Phyllodes tumors of the breast. The treatment results for 340 patients from a single cancer centre.

PURPOSE: The primary treatment of choice for patients with phyllodes tumor of the breast (PTB) is surgery. Two major problems regarding the treatment of such patients remain unclear: what is the appropriate surgical margin and what role is played by adjuvant radiotherapy (ART). METHODS: The study provides a retrospective review of all patients with PTB treated between 1952 and 2013 at a single institute. The histology slides were re-examined based on WHO criteria. The clinical characteristics and therapy outcomes were obtained. The five-year survival with no evidence of disease (NED) was used as the end point. RESULTS: The study population comprised 340 women with PTB. Fifty-five percent of the patients were diagnosed with the benign, 11.8% with borderline and 33.2% with malignant PTB. All the patients received primary treatment with surgery (mastectomy-27.1%, and BCS- 72.9%). Local recurrence (LR) was found in 28 (9.1%) of these patients. Four patients with borderline and 8 with malignant PTB who were treated with BCS and had tumor-free margins < 1 cm received ART. None of these patients had LR and all survived 5 years NED. Of the 340 patients from our group, 294 (86.4%) survived five-years NED. CONCLUSION: The prognosis for benign PTB is excellent and can be cured with surgery alone. A sufficient margin would be 0.1 cm (data from the literature) or 0.2-0.4 cm (our study). We recommend application of ART for such patients but the role of ART in patients with borderline and malignant PTB treated with BCS and with surgical margin < 1 cm remains uncertain.

Treatment of Patients with Distant Metastases from Phyllodes Tumor of the Breast.

BACKGROUND: Here, the treatment methods and results of patients with phyllodes tumor of the breast (PT) with distant metastases at a single institution are presented. METHODS: A retrospective analysis was performed on a group of 295 patients with PT treated from 1952 to 2010. RESULTS: Distant metastases developed in 37 (12.5 %) patients; 3/160 (1.9 %) patients had benign PT, 6/36 (16.7 %) were considered borderline, and 28/99 (28.3 %) had malignant PT. Most frequently, the metastases were located in the lungs; 28 (75.7 %), bone 7 (18.9 %), brain 4 (10.8 %), and liver 2 (5.4 %). Metastases occurred on overage 21 months (2-57) after surgery. Patients with lung metastases were generally treated with monochemotherapy or polychemotherapy. In one patient Testosterone and in two patients resection of metastases combined with Doxorubicin were used. Patients with bones or brain metastases were treated with palliative radiotherapy only or combined with Doxorubicin. The mean survival (MS) from diagnosis of distant metastases (DM) was 7 months (2-17). The longest mean survival in patients with bones metastases was 11.8 months, the worst survival was for patients with brain metastases--2.8 months. Hormone therapy appeared to have low efficacy (MS: 2 months) as well as monochemotherapy (MS: 3-5 months). Improved MS was obtained using Doxorubicin (7 months) and Doxorubicin with Cisplatin, Cyclophosphamide, or Ifosfamide (9 months). CONCLUSION: The prognosis of patients with DM from PT is poor. The role of surgery and irradiation of such patients is very limited. There appears to be no role for the use of hormone therapy. This study showed that polychemotherapy with Doxorubicin and Ifosfamide suggest that it might be more effective than once thought.

Distant metastases from invasive lobular breast carcinoma classic type - treatment and prognosis.

INTRODUCTION: Invasive lobular carcinoma (ILC) comprises 4-15% of all malignant neoplasms of the breast. The "classical variant of ILC" (C-ILC) constitutes some 60-80% of this cancer. The main cause of treatment failures is dissemination observed in 8-38% patients The disant metastases (DM) are frequently localized in: bones, gastrointestinal tract, uterus, leptomeninges, and ovaries. The aim of this study was to present the methods and results of the treatment of patients with DM from the classical variant of ILC (C-ILC) at a single institution in Poland. MATERIALS AND METHODS: Between January 1983 and December 2004, 210 women with C-ILC of the breast were primarily treated surgically (mastectomy in 182 (86.7%) patients and breast conserving therapy in 28 (13.3%) patients). Then adjuvant therapy (radiotherapy, chemotherapy, and hormonotherapy) was applied according to presence of clinical indications. RESULTS: The present study focused on a group of 41 patients with a median age of 59 that died with DM from C-ILC during the ten-year follow-up. This failure developed on average 65 months (3-186) after surgery of ILC. The most frequently DM developed: bones (39.1%), GI (small bowell, stomach, colon, rectum) - 31.8%, and reproductive organs (ovary, uterus) - 19.1%. In therapy of DM, different configuration surgery, radiotherapy, and chemo-hormonotherapy were used. The median survival after the diagnosis of DM was connected with localization of distant metastases. CONCLUSION: Patients with classic variant of infiltrate lobular cancer of breast should be regularly follow-up, which could permit early diagnosis of distant metastases and improve treatment results.

Toxicity of concurrent chemoradiotherapy for locally advanced cervical cancer.

AIM OF THE STUDY: The analysis of acute and late toxicity of concurrent chemoradiotherapy (CCRT) for locally advanced cervical cancer (LACC) based on review of 120 patients treated in Centre of Oncology in Krakow between 2001 and 2007. MATERIALS AND METHODS: Medium age of the patients was 52 years (43-66). Overall, 12 patients (10.0%) were in Stage IB2, 54 (45.0%) in Stage II, 43 (35.8%) in Stage III, and 11 (9.2%) in Stage IVA. Squamous cell carcinoma was present in 114 (95.0%) patients. Well-differentiated (grade 1) tumour was found in 39 (32.5%) patients, moderately differentiated (grade 2) in 41 (34.2%), and poorly differentiated (grade 3) in 40 (33.3%). Karnofsky performance status score was 70 in 72 (60.0%) patients, and 80-90 in 48 (40%). External radiation therapy was delivered with high-energy six to 15 MV photon beams using four-field brick technique. The total dose of 50 Gy was given in 25 fractions within five weeks using standard fractionation. Concurrently with external radiotherapy, six cycles of chemotherapy were administered to all the patients as an intravenous infusion of once-weekly cisplatin 40 mg/m2. On completion of external beam radiotherapy, low-dose rate brachytherapy with tandem and two colpostats was performed to deliver the dose of 40 Gy to point A in two 20 Gy insertions at weekly intervals. RESULTS: Of the 120 patients in the investigated group, 78 (65%) were disease-free for five years. Symptoms of acute treatment-related toxicity grade 3 or 4 (WHO) occurred in 21.6% of patients including leucopoenia in 7.5%. anaemia in 5.0%, nausea and vomiting in 3.3%, diarrhea in 5.0%, and urinary tract infection in 0.8%. Full planned treatment (teleradiotherapy + chemotherapy + brachytherapy) completed 78.3% of the group; full planned radiotherapy without full chemotherapy completed 20% of the patients. Late treatment complications of grade 3 or 4 were observed in two (1.6%) patients (narrowing of large intestine requiring surgery and recto-vaginal fistula). CONCLUSIONS: In patients with LACC treated with CCRT, the most frequent acute toxic effects include: haematological disorders (leucopoenia, anaemia), gastrointestinal disorders (nausea and vomiting, diarrhea), vulvo-vaginal disorders, and urinary tract infection. The most frequent late toxic effects included: rectal bleeding, bowel complications requiring surgery, stenosis or recto-vaginal fistula, and haematuria.

Salvage prostate HDR brachytherapy combined with interstitial hyperthermia for local recurrence after radiation therapy failure.

PURPOSE: The aim of the present retrospective study is to evaluate toxicity and early clinical outcomes of interstitial hyperthermia (IHT) combined with high-dose rate (HDR) brachytherapy as a salvage treatment in patients with biopsy-confirmed local recurrence of prostate cancer after previous external beam radiotherapy. PATIENTS AND METHODS: Between September 2008 and March 2013, 25 patients with local recurrence of previously irradiated prostate cancer were treated. The main eligibility criteria for salvage prostate HDR brachytherapy combined with interstitial hyperthermia were biopsy confirmed local recurrence and absence of nodal and distant metastases. All patients were treated with a dose of 30 Gy in 3 fractions at 21-day intervals. We performed 62 hyperthermia procedures out of 75 planned (83 %). The aim of the hyperthermia treatment was to heat the prostate to 41-43 °C for 60 min. Toxicity for the organs of the genitourinary system and rectum was assessed according to the Common Terminology Criteria for Adverse Events (CTCAE, v. 4.03). Determination of subsequent biochemical failure was based on the Phoenix definition (nadir + 2 ng/ml). RESULTS: The median age was 71 years (range 62-83 years), the median initial PSA level was 16.3 ng/ml (range 6.37-64 ng/ml), and the median salvage PSA level was 2.8 ng/ml (1.044-25.346 ng/ml). The median follow-up was 13 months (range 4-48 months). The combination of HDR brachytherapy and IHT was well tolerated. The most frequent complications were nocturia, weak urine stream, urinary frequency, hematuria, and urgency. Grade 2 rectal hemorrhage was observed in 1 patient. No grade 3 or higher complications were observed. The 2-year Kaplan-Meier estimate of biochemical control after salvage treatment was 74 %. The PSA in 20 patients decreased below the presalvage level, while 11 patients achieved a PSA nadir < 0.5 ng/ml. All patients are still alive. Of the 7 patients who experienced biochemical failure, bone metastases were found in 2 patients. CONCLUSION: IHT in combination with salvage HDR brachytherapy is a well tolerated and effective treatment.

Interstitial hyperthermia of the prostate in combination with brachytherapy : An evaluation of feasibility and early tolerance.

OBJECTIVE: A retrospective study to evaluate the feasibility and toxicity of interstitial hyperthermia (IHT) combined with high-dose-rate (HDR) brachytherapy as the initial treatment for low- and intermediate-risk prostate cancer, and as a salvage therapy in previously irradiated patients with local recurrence. PATIENTS AND METHODS: Between 18 December 2008 and 5 September 2012, 73  prostate cancer patients were treated with interstitial HDR brachytherapy of the prostate combined with IHT. In 54 patients this was the initial therapy for prostate cancer, while the other 19 were treated for local recurrence after previously undergoing external beam radiotherapy (EBRT). Toxicity for the organs of the genitourinary system and rectum was assessed according to the Common Terminology Criteria for Adverse Events (CTCAE) v. 4.03 within 3 months after treatment. RESULTS: Median follow-up was 15 months (range 3-46). The combination of HDR brachytherapy and IHT was well tolerated. The toxicity profile was similar to that of HDR brachytherapy when not combined with hyperthermia. The most common minor complications were urinary frequency (grade 1: 37 %; grade 2: 22 %), nocturia (three times per night: 29 %; four- or more times per night: 20 %) and transient weakening of the urine stream (grade 1: 36 %; grade 2: 11 %). No early rectal complications were observed in the patient group and the severity of genitourinary toxicity was only grade 1-2. CONCLUSION: Early tolerance of IHT in combination with HDR brachytherapy is good. Further prospective clinical studies should focus on the effects of combining IHT with HDR brachytherapy and the influence of this adjuvant therapy on biochemical disease-free survival, local control and overall survival.

Effectiveness of radiotherapy in patients with primary invasive vaginal carcinoma.

INTRODUCTION: The aim of the study was to present an institutional experience in radiation therapy of primary invasive vaginal carcinoma (PIVC) patients treated in the Krakow Branch of Centre of Oncology, with special regard to treatment effectiveness and failure causes. MATERIALS AND METHODS: Between February 1967 and January 2007, 162 PIVC patients were treated with radical radiotherapy in the Krakow Branch of Centre of Oncology, Maria Sklodowska-Curie Memorial Institute. Twenty-seven (16.7%) patients in Stage I(0) were treated with intracavitary brachytherapy alone; for 127 (78.4%) patients in Stage I(0)- IV(0) intracavitary brachytherapy was combined with external radiation therapy; and eight (4.9%) patients in Stage IVA(0) were given only external radiotherapy. RESULTS: In the investigated group of 162 patients, five-year disease-free survival was observed in 46.3% of the cases. Patient age and FIGO Stage of neoplastic disease were independent prognostic factors. Five-year disease-free survival was observed in 64.9% of the patients < 60 years of age and only in 30.7% > or = 60 years of age; and in 62.3% of PIVC patients in Stages I and II(0) as compared to 19.7% of Stages III(0) and IV(0) cases. Among 78 patients who died of PIVC, in 60 (76.9%) cases the cause of death was locoregional failure; in six (7.7%), locoregional failure and distant metastasis; and in 12 (15.4%), distant metastasis. CONCLUSIONS: Radiotherapy is effective treatment for PIVC patients. Age below 60 years and non-advanced neoplastic disease were independent favourable prognostic factors in the investigated group of patients. The primary cause of treatment failure was failure to achieve locoregional disease control.

All patients survived 10 years with no evidence of disease.

Multimodality treatment of noninflammatory stage IIIb breast cancer.

BACKGROUND AND OBJECTIVES: The 1990s have established the contribution of multimodality therapy in the management of IIIb noninflammatory breast cancer (IIIb NIBC), by reducing the odds of recurrence and death. METHODS: A total of 300 women with IIIb NIBC received a multimodality therapy. The treatment consisted of neoadjuvant chemotherapy [FAC (5-fluorouracil, Adriamycin, cyclophosphamide) regimen], radical (Halsted) mastectomy or modified (Patey mastectomy), postoperative radiotherapy, and adjuvant chemohormone therapy [FAC regimen + cyclophosphamide, 5-fluorouracil and methotrexate (CMF) regimen or Tamoxifen]. RESULTS: Complete or partial clinical response (CR or PR) after neoadjuvant chemotherapy was obtained in 83% patients. Ninety-nine patients (33%) survived 5 years without evidence of disease (NED). The uni- and multivariate analyses factors that had significant influence on the treatment results were: clinical response to neoadjuvant chemotherapy, pathological tumor size, and microscopical status of the axillary lymph nodes. CONCLUSIONS: We conclude that neoadjuvant FAC regimen chemotherapy is very effective in producing objective tumor regression and offers the benefit of radical mastectomy to patients with previously unresectable IIIb NIBC.

[The role of radiotherapy in the management of benign lymphoepithelial lesions]. / Rola radioterapii w leczeniu benign lymphoepithelial lesion.

Benign lymphoepithelial lesion (BLL) is observed as a diffuse or nodular enlargement of major salivary gland. In 80% it appears in woman in the sixth and seventh decade. The histopathologic appearance consist of a triad of parenchymatous atrophy, interstitial lymphocytic infiltration and epimyoepithelial islands. This disease co-exists in 50% of cases with connective tissue disorders. In patients with BLL the risk of the development of a malignant lymphoma may be as high as 40:1 in comparison to the control group. From 1960 to 1991 ten women with BLL in salivary glands were treated in Oncology Centre in Kraków. The disease was localized in parotid glands (8 pts), in submandibular glands (1 pt) and in parotid and submandibular gland (1 pt). In this group 3 patients were treated for the rheumatoid arthritis and in 1 women presented symptoms of Sjögren' syndrome. Exclusive surgical treatment was performed in 2 patients, 7 patients were treated with irradiation, and 1 patient received combined therapy: surgery and radiotherapy. The doses of irradiation were from 12 to 36 Gy given in 6 to 18 fractions. Complete remission was observed in 2 patients who received only surgical treatment. In group of 8 patients treated with irradiation and surgery and irradiation we have observed local control in six women after 1 series and in two women after 2 series of irradiation. During the observation malignancies developed in 4 patients between 11 to 39 months after radiotherapy. One patient developed cancer of salivary gland. In remaining 3 patients it was observed malignant lymphomas. Our results of therapy of BLL in salivary gland are similar to presented by the other authors and indicate the efficiency of local (surgical or irradiation) treatment.

[The prognostic significance of impaired vocal cord motility in patients with stage II glottic cancer treated with radiotherapy]. / Prognostyczne znaczenie ograniczenia ruchomosci faldów glosowych u chorych na raka glosni w II stopniu zaawansowania leczonych napromienianiem.

Eighty-five patients with stage II glottic laryngeal cancer were treated with radiotherapy in Center of Oncology in Kraków between 1973 and 1989. Fifty-five patients were irradiated with 60Co unit, 30 with mixed photon--electron beam. The 5-year survival rates without evidence of disease after the radiotherapy only were 65.9%, after the radiotherapy and surgery for recurrences--76.5%. The sex, age, local extension of primay tumour and vocal cord mobility were evaluated in a uni- and multivariate analysis of prognostic factors. For the end-point of 5-year survival without evidence of disease no statistically significant relationship was found between results and analysis variables, especially between survival and impaired cord mobility.

Six hundred and thirty patients with stage I and II glottic and supraglottic laryngeal cancer were treated with radiotherapy in Center of Oncology in Kraków between 1973 and 1989. The 5-year NED survival rates after the radiotherapy only were 79%, after the radiotherapy and surgery for reccurrences--87.1%. Gender is not a prognostic factor in early stage laryngeal cancer treated with radiotherapy.

[Prognostic factors in patients with early stages of supraglottic cancer treated by radiotherapy]. / Czynniki prognostyczne u chorych na niezaawansowanego raka górnego pietra krtani leczonych napromienianiem.

Three hundred patients with early stage supraglottic cancer were treated with radiotherapy in Center of Oncology in Kraków between 1973 and 1989. The 5-year NED survival rates after the radiotherapy only were 82.9% in stage I, and 70%in stage II cancer, after the radiotherapy and surgery for recurrences--90% and 75% respectively. The stage and tumor site were an important prognostic factors in the treated group of patients.

Pure immature teratoma of the ovary: analysis of 22 cases.

Between 1970 and 1991, 22 patients with pure immature teratoma were treated at the Center of Oncology in Krakow. Sixteen (72.7%) patients had stage I, four (18.2%) stage II, and two (9.1%) stage III of disease, nine (40.9%) patients had grade 1, 11 (50%) grade 2, and two (9.1%) grade 3 tumors. Eight stage Ia, grade 1 patients were treated with surgery only, the remaining 14 (63.6%) received postoperative chemotherapy. Five-year NED (no evidence of disease) survival was achieved in 81.8% of patients. Out of 16 stage I patients, 15 (93.8%) survived 5-year NED, out of six stage II and III, three (50%) patients only survived this period. We cured all grade 1 patients, and 81.8% (9/11) grade 2; two grade 3 patients died because of tumors. We also cured all six stage Ia patients, treated with unilateral salpingo-oophorectomy (with or without chemotherapy), and all eight stage Ia grade 1 patients treated with surgery only.

Two-hundred and fifty patients presenting with a stage I-II cancer of the supraglottic larynx were definitively treated with irradiation. The 5-year disease-free survival rate is 76%. Multivariate analysis reveals that the only statistically significant prognostic parameters are clinical stage (I versus II), and tumour site (epilarynx versus supraglottis).

[Radiation therapy in glottic laryngeal carcinoma stage. I. Results and analysis of prognostic factors]. / Teleradioterapia raka glosni w I. zaawansowania. Wyniki leczenia I analiza czynników prognostycznych.

Two hundred and forty-five patients with stage I glottic laryngeal cancer were treated with radiotherapy in Center of Oncology in Kraków between 1973 and 1988. One hundred and fifty-five patients were irradiated with Co-60 unit, 90 patients with mixed photon-electron beam. The 5-year NED survival rates after the radiotherapy only were 85.3%, after the radiotherapy and surgery for recurrences--95.1%. The sex, age, local extension of primary tumor (T1a vs. T1b), location of the tumor on true vocal cord and involvement of anterior commissure were evaluated in a uni- and multivariate analysis of prognostic factors. For the end-point of 5-year NED survival no statistically significant relationship was found between results and analysis variables.
