The Real-Life Impact of Primary Tumor Resection of Synchronous Metastatic Colorectal Cancer-From a Clinical Oncologic Point of View.

AIM: The complex medical care of synchronous metastatic colorectal (smCRC) patients requires prudent multidisciplinary planning and treatments due to various challenges caused by the primary tumor and its metastases. The role of primary tumor resection (PTR) is currently uncertain; strong arguments exist for and against it. We aimed to define its effect and find its best place in our therapeutic methodology. METHOD: We performed retrospective data analysis to investigate the clinical course of 449 smCRC patients, considering treatment modalities and the location of the primary tumor and comparing the clinical results of the patients with or without PTR between 1 January 2013 and 31 December 2018 at the Institute of Oncotherapy of the University of Pécs. RESULTS: A total of 63.5% of the 449 smCRC patients had PTR. Comparing their data to those whose primary tumor remained intact (IPT), we observed significant differences in median progression-free survival with first-line chemotherapy (mPFS1) (301 vs. 259 days; p < 0.0001; 1 y PFS 39.2% vs. 26.6%; OR 0.56 (95% CI 0.36-0.87)) and median overall survival (mOS) (760 vs. 495 days; p < 0.0001; 2 y OS 52.4 vs. 26.9%; OR 0.33 (95% CI 0.33-0.53)), respectively. However, in the PTR group, the average ECOG performance status was significantly better (0.98 vs. 1.1; p = 0.0456), and the use of molecularly targeted agents (MTA) (45.3 vs. 28.7%; p = 0.0005) and rate of metastasis ablation (MA) (21.8 vs. 1.2%; p < 0.0001) were also higher, which might explain the difference partially. Excluding the patients receiving MTA and MA from the comparison, the effect of PTR remained evident, as the mOS differences in the reduced PTR subgroup compared to the reduced IPT subgroup were still strongly significant (675 vs. 459 days; p = 0.0009; 2 y OS 45.9 vs. 24.1%; OR 0.37 (95% CI 0.18-0.79). Further subgroup analysis revealed that the site of the primary tumor also had a major impact on the outcome considering only the IPT patients; shorter mOS was observed in the extrapelvic IPT subgroup in contrast with the intrapelvic IPT group (422 vs. 584 days; p = 0.0026; 2 y OS 18.2 vs. 35.9%; OR 0.39 (95% CI 0.18-0.89)). Finally, as a remarkable finding, it should be emphasized that there were no differences in OS between the smCRC PTR subgroup and metachronous mCRC patients (mOS 760 vs. 710 days, p = 0.7504, 2 y OS OR 0.85 (95% CI 0.58-1.26)). CONCLUSIONS: The role of PTR in smCRC is still not professionally justified. Our survey found that most patients had benefited from PTR. Nevertheless, further prospective trials are needed to clarify the optimal treatment sequence of smCRC patients and understand this cancer disease's inherent biology.

[Systemic treatment of adult gliomas: a narrative review]. / A felnottkori gliómák gyógyszeres kezelése.

Gliomas are considered as locally aggressive diseases, consequently, surgery and radiotherapy are the basic therapies of the glial tumors. Nevertheless, the long-term ineffectiveness of the local treatment modalities and the frequently observed relapses explain the unmet medical need for the elaboration of effective systemic treatment regimes. In the last few decades of the 20th century, the use of different chemotherapeutic agents and their combinations, and the alternative administration of drugs have been in the therapeutic forefront of gliomas, whereas, later, in the first years of this century temozolomide was introduced to the everyday clinical practice as the most effective "anti-glioma" medicine, and it is still widely used both in monotherapy and in different combinations. Nevertheless, in the last two decades, considering the recognition of different predictive molecular markers, different targeted therapies, e.g. VEGFR inhibitor agents were also introduced into the routine clinical practice, and there have been promising results published in immunotherapy trials in the recent years, as well. Besides the promising results with the novel systemic therapies, it should be emphasized that both in the primary and the salvage care of the glial tumors the most effective treatment options are the individualized combinations of local and systemic treatment modalities, with the proper interpretation of brain imaging data and patient-centered clinical management.

The Real-Life Impact of mFOLFIRI-Based Chemotherapies on Elderly Patients-Should We Let It or Leave It?

AIM: The oncologic treatment of elderly patients is going on with a lack of evidence due to their underrepresentation in clinical trials. Many data suggest that certain groups of elderly patients, like their younger counterparts, may benefit from the systemic treatment of their metastatic colorectal tumors (mCRC). METHOD: We performed retrospective data analysis to investigate the clinical course of care and clinical outcomes of 515 patients who received first-line mFOLFIRI-based chemotherapy for mCRC between 1 January 2013 and 31 December 2018 at the Institute of Oncotherapy of the University of Pécs, focusing on a comparison of patients over and under 70 years of age, defined as the cut-off value. RESULTS: 28.7% of the 515 patients were 70 years old and older (median age 73.5 years). Compared to the data of the elderly patients, the younger group (median age 61.1 years) had a performance status that was significantly better (average ECOG 1.07 vs. 0.83, p < 0.0001), and significantly more patients received molecularly targeted agents (MTA) (21.6% vs. 51.8%, p < 0.0001); nevertheless, mPFS (241 vs. 285 days, p = 0.3960) and mOS (610 vs. 698 days, p = 0.6305) results did not differ significantly. Considering the 1y PFS OR and the 2ys OS OR values (0.94 [95%CI 0.63-1.41] and 0.72 [95%CI 0.47-1.09], respectively), only a non-significant trend was observed in OS favouring the younger population. Additional analysis of our data proved that the survival in patients over 70 years was positively affected by the addition of MTAs to the doublet chemotherapies, and the reasonable modifications/reductions in dose intensity and the addition of local interventions had similar positive effects as observed in the younger patients' group. CONCLUSIONS: Age stratification of mCRC patients is not professionally justified. Patients over 70 years of age with good performance status and controlled co-morbidities benefit from systemic therapy, its modifications and local treatment to the same extent as younger patients. With the increasing incidence of age-related cancers due to the rising average lifespan, prospective randomised clinical trials are needed to determine the real value of systemic therapy in the elderly and the rational, objective methods of patient selection.

[Pancreatic cancer with liver metastases: is it possible to improve survival by resection of oligopersistent primary tumor following neoadjuvant chemotherapy?] / Májáttétes pancreasrák: meghosszabbítható-e a túlélés az oligoperzisztens primer daganat neoadjuváns kemoterápiát követo reszekciójával?

The prognosis of pancreatic cancer is one of the worst of all cancers. Though the routine use of modern targeted and immunotherapy is still pending, the recently applied new chemotherapy combinations resulted in obvious improvement in the clinical management of pancreatic cancer. Adjuvant treatment followed by radical operation can increase the survival of the patients, moreover, neoadjuvant therapy for locally advanced tumors is associated with higher resectability rate. However, in metastatic disease only palliative chemotherapy could be indicated due to the dismal prognosis. The introduction of new chemotherapy combinations produced a major evolution by extending the median survival time of these patients. According to recent publications, even complete remission of the metastases can be achieved by the palliative chemotherapy, justifying a radical operation. This approach can be more advantageous, compared to patients treated with chemotherapy only. Reporting our two primary metastatic cases, we also endorse this new approach. The clinical significance of complex management is justified in the case of oligopersistence which is traditionally treated only with palliative systemic therapy.

[Radiotherapy of kidney cancers: an allegory for changing approach in theory and practice]. / A vesedaganatok sugárkezelése: a megváltozott sugárterápiás szemlélet és klinikai gyakorlat példázata.

The evolution of radiotherapy (RT) technologies in the last two decades has changed the RT treatment attitude, and the routine application of novel stereotactic methods has opened new avenues in the complex cancer care. To prove the clinical consequences of this paradigm shift, a good example is the transformation of the renal cell carcinoma (RCC) treatment strategy. RCC was originally considered as a radioresistant disease, however, the introduction of new RT technologies has provided a risk-free focal dose escalation, so RT in primary or metastatic RCCs has become a more efficient method. Meanwhile, there has also been a spectacular development in the medical treatment of advanced RCC, thus the treatment strategy has radically changed in this field of oncology, resulting in a remarkably increased effectiveness. In the present communication, we summarize the steps of recent RT evolution, the new fields of indications and possibilities of combination therapies in RCC.

[Multicentric Hungarian results of cabozantinib therapy in patients with metastatic kidney cancer based on real-world data]. / Áttétes vesedaganatos betegek kabozantinibterápiájának multicentrikus magyarországi eredményei.

The aim of our analysis was to evaluate the efficacy of cabozantinib in patients with metastatic renal cell carcinoma. Cabozantinib therapy initiated between 01/01/2019 and 31/12/2022 was evaluated based on a retrospective review of data from 14 renal centers in Hungary. The starting dose was 60 or 40 mg. Physical examinations and laboratory tests were performed every 4 weeks and imaging studies 3-monthly. Tumor response was assessed according to RECIST 1.1, and toxicity according to NCI CTCAE 4.0. A total of 230 patient records were evaluated, 201 (87.4%) of them had clear cell RCC. Cabozantinib was administered as third, second and first-line treatment in 48.7%, 38.3% and <5% of cases, respectively. Dose reductions occurred in 62.6% and treatment interruption in 6.5%. Duration of therapy was 10.03 months, which was independent of dose reduction. Overall tumor response rate was 39.2% and clinical benefit was 82.8%. The duration of first-, second-, third- and fourth-line treatment was 11.47, 8.03, 11.57 and 10.13 months, respectively. Overall survival from the start of therapy was 22.0 months. Cabozantinib therapy in daily practice was more beneficial than according to registry study results. Dose reduction did not affect efficacy.

Real-Life Effectivity of Dose Intensity Reduction of First-Line mFOLFIRI-Based Treatment of Metastatic Colorectal Cancers: Sometimes Less Is More.

Aim: The key purposes of the treatment of metastatic malignancies are to extend survival and maintain the quality of life. Recently it has been emphasized in the scientific literature that the maintenance of maximal dose intensity is not always beneficial. Method: We examined the effectiveness of first-line mFOLFIRI-based treatments used in mCRC indication in 515 patients, treated between 1 January 2013 and 31 December 2018 at the Department of Oncotherapy of the University of Pécs, on a basis of real-world retrospective data analysis. We studied the effect of decreased dose intensity treatment modifications on patient survival. Results: 45% of all patients achieved the optimal relative dose intensity (RDI) of 85%, and the median progression-free and overall survival (mPFS, mOS) were 199 and 578 days, compared to 322 and 743 days, (mPFS p < 0.0002, 1 y (year) PFS OR (odds ratio) 0.39 (95% CI: 0.26−0.56) and mOS p = 0.0781, 2 yrs OS OR 0.58 (95% CI: 0.39−0.85), respectively) in the group of patients not achieving the RDI of 85%. Conclusions: Decreased dose intensity did not reduce the effectiveness of treatment; in fact, there was a significant improvement in most of the analyzed parameters. The option of reduced dose intensity, which shows the same or even better results with less toxicity, should definitely be considered in the future palliative treatment of mCRC patients.

Factors affecting prognosis in patients treated with bevacizumab plus paclitaxel as first-line chemotherapy for HER2-negative metastatic breast cancer: an international pooled analysis of individual patient data from four prospective observational studies.

BACKGROUND: Bevacizumab (BV) plus paclitaxel (PTX) is a treatment option in patients with HER2-negative metastatic breast cancer (mBC). We conducted an international pooled analysis with individual patient data to evaluate the effectiveness of BV + PTX as a first-line treatment for HER2-negative mBC patients under routine practice. METHODS: A total of 2,474 mBC patients treated with BV + PTX from four prospective observational studies were analyzed. The primary endpoint was overall survival (OS). The other endpoints including identifying independent prognostic factors and validation of the modified Prognostic Factor Index (PFI) developed in the ATHENA trial. RESULTS: Median follow-up time was 10.9 months (M). Median OS were 21.4 M (95% confidential interval 19.8-22.7 M). The seven independent prognostic factors (tumor subtype, age, ECOG performance status (PS), disease-free interval (DFI), liver metastases, number of metastatic organs, and prior anthracycline and/or taxane treatment) for OS found in this analysis included the five risk factors (RFs [DFI < 24 months, ECOG PS 2, liver metastases and/or > 3 metastasis organ sites, TNBC, prior anthracycline and/or taxane therapy]). High- (> 3 RFs [median OS 12.6 M]) and intermediate-risk groups (2 RFs [median OS 18.0 M]) had a significantly worse prognosis than the low-risk group (< 1 RF [median OS 27.4 M]), (p < 0.0001). CONCLUSIONS: This international pooled analysis showed the effectiveness of first-line BV + PTX for HER2-negative mBC patients identifying seven independent prognostic factors as real-world evidence. The usefulness of the modified PFI developed in the ATHENA trial in predicting OS among patients receiving BV + PTX was also verified.

Literature review of evidence-based follow-up strategies of cancer patients / Daganatos betegek evidencia alapú gondozási stratégiáinak irodalmi áttekintése

An increasing proportion of cancer patients remains permanently tumorfree after primary care due to modern curative treatments. However, the life expectancy and quality of life deteriorate significantly in most relapsed cases in spite of different palliative therapies. To detect the early relapse in asymptomatic stage, patients undergo a preplanned care process, targeting primarily their improved survival. Several studies and reviews have been conducted in recent decades to determine the optimal and rational frequency and methods of control examinations. The data of different followup strategies were analyzed from several perspectives. Recommended followup protocols differ significantly based on the origin, histological characteristics, stage, prognostic factors and typical sites of recurrences, such as local, "oligometastatic" or systemic relapse of tumors. In addition to the detection of recurrence, the importance of qual ity of life, monitoring of psychological status and psychosomatic complaints as well as the costeffectiveness of protocols also came to the focus. Involving family doctors or qualified nurses in routine oncology followup may function as an alternative option to reducing the workload of specialists. The COVID­19 pandemic resulted in the use of telemedicine methods in the evaluation of examinations and followup strategies coming to the fore, while at the same time this made the reevaluation of control care algorithms even more important. In this paper, we review the results of studies comparing the different followup strategies, highlighting which protocols help to optimize the use of health care capacity while preserving the survival chance of cancer patients in relapse.

Radiotherapy of Breast Cancer-Professional Guideline 1st Central-Eastern European Professional Consensus Statement on Breast Cancer.

The international radiotherapy (RT) expert panel has revised and updated the RT guidelines that were accepted in 2020 at the 4th Hungarian Breast Cancer Consensus Conference, based on new scientific evidence. Radiotherapy after breast-conserving surgery (BCS) is indicated in ductal carcinoma in situ (stage 0), as RT decreases the risk of local recurrence (LR) by 50-60%. In early stage (stage I-II) invasive breast cancer RT remains a standard treatment following BCS. However, in elderly (≥70 years) patients with stage I, hormone receptor-positive tumour, hormonal therapy without RT can be considered. Hypofractionated whole breast irradiation (WBI) and for selected cases accelerated partial breast irradiation are validated treatment alternatives to conventional WBI administered for 5 weeks. Following mastectomy, RT significantly decreases the risk of LR and improves overall survival of patients who have 1 to 3 or ≥4 positive axillary lymph nodes. In selected cases of patients with 1 to 2 positive sentinel lymph nodes axillary dissection can be substituted with axillary RT. After neoadjuvant systemic treatment (NST) followed by BCS, WBI is mandatory, while after NST followed by mastectomy, locoregional RT should be given in cases of initial stage III-IV and ypN1 axillary status.

Treatment of patients with malignant pleural effusion in a tertiary oncology center during the COVID-19 pandemic / Malignus pleuralis effusiókkal küzdo betegek ellátása egy regionális onkológiai központban a COVID-19-pandémia idoszakában

Introduction: Malignant pleural effusion is a complication of tumors heralding poor outcome. It may be life-threat- ening, so advanced cases should be treated as an oncological emergency. Objective: We aimed to provide complex care to patients with malignant pleural effusion during the COVID-19 pandemic at the University of Pecs Medical School, in the Department of Oncotherapy. During the pandemic, we introduced the thoracocentesis as a routine method in our department without previous experiences. Method: Results of diagnosing and treating pleural effusion of patients between March 18th of 2020 and May 31st of 2021 were summarized. Results: We have analyzed data of 45 patients, two-thirds (66.7%) of them were women, the median age was 67 years. 57.8% of patients received systemic anticancer therapy during the study. The total number of thoracocentesis was over 120, one-third of the patients required more than five interventions. Only three iatrogenic pneumothorax cases were detected, no other serious complications were experienced. The procedures - that were aimed to mitigate symptoms in most cases (80%) - were considered successful. However, 48.9% of the patients were no longer alive at the end of the study period indicating very poor prognosis of pleural carcinosis. Discussion and conclusion: Clinical care of oncological patients was continuous during the pandemic; patients treated as part of emergency care were often seen in advanced disease state. Treatment of malignant pleural effusion requires oncological foresight as well as implementing an invasive approach. Our study has shown that discussion of the topic is relevant, may reveal difficulties and need for improvement. Our results are consistent with literature data, we have experienced less complications than reported in the literature.

Changes in surgical principles as a result of modern, effective, perioperative treatments / A sebészeti elvek változása a modern, hatékony, perioperatív onkológiai kezelések következményeként

Oncology has evolved to a great extent over the last quarter of century. The significant success is multifactorial, including primary and secondary prevention, the development of diagnostics, new methods of chemo-and radiotherapy, and the integration of basic research results into practice. From the point of view of surgery, the establishing and widespread practical application of the principles of preoperative oncotherapy played a major role in this development. Between 1997 and 2005, 44 patients with gastric cancer and 102 patients with borderline resectable or irresectable esophageal cancer received perioperative treatment at the Department of Surgery of the University of Pecs. The response rate was above 50% in both groups and complete pathological remission was achieved in 3 patients with gastric cancer and 17 patients with esophageal cancer. Based on our own experience and literature data, the development of seven new principles in surgical oncology were observed as the result of a very successful preoperative oncologic treatment. The desired free resection margin was reduced to the millimeter dimension in many cancer cases. Thus so-called organ-preserving procedures were made possible. Regarding the prognosis, the stage after the treatment became determinant. Complete histopathological remission could also be achievable in patients with oligometastases. In the case of a complete remission, the watch and wait tactics emerged as an option. Along the preoperative treatment of resectable colorectal liver metastases, there is no need to strive for complete remission. The treatment order of the primary tumor and its metastases can be reversed. Based on the improving results of oncology treatments, a reduction in surgical activity in the treatment of cancer patients is expected.

IMAT-IGRT Treatment with Simultaneous Integrated Boost as Dose Escalation for Patients with Cervical Cancer: A Single Institution, Prospective Pilot Study.

Purpose: The aim of this study was to introduce the simultaneous integrated boost (SIB) technique to assess the safety of replacement of the brachytherapy (BT) boost for ineligible patients with cervical cancer receiving radiochemotherapy (RCT). Methods: Fourteen patients were enrolled between 2015 and 2018. SIB was delivered using RapidArc technique at doses of 2.4 Gy per fraction during pelvic irradiation with 50.4/1.8 Gy in seven patients (to a total dose of 67.2 Gy) with limited volume disease. In 7 patients with a more advanced disease stage (>5 cm tumor, parametric invasion both sides), parametric boost therapy was added to the pelvic radiotherapy to a total dose of the macroscopic tumor of 79.2 Gy. All patients received simultaneous cisplatin-based chemotherapy for 5 cycles with a dosage of 40 mg/m2. We examined acute toxicity (CTCAE v4.1) and quality of life (EORTC QLQ30 and CX24). The tumor regression rate was evaluated with RECIST 1.1 after the first 3- to 4-months follow-up Magnetic Resonance Imaging (MRI) scan. We calculated the percentage of tumor regression rate and the local control during the follow-up period and evaluated the survival data. Results: Our patient data are presented at a median follow-up time of 24.5 months. During the treatment period, no grade 3 to 4 toxicity was observed. During the follow-up period, no late-onset toxicity was observed. The tumor regression rate at the first MRI scan was 95.31% on average. Disease free survival (DFS) during the median follow-up of 24 months was 98.6%. Conclusion: In patients with cervical cancer, the SIB technique is amenable as part of definitive RCT. Dose escalation with the SIB technique can be safely administered to cervical cancer patients during definitive RCT if BT is not feasible. However, further randomized clinical studies are needed to validate the method, so routine use of it cannot be recommended yet.

Összefoglaló. Bevezetés: Magyarországon a vastag- és a végbéldaganat mindkét nem esetében a harmadik leggyakoribb daganatos megbetegedés és a második leggyakoribb halálok. Célkituzés: Elemzésünk célja volt a vastag- és végbéldaganat okozta éves epidemiológiai és egészségbiztosítási betegségteher meghatározása Magyarországon. Adatok és módszerek: Az adatok a Nemzeti Egészségbiztosítási Alapkezelo (NEAK) finanszírozási adatbázisából származnak, és a 2018. évet fedik le. A daganat típusait a Betegségek Nemzetközi Osztályozása (BNO, 10. revízió) szerinti C18-as, C19-es, C20-as, C21-es, D010-D014-es és D12-es kóddal azonosítottuk. Meghatároztuk az éves betegszámokat korcsoportos és nemek szerinti bontásban, a prevalenciát 100 000 lakosra, az éves egészségbiztosítási kiadásokat valamennyi ellátási formára és daganattípusra vonatkozóan. Eredmények: A vastag- és végbéldaganatok kezelésére a NEAK 21,7 milliárd Ft-ot (80,2 millió USD; 68,0 millió EUR) költött 2018-ban. A költségek 58,0%-át az aktívfekvobeteg-szakellátás költségei teszik ki. Az összköltségek megoszlása szerint a legmagasabb költségek a férfiaknál (4,98 milliárd Ft) és a noknél (3,25 milliárd Ft) is a 65-74 éves korcsoportban figyelhetok meg. A legnagyobb betegszámot a járóbeteg-szakellátás esetében találtuk: 88 134 fo, ezt a háziorvosi ellátás (55 324 fo) és a CT, MRI (28 426 fo) követte. A vastagbél rosszindulatú daganata esetében az egy betegre jutó aktívfekvobeteg-kassza alapján az éves egészségbiztosítási kiadás 1,206 millió Ft (4463 USD/3782 EUR) volt a férfiak és 1,260 millió Ft (4661 USD/3950 EUR) a nok esetében. Következtetés: Hazánkban az aktívfekvobeteg-szakellátás bizonyult a fo költségtényezonek, mely magában foglalja az onkoterápiás gyógyszeres költségeket is. Orv Hetil. 2021; 162(Suppl 1): 14-21. INTRODUCTION: Colorectal cancer is the third most common type of cancer and the second most common cause of mortality in Hungary in both sexes. OBJECTIVE: The aim of our study was to determine the annual epidemiological disease burden and health insurance cost of colorectal cancer in Hungary. DATA AND METHODS: Data were derived from the financial database of the National Health Insurance Fund Administration (NHIFA) of Hungary for the year 2018. Types of cancer were identified with the following codes of the International Classification of Diseases, 10th revision: C18, C19, C20, C21, D010-D014, D12. The data analysed included annual patient numbers according to age groups and sex, prevalence of care utilisation per 100 000 population, and annual health insurance costs for all types of care and all cancer types. RESULTS: In 2018, NHIFA spent 21.7 billion HUF (80.2 million USD, 68.0 million EUR) on the treatment of colorectal cancer. 58.0% of the costs was spent on acute inpatient care. Regarding total costs, the highest costs were found in the 65-74 age group in both men (4.98 billion HUF) and women (3.25 billion HUF). The highest patient numbers were in outpatient care: 88 134 patients, general practice care (55 324 patients) and CT, MRI (28 426 patients). The annual health care treatment cost per patient was 1.206 million HUF (4463 USD/3782 EUR) in men and 1.260 million HUF (4661 USD/3950 EUR) in women. CONCLUSION: Acute inpatient care, including the costs of oncotherapeutic pharmaceuticals, was found to be the major cost driver in Hungary. Orv Hetil. 2021; 162(Suppl 1): 14-21.

Effective chemotherapy and targeted therapy supplemented with stereotactic radiotherapy of a patient with metastatic colon cancer following renal transplantation: a case report.

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.

Az onkoterápiás megbeszéléseken egyéves idoszak alatt 21 orvos, több adminisztrátor, klinikai kutatási munkatárs, szakdolgozó, gyógyszerész és pszichológus vett részt, a résztvevok szakmai tapasztalata igen széles spektrumot fedett le. A megbeszélések során az egyes betegek onkológiai életútja került részletes diszkusszióra interaktív formában, végül a döntési részletek rögzítésre kerültek a központi informatikai rendszerben. Megfigyeléseink rávilágítottak a csapatmunka elonyeire, illetve a csoport által ellátott feladatok megosztó, kiegyensúlyozó, oktatást segíto hatásaira. Az orvosok által kitöltött kérdoívek pedig bizonyították, hogy a közvetlen munkatársak közötti szakmai megbeszélés, egyféle "Bálint-csoport" muködésként a pszichés terhek megosztásában is szerepet játszhat. Következtetés: A rákgyógyítás területén az elmúlt évek során bekövetkezett gyors fejlodés, a fokozott elvárások, illetve az ezen a területen végzett, sokszor igen összetett és lelkileg is megterhelo szakmai munka kiemelten fontossá teszi a hatékony minoségbiztosítási módszerek és együttmuködési formák alkalmazását, melyek segítségével lehetoség nyílik a szakmai eszmecseréken át a többirányú tudástranszferre és a kiégést megelozo csoportventilációra. Orv Hetil. 2021; 162(9): 344-351. INTRODUCTION: The teamwork, the cooperation is always able to elevate effectiveness in every field of life. The tumor board meetings which are widely used in cancer treatment process in the last decades were originally established to warrant the medical, educational and legal quality assurance. Over these aspects, here we present the possibilities and dilemmas of the team work in the communication practices and most of all the psychological support of the participants. METHOD AND RESULTS: The two-level oncotherapy tumor board system was introduced 12 years ago at the Institute of Oncotherapy, Clinical Center, University of Pécs. During a one-year long observation period, 21 physicians and several administrators, study coordinators, pharmacists, nurses and psychologists with different experiences participated in the oncotherapy tumor board discussions. In the meetings, the specific cancer histories of the patients were analyzed in an interactive form, and finally the detailed decisions were stored in the medical database system. Our observations proved the advantages, moreover, the task sharing, balancing and educational effects of the teamwork. The results obtained from the questionnaires filled out by the physicians proved that the direct conversation between department colleagues works like a case-discussing "Bálint-group" in taking the role of distributing of the psychological burden of the physicians. CONCLUSION: The immense advancements in cancer treatment during the last years, moreover, the increased expectations and the complex and mentally charging professional tasks all demand the establishment of more effective quality control and cooperation methods. Introducing these new methods, it would lead to more efficient professional discussions, knowledge transfer and burnout preventive group-related psychological ventilation.

Is an Immunosuppressive Microenvironment a Characteristic of Both Intra- and Extraparenchymal Central Nervous Tumors?

In spite of intensive research, the survival rates of patients diagnosed with tumors of the central nervous system (CNS) have not improved significantly in the last decade. Immunotherapy as novel and efficacious treatment option in several other malignancies has failed in neuro-oncology likely due to the immunosuppressive property of the brain tissues. Glioblastoma (GBM) is the most aggressive malignant CNS neoplasm, while meningioma (MNG) is a mainly low grade or benign brain tumor originating from the non-glial tissues of the CNS. The aim of the current preliminary study is to compare the immune microenvironment of MNG and GBM as potential target in immunotherapy. Interestingly, the immune microenvironment of MNG and GBM have proved to be similar. In both tumors types the immune suppressive elements including regulatory T cells (Treg), tumor-associated macrophages (TAM) were highly elevated. The cytokine environment supporting Treg differentiation and the presence of indoleamine 2,3-dioxygenase 1 (IDO1) have also increased the immunosuppressive microenvironment. The results of the present study show an immune suppressive microenvironment in both brain tumor types. In a follow-up study with a larger patient cohort can provide detailed background information on the immune status of individual patients and aid selection of the best immune checkpoint inhibitor or other immune modulatory therapy. Immune modulatory treatments in combination with IDO1 inhibitors might even become alternative therapy for relapsed, multiple and/or malignant MNG or chemo-resistant GBM.

[4th Hungarian Breast Cancer Consensus Conference - Radiotherapy guidelines]. / IV. Emlorák Konszenzus Konferencia ­ Sugárterápiás irányelvek.

The radiotherapy (RT) expert panel revised and updated the RT guidelines accepted in 2016 at the 3rd Hungarian Breast Cancer Consensus Conference based on new scientific evidence. Radiotherapy after breast-conserving surgery (BCS) is indicated in ductal carcinoma in situ (St. 0), as RT decreases the risk of local recurrence (LR) by 50-60%. In early stage (St. I-II) invasive breast cancer RT remains a standard treatment following BCS. However, in elderly (≥70 years) patients with stage I, hormone receptor positive tumour hormonal therapy without RT can be considered. Hypofractionated whole breast irradiation (WBI) and for selected cases accelerated partial breast irradiation are validated treatment alternatives of conventional WBI. Following mastectomy RT significantly decreases the risk of LR and improves overall survival of patients having 1 to 3 or ≥4 positive axillary lymph nodes. In selected cases of patients with 1 to 2 positive sentinel lymph nodes axillary dissection can be substituted with axillary RT. After neoadjuvant chemotherapy (NAC) followed by BCS WBI is mandatory, while after NAC followed by mastectomy locoregional RT should be given in cases of initial stage III-IV and ypN1 axillary status.
