.5 days for early [I-II] stage cancer) than when they initially visited their general physicians (total treatment interval median: 83 days for early stage, 86 days for advanced stage cancers).CONCLUSION:The total treatment intervals for patients visiting the emergency department or their general physicians were similar to those found in Western European countries. The high mortality rates in Hungary are more probably due to patient-related delays, which highlight the importance of primary and secondary prevention. Orv Hetil. 2021; 162(4): 153-160.

Background Previous studies have shown that patients who underwent renal transplantation were at a greater risk of developing malignancies. Due to advances in effective surgical techniques and immunosuppressive therapies, organ recipients live longer. Yet, there is insufficient information about the recommended type of therapy for colorectal cancer patients following transplantation. We describe the oncological treatment of a patient with renal transplantation, who presented with metastatic colon cancer 5 years after transplantation. Case presentation A 66-year-old Caucasian male patient, with hypertension, type 2 diabetes mellitus, paroxysmal atrial fibrillation, and renal failure underwent successful kidney transplantation in 2013. In April 2018, the adenocarcinoma of the sigmoid colon was found, and surgical resection was performed. The histological diagnosis was low-grade adenocarcinoma. Fluorodeoxyglucose positron emission tomography/computerized tomography scan showed a 2.5-cm metastasis in the VIIth segment of the liver and a metastatic paraaortical lymph node on the left. The clinical diagnosis was, therefore, metastatic (stage IV) sigmoid colon cancer (AJCC TNM system). The ongoing medications of the patient included immunosuppressive drugs and medication for his cardiovascular comorbidities. In July 2018, palliative cetuximab plus folinic acid–fluorouracil–irinotecan chemotherapeutic treatment was initiated, then cetuximab was substituted for panitumumab because of adverse events. In August 2018, the follow-up positron emission tomography/computerized tomography scan revealed stable disease. Because of side effects, the patient was unwilling to continue with the panitumumab plus folinic acid–fluorouracil–irinotecan treatment regimen. Therefore, the patient received 10× 5 Gy stereotactic body irradiation for his liver metastasis and mono-panitumumab therapy. By January 2019, the positron emission tomography/computerized tomography scan showed regression of the liver metastasis but a progression in the paraaortic lymph node. Therefore, 5× 8 Gy stereotactic irradiation was given to the paraaortic lesion. Meanwhile, the patient received altogether 16 cycles of panitumumab until June 2019, when complete remission was attained. In July 2019, the patient suffered a hemorrhagic stroke, probably due to his cardiovascular comorbidities, and died subsequently. Conclusions Since information is scarce regarding oncological treatment of patients following organ transplantation, data about their oncological treatment is essential. To our knowledge, this is the first case report to describe the successful chemotherapy and targeted therapy supplemented with stereotactic radiotherapy of a posttransplant patient with metastatic colorectal cancer.

Background: Mortality from colorectal cancer (CRC) in Hungary is the highest in Europe. It was the aim of the present study to determine the wait times from first presentation to diagnosis, in a sample of Hungarian patients with CRC, as well as to assess the stages of CRC at diagnosis. Methods: A retrospective study based on data from 212 patients with CRC in Baranya county was carried out. Data extraction was performed from 26 GP practices and from the database of the University of Pecs Clinical Center. Total Diagnostic Interval (TDI) was determined as the number of days from the first patient-physician consultation with symptoms until the pathologically confirmed date of diagnosis. Total Treatment Interval (TTI) was calculated until the first day of any form of treatment. Statistical analyses, descriptive analysis and analysis of variance, were performed. Results: A minority (36.8%) of the diagnosed CRC cases were early stage cancers (Stages I-II), while the majority (59.9%) of the cases were diagnosed as advanced stage (Stages III-IV) cancers. The median TDI was 41 days, and the median TTI was 67 days. There was a wide range between minimum and maximum waiting times regarding both diagnosis and initiation of therapy (369-371 days). Conclusions: Wait times to diagnosis and treatment of CRC in Hungary are similar to Western countries however the ratio of advanced cancers at diagnosis is higher. The cause of late diagnosis may be due to patient delay, indicating the need for implementation of primary and secondary prevention.
