PURPOSE: Male breast cancer (MBC) is a rare, but increasingly common disease, and lacks prospective studies. Collaborative efforts are needed to understand and address MBC, including its prognosis, in different countries. METHODS: We retrospectively reviewed the clinical, histopathological, and molecular-genetic characteristics, treatments, and survival outcomes of MBC diagnosed between 2007 and 2017 in the Czech Republic. Prognostic factors of overall survival (OS), recurrence-free interval (RFi), and breast cancer-specific mortality (BCSM) were analyzed and indirectly compared to international data. RESULTS: We analyzed 256 patients with MBC (median age 66 years), including 12% with de novo metastatic (M1). Of 201 non-metastatic (M0) patients, 6% were <40 years old, 29% had stage I, 55% were cN0, and 54% underwent genetic testing. Overall, 97% of tumors had estrogen receptor expression ≥10%, 61% had high Ki67 index, 40% were high-grade (G3), and 68% were luminal B-like (HER2-negative). Systemic therapies included endocrine therapy (90%) and chemotherapy (53%). Few (5%) patients discontinued adjuvant endocrine therapy for reasons other than disease relapse or death. Patients treated with aromatase inhibitors alone had significantly shorter RFi (P < .001). OS, RFi, and BCSM were associated with disease stage, T stage, N stage, progesterone receptor expression, grade, and Ki67 index. Median OS reached 122 and 42 months in M0 and de novo M1 patients, respectively. CONCLUSION: Due to the rarity of MBC, this study highlights important findings from real clinical practice. Although the number of patients with MBC with unfavorable features was higher in this Czech dataset than in international studies, the prognosis remains consistent with real-world evidence.

Volba optimálního terapeutického postupu u nemocných s karcinomem prsu představuje náročný úkol. Onemocnění je tvořeno celou řadou subtypů s rozdílnou biologickou charakteristikou a různou prognózou a může se vyskytovat i u žen staršího věku, pro které standardní terapeutické přístupy mohou znamenat významné zhoršení kvality života bez přínosu v přežití. Řada studií prokázala nejen pro tuto skupinu nemocných s časnými stadii karcinomu prsu různé možnosti redukce chirurgického výkonu i léčby zářením. Deeskalace radioterapie zahrnuje vynechání ozáření u vybraných pacientek, zkrácení délky léčby pomocí hypofrakcionace a ultrahypofrakcionace, snížení ozářeného objemu parciálním ozářením prsu. Za zásadní podmínku je nutná správná informovanost nemocné a možnost podílet se na rozhodování o volbě terapeutického postupu.
Choosing the optimal therapeutic strategy in patients with breast cancer is a challenging task. The disease comprises a number of subtypes having distinct biological characteristics and variable prognosis, and can occur in elderly women in whom standard therapeutic approaches may result in significant deterioration in their quality of life with no survival benefit. Numerous studies have shown various options for reducing the burden of surgery and radiotherapy not only for the group of patients at early stages of breast cancer. De-escalation of radiotherapy involves omitting radiation in selected patients, shortening the duration of treatment by using hypofractionation and ultra-hypofractionation, and reducing the irradiated volume by partial breast irradiation. It is essential for the patient to be properly informed and to be able to participate in the decision-making process on the therapeutic options.

The role of postmastectomy radiotherapy and regional nodal irradiation after radical mastectomy is defined in high-risk patients with locally advanced tumors, positive margins, and unfavorable biology. The benefit of postmastectomy radiotherapy in intermediate-risk patients (T3N0 tumors) remains a matter of controversy. It has been demonstrated that radiotherapy after breast-conserving surgery lowers the locoregional recurrence rate compared with surgery alone and improves the overall survival rate. In patients with four or more positive lymph nodes or extracapsular extension, regional lymph node irradiation is indicated regardless of the surgery type (breast-conserving surgery or mastectomy). Despite the consensus that patients with more than three positive lymph nodes should be treated with radiotherapy, there is controversy regarding the recommendations for patients with one to three involved lymph nodes. In patients with N0 disease with negative findings on axillary surgery, there is a trend to administer regional lymph node irradiation in patients with a high risk of recurrence. In patients treated with neoadjuvant systemic therapy and mastectomy, adjuvant radiotherapy should be administered in cases of clinical stage III and/or ≥ypN1. In patients treated with neoadjuvant systemic therapy and breast-conserving surgery, postoperative radiotherapy is indicated irrespective of pathological response.

Standardem léčby časných stadií karcinomu prsu je prs šetřící chirurgická léčba, kombinovaná s perioperační léčbou systémovou a pooperační radioterapií. Mastektomie se nadále provádí u pacientek, kterým nelze záchovnou operaci z léčebného či kosmetického hlediska doporučit. Jedná se často o lokálně či regionálně pokročilá onemocnění, kde po mastektomii prakticky vždy následuje adjuvantní radioterapie. S rekonstrukcí prsu po mastektomii se setkáváme stále častěji a tento trend bude dále narůstat i v budoucnosti. S pokroky v medicíně dochází k rozvoji jak chirurgických postupů samotné rekonstrukce, tak i technických možností radioterapie. Otázka správné kombinace a načasování rekonstrukce a adjuvantní radioterapie nadále vyvolává četné otázky, na které se snaží odpovědět následující přehledový článek.
Breast-conserving surgical treatment combined with perioperative systemic therapy and postoperative radiotherapy is the standard treatment for early-stage breast carcinoma. Mastectomy continues to be performed in patients in whom breast-conserving surgery cannot be recommended for therapeutic or cosmetic reasons. They often have locally or regionally advanced disease in which mastectomy is virtually always followed by adjuvant radiotherapy. Breast reconstruction following mastectomy is increasingly encountered, and this trend will continue to grow in the future. With advances in medicine, there has been progress in both the surgical procedures used in reconstruction and the technical aspects of radiotherapy. The issue of correct combination and timing of reconstruction and adjuvant radiotherapy continues to raise numerous questions which the present review article attempts to address.

Modern radiotherapy techniques are designed to permit reduced irradiation of healthy tissue, resulting in a diminished risk of adverse effects and shortened recovery times. Several randomized studies have demonstrated the benefits of increased dosage to the tumor bed area in combination with whole breast irradiation (WBI). Conventional WBI treatment following breast-conserving procedures, which required 5-7 weeks of daily treatments, has been reduced to 3-4 weeks when using hyperfractionated regimens. The dosage administration improves local control, albeit with poorer cosmesis. The method of accelerated partial breast irradiation (APBI) shortens the treatment period whilst reducing the irradiated volume. APBI can be delivered using intraoperative radiation, brachytherapy, or external beam radiotherapy. Currently available data support the use of external beam partial breast irradiation in selected patients. Modern radiotherapy techniques make it possible to achieve favorable cosmesis in most patients undergoing immediate breast reconstruction surgery, and studies confirm that current methods of external beam radiation allow an acceptable coverage of target volumes both in the reconstructed breast and in the regional lymphatic nodes.

Tumor biology plays a crucial role in the systemic treatment, specifically in HER2-positive tumors. Distinct biological behavior of breast cancer subtypes is associated with different rates of locoregional recurrence (LRR). HER2- positive breast cancer patients treated with surgery in combination with radiation, without trastuzumab have poor outcome, including high LRR. The efficacy of radiotherapy in HER-2-positive breast cancer appears to be associated with the expression of estrogen receptors. In patients with HER-2-positive breast cancer, studies conducted before the introduction of trastuzumab indicated higher benefit of adjuvant radiation in patients with hormone receptor-positive tumors compared to patients with tumors not expressing hormone receptors. The introduction of agents targeting HER-2 has transformed the management of these patients, resulting in improved outcomes. The data of clinical studies show that the administration of trastuzumab as part of a multimodality approach (with radiation based on standard guidelines) results in improved outcomes, including lower locoregional recurrence. The risk of cardiac toxicity associated with radiation to the heart and administration of potential cardiotoxic trastuzumab is not clear. In patients treated concomitantly with regional lymph node irradiation and anti-HER-2 agents after prior anthracycline-based chemotherapy minimizing the dose to the myocardium, e.g. respiratory gating or proton beam radiotherapy, have been suggested.
PURPOSE: This paper compares individual radiation therapy techniques used for prostate cancer and their benefits in clinical practice. METHODS: We retrospectively analyzed 921 patients with localized prostate tumors treated between 1997 and 2012. We divided the patients into four groups according to the selected treatment technique (conformal radiation therapy [3DCRT], intensity-modulated radiation therapy [IMRT], image-guided radiation therapy [IGRT], and volumetric-modulated arc therapy [VMAT]) and evaluated the incidence of acute and chronic gastrointestinal (GI) and genitourinary (GU) toxicity. RESULTS: The incidence of grade 2 or greater acute GU and GI toxicity was significantly higher among techniques other than IGRT (p˂0.001). We found the same results in the case of grade 3 or greater acute GU toxicity (p˂0.001). Grade 3 or higher acute GI toxicity occurred only in one patient treated by 3DCRT. Cumulative late GI toxicity of grade 2 or higher and grade 3 or higher was recorded over 3 years significantly more frequently among non-IGRT techniques as compared to IGRT (p˂0.001). As regards GU toxicity, we found significantly higher incidence only for grade 2 or higher (p˂0.001), not for grade 3 or higher. No occurrence of grade 4 toxicity was recorded. The greatest incidence of patients without acute and chronic GI/GU toxicity was recorded in connection with VMAT. CONCLUSION: IGRT demonstrated a pronounced reduction in acute and chronic GU and GI toxicity as compared to non-IGRT techniques in the treatment of localized prostate cancer.
