    Breast conserving surgery (BCS) followed by chemotherapy (CT{sub x}.) and radiation therapy (RT) is widely performed for the treatment of early breast cancer. This retrospective study was undertaken to evaluate our interim results in terms of failure patterns, survival and relative risk factors. From January 1999 through December 2003, 129 patients diagnosed with invasive breast cancer and treated with BCS followed by RT were subject to retrospective review. The median age of the patients was 45 years (age distribution, 27 {approx} 76 years). The proportions of patients according to their tumor, nodes, and metastases (TNM) stage were 65 (50.4%) in stage I, 41 (31.7%) in stage IIa, 13 (10.1%) in stage IIb, 9 (7.0%) in stage III, and 1 patient (0.8%) in stage IIIc. For 32 patients (24.8%), axillary node metastasis was found after dissection, BCS consisted of quadrantectomy in 115 patients (89.1%) and lumpectomy in 14 patients (10.6%). Axillary node dissection at axillary level I and II was performed for 120 patients (93%). For 7 patients (5.4%), only sentinel node dissection was performed with BCS. For 2 patients (1.6%) axillary dissection of any type was not performed. Postoperative RT was given with 6 MV X-rays. A tumor dose of 50.4 Gy was delivered to the entire breast area using a tangential field with a wedge compensator. An additional dose of 9 {approx} 16 Gy was given to the primary tumor bed areas with electron beams. In 30 patients (23.3%), RT was delivered to the supraclavicular node. Most patients had adjuvant CT{sub x}. with 4 {approx} 6 cycles of CMF (cyclophosphamide, methotrexate, 5-fluorouracil) regimens. The median follow-up period was 50 months (range: 17 {approx} 93 months). The actuarial 5 year survival rate (5Y-OSR) was 96.9%, and the 5 year disease free survival rate (5Y-DFSR) was 93.7%. Local recurrences were noted in 2 patients (true: 2, regional node: 1) as the first sign of recurrence at a mean time of 29.3 months after surgery. Five

    The low surgical cure rate in patients with stage III non-small cell lung cancer has prompted an exploration of multimodality treatment strategies. Mature results are presented from a phase II trial of accelerated hyperfractionated radiation therapy, concurrent paclitaxel/cisplatin chemotherapy and surgery for these patients. Between 1994 and 1997, 45 patients with surgically demonstrated stage III non-small cell lung cancer underwent induction treatment with a 96 h continuous cisplatin infusion (20 mg/m(2) per day) and a 24 h infusion of paclitaxel (175 mg/m(2)) given concurrently with accelerated hyperfractionated radiation therapy (1.5 Gy twice daily) to a total dose of 30 Gy. Induction was completed in ten treatment (12 total) days. Surgical resection was scheduled 4 weeks later with a second identical course of chemoradiotherapy given 4-6 weeks post-operatively, to a total radiation dose of 60-63 Gy. Thirty-five patients had stage III(A) disease and ten had stage III(B) disease (eight with N(3) tumors). Induction toxicity included nausea in 89%, dysphagia in 89%, and neutropenia tolerable despite significant myelosuppression. Locoregional control is excellent and survival is better than historical expectations. Patients downstaged to mediastinal node negativity have a prognosis similar to those with de novo stage I(B) and II disease. Distant metastases are the major cause of treatment failure.

    We evaluate the correlation of clinical staging on positron emission tomography-computed tomography (PET-CT) and pathologic staging and the prognostic value of PET-CT after induction chemotherapy in patients with locally advanced nonsmall cell lung cancer (NSCLC). We analyzed 42 cases of clinical stage IIIA-N2 NSCLC who receive 2 to 4 cycles of preoperative chemotherapy with or without radiation followed by curative resection. The maximum standard uptake value (SUVmax) of the suspected lesion on PET-CT was recorded. PET-CT findings after induction chemotherapy were compared with those of initial PET-CT and pathology after surgery. The accuracy of PET-CT in restaging of the primary tumor after induction chemotherapy was 50.0%. Eighteen (42.8%) of 42 patients were underestimated ycT stage, and 3 (7.1%) of 42 patients was overestimated ycT stage by PET-CT scan. The accuracy of PET-CT in restaging of the nodal disease was 71.4%. Six (14.3%) of 42 patients were underestimated ycN stage, and 6 (14.3%) of 42 patients were overestimated ycN stage as compared with pathologic staging. The 2-year overall survival (OS) and relapse-free survival (RFS) rate were 68.5% and 40.9%, respectively. Complete responders (ycT0N0M0) on PET-CT after induction chemotherapy had a significantly longer RFS time than did incomplete responders (28.3 vs 9.1 months, P = 0.021). Complete response on PET-CT after induction chemotherapy with or without radiation was a good prognosticator for RFS in stage IIIA-N2 NSCLC patients who received surgery. However, response evaluation on PET-CT after induction chemotherapy should be interpreted with caution due to its unacceptable accuracy.

    The sequential use of chemotherapy and surgery in the treatment of osteosarcoma developed in an empirical fashion without the benefit of investigations in animal models. The MGH-OGS murine osteosarcoma is a transplantable tumor that resembles the human disease with respect to histology, local invasiveness, metastatic characteristics, tumor ploidy, and its response to chemotherapy. We have used this tumor model to investigate the efficacy of preoperative, perioperative, and postoperative chemotherapy on the development of pulmonary metastases in three different experimental protocols. In each experimental design, perioperative chemotherapy demonstrated a significant advantage in preventing systemic relapse.

    Full Text Available Chemoradiotherapy is increasingly used in advanced laryngeal cancers. Failures are generally managed by surgery. They include histologically confirmed recurrent or residual disease or a symptomatic life threatening treatment sequelae. Tumour recurrence or residivism can be managed by chemotherapy when radical surgery is either refused by the patient or if the general condition of the patient do not permit it. However surgery becomes inevitable when life threatening treatment sequelae like absolute pharyngo-oesophageal stricture and aspiration sets in.

    Successful therapeutic interventions to prevent disease progression in patients with nonmetastatic osteosarcoma have included surgery with adjuvant chemotherapy. Presurgical chemotherapy has been advocated for these patients because of putative improvement in event-free survival (EFS). The advantages of presurgical chemotherapy include early administration of systemic chemotherapy, shrinkage of primary tumor, and pathologic identification of risk groups. The theoretic disadvantage is that it exposes a large tumor burden to marginally effective chemotherapy. The contribution of chemotherapy and surgery timing has not been tested rigorously. Between 1986 and 1993, we conducted a prospective trial in patients with nonmetastatic osteosarcoma who were assigned randomly to immediate surgery or presurgical chemotherapy. Except for the timing of surgery (week 0 or 10), patients received 44 weeks of identical combination chemotherapy that included high-dose methotrexate with leucovorin rescue, doxorubicin, cisplatin, bleomycin, cyclophosphamide, and dactinomycin. One hundred six patients were enrolled onto this study. Six were excluded from analysis. Of the remaining 100 patients, 45 were randomly assigned to immediate chemotherapy, and 55 were randomly assigned to immediate surgery. Sixty-seven patients remain disease-free. At 5 years, the projected EFS +/- SE is 65% +/- 6% (69% +/- 8% for immediate surgery and 61% +/- 8% for presurgical chemotherapy; P =.8). The treatment arms had similar incidence of limb salvage (55% for immediate surgery and 50% for presurgical chemotherapy). Chemotherapy was effective in both treatment groups. There was no advantage in EFS for patients given presurgical chemotherapy.

    Full Text Available Complementary therapies, notably natural health products such as herbs and vitamins, are frequently used by cancer patients receiving chemotherapy and radiation therapy. There is much controversy as to whether these natural health products should be taken during conventional cancer treatments. Supporters of this practice cite beneficial effects of the antioxidant properties, while opponents are concerned about the potential for natural health product-chemotherapy/radiation related negative interactions. This involves understanding the role and effect on metabolizing enzymes. This review will highlight the present evidence for both the beneficial and negative consequences of the use of natural health products during chemotherapy and radiation therapy.

    Full Text Available Myoepithelial carcinoma (malignant myoepithelioma of the breast is a rare tumor, for which only a limited number of reports have been published. Most of the reports emphasized diagnosis and pathology but not biological behavior and treatment. We report a 61-year-old patient with breast myoepithelial carcinoma who developed locoregional and distant metastases and received many chemotherapy regimens. She presented with an elastic hard mass of the left breast. Breast conserving surgery was performed as part of both diagnosis and treatment. From the results of histological and immunohistochemical examinations, this case was considered to be a myoepithelial carcinoma. Fifteen months after the completion of adjuvant radiotherapy, distant metastasis of the left parasternal lymph node metastasis developed. She was treated by further excision and received a total of four regimens of chemotherapy including a combination of doxorubicin and cyclophosphamide. She received chemotherapy for 20 months after the diagnosis of metastasis.

    Peritoneal surface malignancies are generally associated with poor prognosis.In daily clinical routine,systemic chemotherapy is still considered the only reasonable therapy despite of encouraging results of cytoreductive surgery (CRS) along with intraperitoneal hyperthermic chemotherapy (HIPEC).The Achilles heel of CRS and HIPEC is appropriate patient selection and precise surgical technique preventing patients from excessive morbidity and mortality.Given these findings,new concepts of second look surgery for high risk patients allow detection of peritoneal spread ahead of clinical symptoms or presence of peritoneal masses reducing perioperative morbidity.In addition,personalized intraperitoneal chemotherapy might further improve outcome by appreciating individual tumor biology.These days,every physician should be aware of CRS and HIPEC for treatment of peritoneal surface malignancies.Since there is now sufficient data for the superiority of CRS and HIPEC to systemic chemotherapy in selected patients,our next goal should be providing this strategy with minimal morbidity and mortality even in the presence of higher tumor load.

    Cytoreductive surgery and Hyperthermic Intraperitoneal Chemotherapy have achieved good long-term results in patients with complete surgical eradication of their peritoneal dissemination but at the expense of significant perioperative morbidity and mortality. The high complication rate has been attributed to the steep learning curve associated with this procedure. We report on the current literature regarding the learning curve for this procedure and the key components that determine the success in learning this new skill.

    Forty-seven patients with intrapelvic recurrent rectal cancer were prescribed radiation alone (17 cases), radiation and chemotherapy (18 cases) or radiation with hyperthermia (12 cases) from 1989 to 1995. To discuss efficacies and disadvantages of these combined therapies, tumor response rate, pain control rate, duration of tumor control and pain control, and influence on patients` survival were evaluated. Radiation was delivered to the whole pelvis. Mean total dose was 45.5 Gy (1.5-2 Gy/fraction). Chemotherapy consisted 5-FU or CDDP and ADM. Hyperthermia were added 3-6 times concomitantly to the radiation. In all patients receiving more than 30 Gy radiation, tumor response rate was 56.8%. Tumor response rates were 35.3%, 43.7% and 41.7% in the radiation alone group, radiation and chemotherapy group and radiation with hyperthermia group respectively. Radiation combined chemotherapy was more effective for the tumor less than 5 cm diameter than radiation alone. In cases receiving over 50 Gy radiation, combined treatments were more effective than radiation alone. Pain relief was obtained in 75.9% of patients and there were no difference between three treatment groups. Tumor control was significantly prolonged in combined groups. Median survival periods were 6, 10 and 7 months for radiation alone, radiation and chemotherapy, and radiation with hyperthermia respectively. In PR cases and for tumors under 5 cm in diameter, there were no difference between three groups. In cases receiving over 50 Gy radiation, survival period was prolonged in radiation with hyperthermia. Fourteen patients developed acute toxicity (Leucopenia) and late complication due to bowel obstruction. The incidence of bowel complication was 27.8% for radiation and chemotherapy and 33.3% for radio-hyperthermia, while 17.6%, significantly low percentage, for radiation alone. Bowel obstruction may occur positively correlated with postsurgical adhesions and infections at initial surgery. (K.H.)

    A 29-year-old man presented with acute glomerulonephritis five weeks following completion of combined chemotherapy (bleomycin-vinblastine) and abdominal radiation for testicular carcinoma. There was no evidence for a post-infectious cause or a systemic collagen disorder. The renal biopsy showed changes consistent with radiation nephritis. The combined radiation and chemotherapy may have, by additive or synergistic action, caused the early appearance of radiation nephritis.

    A 61-year-old man underwent amputation of the rectum for advanced lower rectal cancer in April 2005. UFT-E granules were administered orally daily at 400 mg/body/day following surgery. He developed perineal pain and perineal discharges following an increase the CEA level in April 2006. PET revealed a tumor in the perineum and multiple lung metastases. Chemotherapy with mFOLFOX 6 for 8 courses and FOLFIRI 2 for 4 courses were administered since July in 2006. Although CT revealed a the reduction in multiple lung metastases, CEA was increased to over a maximum 109, high fever continued and the pinealtumor was enlarged in December 2006. The patient underwent resection of the perinealmass, but he developed perinealsevere pain and perinealdischarge. So radiotherapy of the pelvic region was given at a total dose of 40 Gy(given 2 Gy each fragment)followed by administration of FOLFIRI 2 for 12 courses. After chemoradiotherapy, the CEA level was remarkably decreased. PET could not detect any mass in lung fields and revealed a little accumulation in the pelvic region. Chemotherapy with FOLFIRI 2 is administered monthly now, and the CEA level has been within the normal range since July of 2007. The pineal pain and pineal discharge disappeared, so the quality of life has improved dramatically.

    Full Text Available Esthesioneuroblastoma (ENB is an uncommon aggressive malignant intranasal neoplasm that originates from neural crest cells of the olfactory epithelium. Although local invasion to the sinuses is common, spinal metastasis of ENB is rare with only 28 documented cases involving the spine spinal cord, or leptomeninges. We report a case of ENB with multiple drop metastases to the cervical and thoracic spine, and review the patient’s disease, medical history, and multiple interventions during a span of 15 years following the initial cranial resection. Despite aggressive multiple surgical resections, radiation, and chemotherapy, the tumor had significant progression and recurrence. The literature is reviewed, followed by a discussion of the natural progression of the disease and various reported interventions. Although a combination of surgery with chemotherapy and radiation therapy has been recommended, no definitive management has been established for ENB. Further research is needed to determine decisive treatment for metastatic ENB to the spine.

    The overall cure rate of locally advanced non-small cell lung carcinoma (NSCLC) remains poor. Although there have been encouraging reports of preoperative use of chemotherapy, more recent trend is the trimodal approach of radiation, chemo, and surgical-therapies. With the trimodal therapy, increased tumor response and resectability are reported, however, there are increased treatment related side effects. It was observed that a relatively small dose of radiation given prior to induction chemotherapy greatly enhanced the tumor response to the chemotherapy without increased toxicity. A total of 18 patients (8 3. A and 10 3.B) were initially given 20 Gy of radiation therapy in 10 fractions and then received 2 courses of Taxol combination chemotherapy. The overall response rate was 83% (15/18) and 13 out of 18 patients underwent surgery. There was one postoperative death (not therapy related). It is speculated that the small dose of radiation therapy may have sensitized the tumor to subsequent chemotherapy, and it was suggested a new hypothesis of radiation therapy induced chemotherapy sensitization.

    In August 1982, a 44-year-old man was diagnosed as having rectal cancer, histologically diagnosed as well differentiated adenocarcinoma, and abdominoperineal resection and colostomy were performed. Postoperatively, he received chemotherapy with mitomycin C up to a total dose of 100 mg. In September 1986, lung metastasis occurred and he was treated with a combination chemotherapy consisting of cisplatin, pirarubicin and 5-fluorouracil. In the following year, radiation treatment (total: 6900 rad) was given for a recurrent pelvic lesion. Peripheral blood on April 30, 1988, showed anemia, thrombocytopenia and appearance of myeloblasts, and a diagnosis of acute myelogenous leukemia (FAB: M1) was made. Combination chemotherapy (including aclarubicin, vincristine, behenoyl ara-C, daunorubicin, 6-mercaptopurine, cytarabine, etoposide and prednisolone) failed to induce remission and the patient died in June 1988. This case was thought to be one of secondary leukemia occurring after chemotherapy and radiation treatment for rectal cancer. This case clearly indicates the need for a careful follow-up of long-term survivors who have received cancer therapy. (author).

    Severe stomatitis is a common problem encountered during either radiation therapy or chemotherapy. Most therapeutic regimens are empirical, with no scientific basis. The purpose of this study is to determine the efficacy of various topical solutions in the treatment of radiation- or chemotherapy-induced stomatitis. Eighteen patients were entered into a prospective double-blinded study to test several topical solutions: (1) viscous lidocaine with 1% cocaine; (2) dyclonine hydrochloride 1.0% (Dyclone); (3) kaolin-pectin solution, diphenhydramine plus saline (KBS); and (4) a placebo solution. Degree of pain relief, duration of relief, side effects, and palatability were evaluated. The results showed that Dyclone provided the most pain relief. Dyclone and viscous lidocaine with 1% cocaine provided the longest pain relief, which averaged 50 minutes This study provides objective data and defines useful guidelines for treatment of stomatitis.

    Purpose: The goal of this study was to evaluate dosimetric parameters, acute toxicity, pathologic response, and local control in patients treated with preoperative intensity-modulated radiation therapy (IMRT) and concurrent chemotherapy for localized gastric adenocarcinoma. Methods: Between November 2007 and April 2010, 25 patients with localized gastric adenocarcinoma were treated with induction chemotherapy, followed by preoperative IMRT and concurrent chemotherapy and, finally, surgical resection. The median radiation therapy dose was 45 Gy. Concurrent chemotherapy was 5-fluorouracil and oxaliplatin in 18 patients, capecitabine in 3, and other regimens in 4. Subsequently, resection was performed with total gastrectomy in 13 patients, subtotal gastrectomy in 7, and other surgeries in 5. Results: Target coverage, expressed as the ratio of the minimum dose received by 99% of the planning target volume to the prescribed dose, was a median of 0.97 (range, 0.92-1.01). The median V{sub 30} (percentage of volume receiving at least 30 Gy) for the liver was 26%; the median V{sub 20} (percentage of volume receiving at least 20 Gy) for the right and left kidneys was 14% and 24%, respectively; and the median V{sub 40} (percentage of volume receiving at least 40 Gy) for the heart was 18%. Grade 3 acute toxicity developed in 14 patients (56%), including dehydration in 10, nausea in 8, and anorexia in 5. Grade 4 acute toxicity did not develop in any patient. There were no significant differences in the rates of acute toxicity, hospitalization, or feeding tube use in comparison to those in a group of 50 patients treated with preoperative three-dimensional conformal radiation therapy with concurrent chemotherapy. R0 resection was obtained in 20 patients (80%), and pathologic complete response occurred in 5 (20%). Conclusions: Preoperative IMRT for gastric adenocarcinoma was well tolerated, accomplished excellent target coverage and normal structure sparing, and led to appropriate

    The objective of the study is to determine whether surgery influences the outcome of stage IV ovarian cancer. The study design is as follows: From May 1995 to December 2000, 129 patients with FIGO stage IV ovarian cancer, recruited in 42 centers, were prospectively included in GINECO first-line randomized studies of platinum-based regimens with paclitaxel administered simultaneously or sequentially. In all, 109 were eligible for this study. Standard peritoneal cytoreductive surgery was defined as a procedure including at least total hysterectomy, bilateral salpingo-oophorectomy, omentectomy, and peritoneal debulking. Surgery was considered optimal if residual lesions were smaller than 1 cm. The Kaplan-Meier method was used to compare survival. Initial abdominopelvic cytoreductive surgery was considered standard in 55 (54%) patients. Abdominopelvic surgery was optimal in 29 patients and nonoptimal in 26. Twenty-two (22%) patients had a simple biopsy, and 25 (24%) patients underwent substandard surgery. Twenty-two of these 47 patients without initial standard surgery underwent a second surgical procedure, and 17 of the 22 patients completed standard surgery. The median overall survival time in the entire population was 24.3 months (95% confidence interval [CI], 19.5-29.1 months). Patients treated without a cytoreductive surgical procedure had significantly worse median survival (15.1 months; 95% CI, 5.4-24.9 months) than patients who had optimal primary surgery (22.9 months; 95% CI, 15.6-30.1 months), nonoptimal primary surgery (27.1 months; 95% CI, 21.2-32.9 months), or neoadjuvant chemotherapy followed by surgery (45.5 months; 95% CI, 23.5-67.5 months) (P= .001). In conclusion, this study shows a significant benefit of debulking surgery in stage IV ovarian cancer patients who responded to neoadjuvant chemotherapy. Neoadjuvant chemotherapy can help to select patients for surgery.

    Purpose: To evaluate the efficacy and toxicity in patients with recurrence of cervical cancer treated with radiotherapy and simultaneous chemotherapy. Patients and methods: Between 1987 and 2001, 24 patients with recurrent cervical carcinoma were treated with concurrent chemoradiotherapy. Nine patients had incomplete tumor resection prior to radiation therapy. Irradiation was delivered to a total dose of 60 Gy, in three patients with central recurrence supplemented by brachytherapy. One patient was treated with brachytherapy alone. Simultaneous chemotherapy was done as a combined therapy of 5-fluorouracil-(5-FU, 600 mg/m{sup 2}/d1-5, 29-33) and cisplatin (20 mg/m{sup 2}/d1-5, 29-33; 16/24 patients) or of 5-FU (1,000 mg/m{sup 2}/d1-5, 29-33) and mitomycin C (10 mg/m{sup 2}/d2, 30; 1/24 patients). Cisplatin alone (25 mg/m{sup 2}/d1-5) and carboplatin alone (800 mg/m{sup 2}/d1-5) were administered in 5/24 patients (21%) and 2/24 patients (8%). Results: The 5-year local recurrence-free survival rate was 37%, disease-free survival 33%, and overall survival 34%. Grade 3 toxicity (NCI-CTC grade 3) occurred mainly as diarrhea (38%), leukopenia (33%), and nausea (21%). Severe toxicity (grade 4) was not seen in any of the patients. Conclusion: Radiation therapy with simultaneous chemotherapy for recurrences of cervical cancer is an effective treatment with acceptable toxicity. (orig.)

    Breast conservative surgery after neoadjuvant chemotherapy intends to remove any residual tumor with negative margins. The purpose of this study was to analyze the preoperative clinical-pathological factors influencing the margin status after conservative surgery in breast cancer patients receiving neoadjuvant chemotherapy. A retrospective study of 91 breast cancer patients undergoing neoadjuvant chemotherapy (92 breast lesions) during the period 2006 to 2013. A Cox regression analysis to identify baseline tumor characteristics associated with positive margins after breast conservative surgery was performed. Of all cases, 71 tumors were initially treated with conservative surgery after neoadjuvant chemotherapy. Pathologic exam revealed positive margins in 16 of the 71 cases (22.5%). The incidence of positive margins was significantly higher in cancers with initial size >5cm (P=.021), in cancers with low tumor grade (P=.031), and in patients with hormone receptor-positive cancer (P=.006). After a median follow-up of 45.2 months, 7 patients of the 71 treated with conservative surgery had disease recurrence (9.8%). There was no significant difference in terms of disease-free survival according to the margin status (P=.596). A baseline tumor size >5cm, low tumor grade and hormone receptor-positive status increase the risk for surgical margin involvement in breast conservative surgery after neoadjuvant chemotherapy.

    The standard treatment for an invasive bladder cancer is radical surgery; however, the quality of life of the patients who undergo total cystectomy is unfavorable even when the ileal conduits were constructed. We carried out a bladder-conserving treatment for 8 bladder cancer patients by using a hyperfractionated radiotherapy together with low dose of cis-platinum or carboplatinum daily as a radiosensitizer following trans-urethral tumor resection and neoadjuvant chemotherapy. Cystoscopic findings and biopsies at one month after completing radiation showed complete remission (CR) and partial response (PR) for 5 and 3 patients, respectively. All of the PR cases had T4 tumors and the patients with tumors smaller than T3 and without lymph node metastasis achieved CR. All patients completed radiotherapy without acute severe complications. Six patients have remained alive for more than 10 months and radiation induced late complications such as bladder or intestinal insufficiency have not been observed thus far. (author)

    Purpose: Stereotactic body radiation therapy (SBRT) allows stereotactic irradiation of thoracic tumors. It may have a real impact on patients who may not otherwise qualify for breast-conserving surgery. We conducted a phase 1 trial that tested 5 dose levels of SBRT concomitant with neoadjuvant chemotherapy (NACT) before to surgery. The purpose of the current dose escalation study was to determine the maximum tolerable dose of SBRT in the treatment of breast cancer. Methods and Materials: To define toxicity, we performed dermatologic examinations that included clinical examinations by 2 separate physicians and technical evaluations using colorimetry, dermoscopy, and skin ultrasonography. Dermatologic examinations were performed before NACT, 36 and 56 days after the beginning of NACT, and before surgery. Surgery was performed 4 to 8 weeks after the last chemotherapy session. Efficacy, the primary endpoint, was determined by the pathologic complete response (pCR) rate. Results: Maximum tolerable dose was not reached. Only 1 case of dose-limiting toxicity was reported (grade 3 dermatologic toxicity), and SBRT was overall well tolerated. The pCR rate was 36%, with none being observed at the first 2 dose levels, and the highest rate being obtained at dose level 3 (25.5 Gy delivered in 3 fractions). Furthermore, the breast-conserving surgery rate was up to 92% compared with an 8% total mastectomy rate. No surgical complications were reported. Conclusions: This study demonstrates that SBRT can be safely combined with NACT. Regarding the efficacy endpoints, this trial showed promising results in terms of pCR rate (36%) and breast-conserving rate (92%). The findings provide a strong rationale for extending the study into a phase 2 trial. In view of the absence of correlation between dose and pCR, and given that the data from dose level 3 met the statistical requirements, a dose of 25.5 Gy in 3 fractions should be used for the phase 2 trial.

    Objective: To evaluate the efficacy of adjuvant chemotherapy after radical surgery for non-small cell lung cancer (NSCLC). Methods: Seventy patients with NSCLC (stage Ⅰ-Ⅲ) undergone radical surgery were randomized into two groups: 35 patients received adjuvant chemotherapy with cyclophosphamide (CTX)300 mg/m2, vincristine (VCR) 1.4% mg/m2, adriamycin (ADM) 50 mg/m2, lomustine (CCNU) 50 mg/m2 d1,cisplatin (DDP) 20 mg/m2, d1-5, for 4 cycles, and followed by oral Ftorafur (FT-207) 600-900 mg/d for 1year (adjuvant chemotherapy group). The other 35patients received surgical treatment only (surgery group). Results: The overall 5-year survival rate was 48.6% in the adjuvant chemotherapy group, and 31.4%in the surgery group, respectively. The difference between the two groups was not statistically significant (P>0.05). The 5-year survival rate of patients in stage Ⅲwas 44.0% and 20.8% received surgery with and without adjuvant chemotherapy, respectively. The difference between the two groups was statistically significant (P<0.025). The 5-year survival rate of patients in stage Ⅰ-Ⅱ in the two groups was 60.0% and 54.5%, respectively (P>0.75). Conclusion: Postoperative adjuvant chemotherapy in NSCLC can improve survival, for those patients in stage Ⅲ, it suggests significantly 5-year survival rate in the adjuvant chemotherapy group was higher than that in the surgery alone group.

    Five years overall survival in osteosarcoma patients is around 70%, although in patients with metastatic disease it is only 10-30%. The objective of this study was to analyze overall survival and prognostic factors in a group of patients with metastatic osteosarcoma treated with surgical removal of the lung metastases. A retrospective review from our oncology data base revealed 38 patients treated between 1992 and 2006. The mean age at diagnosis was 18 ± 9.4 years (3-45) and mean follow-up was 57 ± 53.8 months (12-231). All patients were treated with chemotherapy and oncologic resection of the primary tumor and surgical removal of the lung metastases. We analyzed overall survival and prognostic factors: age, gender, site, time of metastasis, local recurrences, number of lung metastasis and chemotherapy response (necrosis). Overall survival of the entire series was 29% at 5 years (CI 95%: 14.5-43.5) and 26% at 10 years (CI 95%: 12-40). Significant difference in 5 year overall survival was found between good and bad responders to chemotherapy, 53% (IC 95%: 28-78) vs. 8% (IC 95%: 0-20) (p = 0.0008). No statistically significant relationship between other prognostic factors analyzed was observed. Five and ten years overall survival rates in osteosarcoma patients with lung metastasis treated with chemotherapy and surgically resection is poor. Patients with good response to chemotherapy have better prognosis.

    This is a retrospective study of patients treated for cervix cancer staged IB2, IIA or IIB with bulky tumor (> 4cm). Treatment was concurrent radiotherapy (45Gy with 1,8Gy daily fraction) and chemotherapy (5 cycles of Platinum 40mg/m2/week). All patients underwent Brachytherapy (15Gy on the reference isodose according to Paris system) followed by surgery (radical abdominal hysterectomy and bilateral pelvic lymphadenectomy: Piver 3) Between October 1999 and December 2002, forty five patients were treated in this protocol. Median age was 46 years (21- 68). Histology was squamous cell carcinoma in 93% and glandular carcinoma in 7%. Average external radiation dose was 44Gy (20-50). Ninety three percent of patients had at least 3 cycles of chemotherapy and 46,5% received the planned 5 cycles. On the operative specimens, there was 62,5% complete response and only 7 pelvic node involvement (17,5%). Four postoperative complications were noted (one vascular injury, one urinary fistula, one phlebitis and one lymph collection). Preoperative combined radiotherapy and chemotherapy in the early bulky stages of uterine cervix cancer is well tolerated and "gives" a high rate of sterilisation. There was no increase in surgical morbidity.

    Peritoneal carcinomatosis in gastric cancer is associated with a dismal prognosis. Systemic chemotherapy is not effective because of the existence of a blood-peritoneal barrier. Cytoreductive surgery and intraperitoneal chemotherapy can improve survival and quality of life in selected patients. Patient selection for this multimodal approach is one of the most critical issues, and calls for interdisciplinary evaluation by radiologists, medical and surgical oncologists, and anaesthetists. This article sets forth criteria for selection of gastric cancer patients suffering from peritoneal carcinomatosis.

    Purpose: To report the early outcomes for very young children with medulloblastoma or supratentorial primitive neuroectodermal tumor (SPNET) treated with upfront chemotherapy followed by 3-dimensional proton radiation therapy (3D-CPT). Methods and Materials: All patients aged <60 months with medulloblastoma or SPNET treated with chemotherapy before 3D-CPT from 2002 to 2010 at our institution were included. All patients underwent maximal surgical resection, chemotherapy, and adjuvant 3D-CPT with either craniospinal irradiation followed by involved-field radiation therapy or involved-field radiation therapy alone. Results: Fifteen patients (median age at diagnosis, 35 months) were treated with high-dose chemotherapy and 3D-CPT. Twelve of 15 patients had medulloblastoma; 3 of 15 patients had SPNET. Median time from surgery to initiation of radiation was 219 days. Median craniospinal irradiation dose was 21.6 Gy (relative biologic effectiveness); median boost dose was 54.0 Gy (relative biologic effectiveness). At a median of 39 months from completion of radiation, 1 of 15 was deceased after a local failure, 1 of 15 had died from a non-disease-related cause, and the remaining 13 of 15 patients were alive without evidence of disease recurrence. Ototoxicity and endocrinopathies were the most common long-term toxicities, with 2 of 15 children requiring hearing aids and 3 of 15 requiring exogenous hormones. Conclusions: Proton radiation after chemotherapy resulted in good disease outcomes for a small cohort of very young patients with medulloblastoma and SPNET. Longer follow-up and larger numbers of patients are needed to assess long-term outcomes and late toxicity.

    Purpose: To examine clinical outcomes and relapse patterns in locally advanced vulvar carcinoma treated using preoperative chemotherapy and intensity modulated radiation therapy (IMRT). Methods and Materials: Forty-two patients with stage I-IV{sub A} (stage I, n=3; stage II, n=13; stage III, n=23; stage IV{sub A}, n=3) vulvar cancer were treated with chemotherapy and IMRT via a modified Gynecological Oncology Group schema using 5-fluorouracil and cisplatin with twice-daily IMRT during the first and last weeks of treatment or weekly cisplatin with daily radiation therapy. Median dose of radiation was 46.4 Gy. Results: Thirty-three patients (78.6%) had surgery for resection of vulva; 13 of these patients also had inguinal lymph node dissection. Complete pathologic response was seen in 48.5% (n=16) of these patients. Of these, 15 had no recurrence at a median time of 26.5 months. Of the 17 patients with partial pathological response, 8 (47.1%) developed recurrence in the vulvar surgical site within a median of 8 (range, 5-34) months. No patient had grade ≥3 chronic gastrointestinal/genitourinary toxicity. Of those having surgery, 8 (24.2%) developed wound infections requiring debridement. Conclusions: Preoperative chemotherapy/IMRT was well tolerated, with good pathologic response and clinical outcome. The most common pattern of recurrence was local in patients with partial response, and strategies to increase pathologic response rate with increasing dose or adding different chemotherapy need to be explored to help further improve outcomes.

    Neoadjuvant chemotherapy (NAC), the systematic chemotherapy given to patients with locally advanced and inoperable breast caner, has been proven to be of great clinical values. Many scientific reports confirmed NAC could effectively eliminate sub-clinical disseminated lesions of tumor, and improve long-term and disease-free survival rate of patients with locally advanced breast cancer (LABC); however, up to now, LABC is still a serious clinical issue given improved screening and early diagnosis. This study, with main focus on inoperable LABC, investigated the values of NAC in converting inoperable LABC into operable status and assessed the prognosis. Sixty-one patients with inoperable LABC were initially treated with neoadjuvant chemotherapy; their local conditions were improved to operable status. Radical surgery was exerted on 49 patients. Original chemotherapy was performed after surgery, followed by local radiotherapy. And endocrine therapy was optional according to the hormone receptor status. The quality of life for most patients with skin diabrosis was obviously improved because their local conditions were under control. For all recruited cases, the survival duration and life quality were significantly improved in patients who finished both NAC and surgery compared to those who did not. Further more, this study demonstrates improved prognostic consequences.

    In recent years, lymphadenitis caused by atypical mycobacteria (also called nontuberculous mycobacteria [NTMB] or, more recently, environmental) have played a significant role in the differential diagnosis of adenitis in non-immunocompromised children. To describe the clinical and pathological findings in childhood NTMB adenitis and study the possible usefulness of antimicrobial therapy in addition to surgery. We present eight cases of neck lymphadenitis occurring over a 5-year period. All of the children received combined chemotherapy, and six also underwent surgery. Of the two remaining patients, the parents of one child refused surgery and a watchful approach was adopted in the other. Complete clinical recovery was achieved in all patients except one who did not undergo surgery. Prolonged administration of two antibiotics (of which one must be clarithromycin) in addition to surgery was well-tolerated and could be useful in patients with NTMB neck lymphadenitis.

    Purpose: A phase 2 study was completed by the Korean Gynecologic Oncologic Group to evaluate the efficacy and toxicity of concurrent chemoradiation with weekly paclitaxel in patients with high-risk endometrial cancer. Methods and Materials: Pathologic requirements included endometrial endometrioid adenocarcinoma stages III and IV. Radiation therapy consisted of a total dose of 4500 to 5040 cGy in 5 fractions per week for 6 weeks. Paclitaxel 60 mg/m{sup 2} was administered once weekly for 5 weeks during radiation therapy. Results: Fifty-seven patients were enrolled between January 2006 and March 2008. The median follow-up time was 60.0 months (95% confidence interval [CI], 51.0-58.2). All grade 3/4 toxicities were hematologic and usually self-limited. There was no life-threatening toxicity. The cumulative incidence of intrapelvic recurrence sites was 1.9% (1/52), and the cumulative incidence of extrapelvic recurrence sites was 34.6% (18/52). The estimated 5-year disease-free and overall survival rates were 63.5% (95% CI, 50.4-76.5) and 82.7% (95% CI, 72.4-92.9), respectively. Conclusions: Concurrent chemoradiation with weekly paclitaxel is well tolerated and seems to be effective for high-risk endometrioid endometrial cancers. This approach appears reasonable to be tested for efficacy in a prospective, randomized controlled study.

  4. Liver Injury Induced by Anticancer Chemotherapy and Radiation Therapy

    2013-01-01

    Full Text Available Cytotoxic chemotherapy prolongs survival of patients with advanced and metastatic tumors. This is, however, a double-edged sword with many adverse effects. Since the liver has a rich blood supply and plays an active role in the metabolism of medications, it is not surprising that there can be hepatic injury related to chemotherapy. In addition, radioembolization may affect the parenchyma of normal and cirrhotic livers. We review chemotherapy-associated liver injury in patients with colorectal liver metastases, including downsizing chemotherapy and neoadjuvant chemotherapy. We discuss the mechanism of the hepatic injury, secondary to reactive oxygen species, and the spectrum of hepatic injury including, steatosis, steatohepatitis, hepatic sinusoidal injury and highlight the pharmacogenomics of such liver insults. Methods for reducing and treating the hepatotoxicity are discussed for specific agents including tamxifen and the newly introduced targeted antibodies.

  5. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy: a review of factors contributing to morbidity and mortality

    2016-01-01

    Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is associated with prolonged survival for appropriately selected patients with peritoneal dissemination of abdominal malignancies. CRS and HIPEC has been criticized for perceived high rates of morbidity and mortality. Morbidity and mortality rates of CRS and HIPEC, however, do not appear dissimilar to those of other large abdominal surgeries, particularly when relevant patient and operative factors are accounted for. The risk of morbidity and mortality following this surgery for a given individual can be predicted in part by a variety of patient and operative factors. While strong data are lacking, the limited data that exists on the matter suggests that the independent contribution of the heated intraperitoneal chemotherapy to CRS and HIPEC morbidity is relatively small. A more thorough understanding of the patient and operative factors associated with CRS and HIPEC morbidity and mortality, as well as the specific complications related to the intraperitoneal chemotherapy, can better inform clinicians in multidisciplinary teams and patients alike in the decision-making for this surgery.

    One of the very common side effects of Radiation/Chemotherapy especially of the head and neck malignancies is mucositis. Cancer therapy or the cancer itself may cause changes in the body chemistry that results in loss of appetite, pain, nausea, vomiting, diarrhea and very common mucositis which makes eating difficult. Loss of appetite is followed by an undesirable loss of weight due to insufficient amount of calories every day which can lead to loss of muscle mass and strength and other complications by causing interruptions of medical therapy, impeding effective cancer therapy. Mucositis cause decreased immunity and quality of life as well as poor tolerance to surgery and altered efficacy of Chemotherapy and Radiotherapy. The present study is designed with the objective to minimize the radiation induced mucositis, skin reaction, xerostomia, change in voice etc. with an Ayurvedic preparation Yashtimadhu Ghrita (processed ghee). Total 75 patients were randomly divided into four groups and drugs were administered: Group A with local application of Yashtimadhu powder and honey in the oral cavity for few minutes prior to radiotherapy along with oral intake of Yashtimadhu Ghrita; Group B with only local application of the Yashtimadhu powder and honey in the oral cavity; Group C patients administered with only local application of honey in the oral cavity; Group D on conventional modern medication controlled group. All these patients under four groups had received Radiotherapy and Chemotherapy for maximum duration of 7 weeks. Mucositis and Skin reactions were observed in 100% of patients with varying degree. The intensity of Radiation and Chemotherapy induced mucositis was reduced to a great extent by the trial drug. Yashtimadhu (Glycyrrhiza glabra) can be used effectively in prevention and treatment of oral mucositis post radiation and chemotheraphy in patients of cancer, especially of the head and neck region. It proves beneficial in two ways: (i) there were no

    Full Text Available The development of breast implant associated anaplastic large cell lymphoma (ALCL is a rare phenomenon. A typical presentation is an effusion associated with a breast implant. Less commonly, disease can become more advanced locoregionally or distantly. The optimal treatment schema is a topic of debate: localized ALCL can potentially be cured with implant removal alone, while other cases in the literature, including those that are more advanced, have been treated with varying combinations of surgery, chemotherapy, and external beam radiotherapy. This is a case report of breast implant ALCL with pathologically proven lymph node involvement, the fifth such patient reported. Our patient experienced a favorable outcome with radiation therapy and chemotherapy.

    Cytoreductive surgery (CRS) followed by hyperthermic intraperitoneal chemotherapy (HIPEC) is a radical but effective treatment option for select peritoneal malignancies. We sought to determine our early experience with this method for peritoneal carcinomatosis secondary to mucinous adenocarcinomas of appendiceal origin. As such, we performed a retrospective clinical study of 30 consecutive patients undergoing CRS with planned HIPEC at the Princess Alexandra Hospital, between June 2009 to Dece...

    Purpose: To estimate the radiation equivalent of the chemotherapy contribution to observed complete response rates in published results of 1-phase radio-chemotherapy of muscle-invasive bladder cancer. Methods and Materials: A standard logistic dose–response curve was fitted to data from radiation therapy-alone trials and then used as the platform from which to quantify the chemotherapy contribution in 1-phase radio-chemotherapy trials. Two possible mechanisms of chemotherapy effect were assumed (1) a fixed radiation-independent contribution to local control; or (2) a fixed degree of chemotherapy-induced radiosensitization. A combination of both mechanisms was also considered. Results: The respective best-fit values of the independent chemotherapy-induced complete response (CCR) and radiosensitization (s) coefficients were 0.40 (95% confidence interval −0.07 to 0.87) and 1.30 (95% confidence interval 0.86-1.70). Independent chemotherapy effect was slightly favored by the analysis, and the derived CCR value was consistent with reports of pathologic complete response rates seen in neoadjuvant chemotherapy-alone treatments of muscle-invasive bladder cancer. The radiation equivalent of the CCR was 36.3 Gy. Conclusion: Although the data points in the analyzed radio-chemotherapy studies are widely dispersed (largely on account of the diverse range of chemotherapy schedules used), it is nonetheless possible to fit plausible-looking response curves. The methodology used here is based on a standard technique for analyzing dose-response in radiation therapy-alone studies and is capable of application to other mixed-modality treatment combinations involving radiation therapy.

    The optimal treatment of advanced maxillary sinus cancer has been challenging for several decades. Intra-arterial chemotherapy (IAC) for head and neck cancer has been controversial. We have analyzed the long-term outcome of neoadjuvant IAC followed by radiation therapy (RT) and surgery. Twenty-seven patients with advanced maxillary sinus cancer were treated between 1989 and 2002. Five-fluorouracil (5-FU, 500 mg/m2) was infused intra-arterially, and followed by RT (total 50.4 Gy/28 fractions). A planned surgery was performed 3 to 4 weeks after completion of IAC and RT. At a median follow-up of 77 months (range, 12 to 169 months), the 5-year rates of overall survival in all patients were 63%. The 5-year rates of overall survival of stage T3/T4 patients were 70.0% and 58.8%, respectively. Seven of fourteen patients with disease recurrence had a local recurrence alone. The 5-year actuarial local control rates in patients with stage T3/T4, and in all patients were 20.0%, 32.3%, and 27.4%, respectively. Overall response rate after the completion of IAC and RT was 70.3%. During the follow-up, seven patients (25.9%) showed mild to moderate late complications. The tumor extent (i.e., the involvement of either orbit and/or base of skull) appeared to be related with local recurrence. Neoadjuvant IAC with 5-FU followed by RT and surgery may be effective to improve local tumor control in the patients with advanced maxillary sinus cancer. However, local failure was still the major cause of death. Further investigations are required to determine the optimal treatment schedule, radiotherapy techniques and chemotherapy regimens.

    .105). Conclusions:Patients with MIBC who overexpress Ki-67 and with negative hormonal receptors have relatively substantial risk of relapse within the first five years after surgery. However, adjuvant chemotherapy can only improve the outcomes of ER(-)/PR(-) patients, but not those who overexpress Ki-67. Further studies with prolonged follow-up of large cohorts are recommended to assess the prognostic significance and treatment of this lesion.

    The primary results of our phase II randomized trial suggested that compared with conventional preoperative chemoradiation (CRT), the addition of chemotherapy (CT) before CRT and surgery allows most patients receive their planned treatment with a better toxicity profile without compromising the pathological complete response and complete resection rates. We now report the 5-year outcomes. Patients with distal or middle third, T3-T4 and/or N+ rectal adenocarcinoma selected by magnetic resonance imaging, were randomly assigned to arm A-preoperative CRT followed by surgery and four cycles of postoperative adjuvant capecitabine and oxaliplatin (CAPOX)-or arm B-four cycles of CAPOX followed by CRT and surgery. The following 5-year actuarial outcomes were assessed: the cumulative incidence of local relapse (LR) and distant metastases (DM), disease-free (DFS) and overall survival (OS). A total of 108 eligible patients were randomly assigned to arm A (n = 52) or arm B (n = 56). With a median follow-up of 69.5 months, 5-year DFS was 64% in arm A and 62% in arm B (P = 0.85) and 5-year OS was 78% in arm A and 75% in arm B (P = 0.64). The 5-year cumulative incidence of LR was 2% and 5% (P = 0.61) and 5-year cumulative incidence of DM was 21% and 23%; (P = 0.79) in arms A and B, respectively. Both treatment approaches yield similar outcomes. Given the lower acute toxicity and improved compliance with induction CT compared with adjuvant CT, integrating effective systemic therapy before CRT and surgery is a promising strategy and should be examined in phase III trials. © The Author 2015.

    In recent years, the incidence of therapy-related myelodysplastic syndrome (t-MDS) and therapy-related acute myeloid leukemia (t-AML) that occur during chemotherapy for ovarian cancer has increased. While alkylating agents and topoisomerase II inhibitors are particularly mutagenic and have strong leukemogenic potential, paclitaxel and combination chemotherapy/radiation therapy also appear to induce t-MDS. The present authors report a case of t-MDS that developed during chemotherapy and radiation therapy for ovarian cancer. The patient was a 75-year-old woman who received six courses of cyclophosphamide/doxorubicin/cisplatin (CAP) therapy after initial surgery for Stage IIIc grade ovarian cancer in 1995. Beginning in February 2005, the patient experienced multiple recurrences due to sternal metastasis. Chemotherapy, including paclitaxel and carboplatin (TC), was administered intermittently and was combined with radiation therapy to a sternal metastatic lesion. Pancytopenia was observed in December 2008, and she was diagnosed with t-MDS (WHO subtype, refractory cytopenias with multilineage dysplasia [RCMD]): the time from first chemotherapy to t-MDS onset was 106 months. Without evidence of blast crisis, the recurrent lesions continued to grow and caused multiple cerebral infarctions, from which she eventually died. The cumulative doses of paclitaxel and carboplatin administered to this patient were 1,968 mg and 6,480 mg, respectively.

  16. Current status and future strategies of cytoreductive surgery plus intraperitoneal hyperthermic chemotherapy for peritoneal carcinomatosis

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    This article is to offer a concise review on the use of cytoreductive surgery (CRS) plus intraperitoneal hyperthermic chemotherapy (IPHC) for the treatment of peritoneal carcinomatosis (PC). Traditionally, PC was treated with systemic chemotherapy alone with very poor response and a median survival of less than 6 mo. With the establishment of several phase studies, a new trend has been developed toward the use of CRS plus IPHC as a standard method for treating selected patients with PC, in whom sufficient cytoreduction could be achieved. In spite of the need for more high quality phase studies, there is now a consensus among many surgical oncology experts throughout the world about the use of this new treatment strategy as standard care for colorectal cancer patients with PC. This review summarizes the current status and possible progress in future.

    This is a retrospective study to evaluate the response rate, acute toxicity, and survival rate of a combined chemotherapy and radiation therapy in limited disease small cell lung cancer. Forty six patients with limited disease small-cell lung cancer who underwent combined chemotherapy and radiation therapy between October 1994 and April 1998 were evaluated. Six cycles of chemotherapy were planned either using a VIP regimen (etoposide, ifosfamide, and cis-platin) or a EP regimen (etoposide and cis-platin). Thoracic radiation therapy was planned to deliver 44 Gy using 10MV X-ray, starting concurrently with chemotherapy. Response was evaluated 4 weeks after the completion of the planned chemotherapy and radiation therapy, and the prophylactic cranial irradiation was planned only for the patients with complete responses. Acute toxicity was evaluated using the SWOG toxicity criteria, and the overall survival and disease-free survival were calculated using the Kaplan-Meier Method. The median follow-up period was 16 months (range:2 to 41 months). Complete response was achieved in 30 (65%) patients, of which 22 patients received prophylactic cranial irradiations. Acute toxicities over grade III were granulocytopenia in 23 (50%), anemia in 17 (37%), thrombo-cytopenia in nine (20%), alopecia in nine (20%), nausea/vomiting in five (11%), and peripheral neuropathy in one (2%). Chemotherapy was delayed in one patient, and the chemotherapy doses were reduced in 58 (24%) out of the total 246 cycles. No radiation esophagitis over grade III was observed, while interruption during radiation therapy for a mean of 8.3 days occurred in 21 patients. The local recurrences were observed in 8 patients and local progressions were in 6 patients, and the distant metastases in 17 patients. Among these, four patients had both the local relapse and the distant metastasis. Brain was the most common metastatic site (10 patients), followed by the liver as the next common site (4 patients).

    Blood platelets from patients with cancer (before or after the surgery) exhibit a variety of qualitative abnormalities. Different anti-cancer drugs may also induce the oxidative/nitrative stress in blood platelets and change their hemostatic properties. The aim of our study was to explain the effect of superoxide anion radicals ([Formula: see text]) production on hemostatic properties of blood platelets (activated by a strong physiological agonist - thrombin) from breast cancer patients before the surgery, after the surgery, and after various phases (I-IV) of chemotherapy (doxorubicin and cyclophosphamide). Patients were hospitalized in the Department of Oncological Surgery and at the Department of Chemotherapy, Medical University of Lodz, Poland. We measured the platelet aggregation as the marker of hemostatic activity of blood platelets. We observed an increase of [Formula: see text] in thrombin-activated blood platelets from patients with breast cancer (before or after the surgery and after various phases of the chemotherapy) compared to the healthy group. Our other experiments demonstrated that aggregation (induced by thrombin) of blood platelets from patients with breast cancer before the surgery, after the surgery, and after various phases of the chemotherapy differs from aggregation of platelets obtained from healthy volunteers. Moreover, our results showed the correlation between the [Formula: see text] generation and changes of platelet aggregation in breast cancer patients before the surgery, after the surgery, and after the chemotherapy (I and IV phases). Considering the data presented in this study, we suggest that the production of [Formula: see text] in blood platelets (activated by thrombin) obtained from breast cancer patients may induce the changes of platelet aggregation, which may contribute in thrombosis in these patients.

    For children with stage II testicular malignant germ cell tumors (MGCT), the survival is good with surgery and adjuvant chemotherapy. However, there is limited data on surgical results for cases in which there was no imaging or pathologic evidence of residual tumor, but in which serum tumor markers either increased or failed to normalize after an appropriate period of half-life time post-surgery. To determine the use of chemotherapy for children with stage II germ cel tumors, we analyzed the outcomes (relapse rate and overall survival) of patients who were treated at the Sun Yat-sen University Cancer Center between January 1990 and May 2013. Twenty-four pediatric patients with a median age of 20 months (range, 4 months to 17 years) were enrol ed in this study. In 20 cases (83.3%), the tumors had yolk sac histology. For definitive treatment, 21 patients underwent surgery alone, and 3 patients received surgery and adjuvant chemotherapy. No relapse was observed in the 3 patients who received adjuvant chemotherapy, whereas relapse occurred in 16 of the 21 patients (76.2%) treated with surgery alone. There were a total of 2 deaths. Treatment was stopped for 1 patient, who died 3 months later due to the tumor. The other patient achieved complete response after salvage treatment, but developed lung and pelvic metastases 7 months later and died of the tumor after stopping treatment. For children treated with surgery alone and surgery combined with adjuvant chemotherapy, the 3-year event-free survival rates were 23.8% and 100%, respectively (P=0.042), and the 3-year overal survival rates were 90.5%and 100%, respectively (P=0.588). These results suggest that adjuvant chemotherapy can help to reduce the recurrence rate and increase the survival rate for patients with stage II germ cel tumors.

    2014-01-01

    Full Text Available Introduction. Cytoreductive surgery (CS with hyperthermic intraperitoneal chemotherapy (HIPEC is a new approach for peritoneal carcinomatosis. However, high rates of complications are associated with CS and HIPEC due to treatment complexity; that is why some patients need stabilization and surveillance for complications in the intensive care unit. Objective. This study analyzed that ICU stay is necessary after HIPEC. Methods. 39 patients with peritoneal carcinomatosis were treated according to strict selection criteria with CS and HIPEC, with closed technique, and the chemotherapy administered were cisplatin 25 mg/m2/L and mitomycin C 3.3 mg/m2/L for 90-minutes at 40.5°C. Results. 26 (67% of the 39 patients were transferred to the ICU. Major postoperative complications were seen in 14/26 patients (53%. The mean time on surgical procedures was 7.06 hours (range 5−9 hours. The mean blood loss was 939 ml (range 100–3700 ml. The mean time stay in the ICU was 2.7 days. Conclusion. CS with HIPEC for the treatment of PC results in low mortality and high morbidity. Therefore, ICU stay directly following HIPEC should not be standardized, but should preferably be based on the extent or resections performed and individual patient characteristics and risk factors. Late complications were comparable to those reported after large abdominal surgery without HIPEC.

    Diffuse malignant peritoneal mesothelioma is a rare and lethal disease. Locoregional treatments combining cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (HIPEC) seem to improve prognosis. Cytoreductive surgery and HIPEC was performed in 22 patients at the Centre Hospitalier-Lyon Sud between 1989 and 2006. A retrospective analysis of survival was carried out to assess clinical and histological prognostic factors. Nineteen patients with diffuse malignant peritoneal mesothelioma were included (16 epithelial, 3 biphasic and 3 multicystic forms). Sixteen patients presented stage 3 or 4 peritoneal mesothelioma according to the Gilly classification. Optimal cytoreductive surgery was performed for 11 patients (complete macroscopic resection or residual tumor nodules less than 2.5mm). No post-operative deaths occurred but 9 patients (47%) presented grade III or IV post-operative complications. The overall median survival was 36.9 months; completeness of cytoreduction was the only significant prognostic factor. Cytoreductive surgery combined with HIPEC may improve the length of survival for patients with diffuse malignant peritoneal mesothelioma; such patients should be treated in specialized centers.

    To evaluate the long-term results after breast-conserving surgery and radiation therapy in early breast cancer in terms of failure, survival, and cosmesis. One hundred fifty-four patients with stage I and II breast cancer were treated with conservative surgery plus radiotherapy between January 1992 and December 2002 at the Keimyung University Dongsan Medical Center. According to TNM stage, 93 patients were stage I, 50 were IIa, and 11 were IIb. The affected breasts were irradiated with 6 MV photons to 50.4 Gy in 28 fractions over 5.5 weeks with a boost irradiation dose of 10{approx}16 Gy to the excision site. Chemotherapy was administered in 75 patients and hormonal therapy in 92 patients with tamoxifen. Follow-up periods were 13{approx}179 months, with a median of 92.5 months. The 5- and 10-year overall survival rates were 97.3% and 94.5%, respectively. The 5- and 10-year disease-free survival (5YDFS and 10YDFS, respectively) rates were 92.5% and 88.9%, respectively; the ultimate 5YDFS and 10YDFS rates after salvage treatment were 93.9% and 90.2%, respectively. Based on multivariate analysis, only the interval between surgery and radiation therapy ({<=}6 weeks vs. >6 weeks, p=0.017) was a statistically significant prognostic factor for DFS. The major type of treatment failure was distant failure (78.5%) and the most common distant metastatic site was the lungs. The cosmetic results were good-to-excellent in 96 patients (80.7%). Conservative surgery and radiation for early stage invasive breast cancer yielded excellent survival and cosmetic results. Radiation therapy should be started as soon as possible after breast-conserving surgery in patients with early breast cancer, ideally within 6 weeks.

    Background There is little information on the impact of intra-operative systemic chemotherapy on gastric cancer.The aim of this study was to identify prognostic factors in patients with locally advanced gastric cancer and undergoing curative resection,with a focus on evaluating survival benefits and tolerance of intra-operative systemic chemotherapy.Methods We retrospectively analyzed clinicopathological data for 264 consecutive patients who underwent curative resection for gastric cancer at Peking Union Medical College Hospital from January 2002 to January 2007.Survival curves were plotted using the Kaplan-Meier method and compared using log-rank tests.Univariate and multivariate analyses were performed with the Cox proportional hazard model.Results Patients who received intra-operative systemic chemotherapy had higher 5-year overall survival and 5-year disease-free survival rates (P=0.019 and 0.010,respectively) than patients who did not receive intra-operative systemic chemotherapy.In the subgroup analysis,systemic intra-operative chemotherapy benefited the 5-year overall survival and disease-free survival rates for patients with cancer of stage pTNM ⅠB-ⅢB,but not stage pTNM ⅢC.Patients who received intra-operative systemic chemotherapy in combination with post-operative chemotherapy had higher 5-year overall survival and 5-year disease-free survival rates (P=0.046 and 0.021,respectively) than patients who only received postoperative chemotherapy.However,the difference in these rates between patients who received only intra-operative systemic chemotherapy and patients who only received curative surgery was not statistically significant (P=0.150 and 0.170,respectively).Multivariate analyses showed that intra-operative systemic chemotherapy was a favorable prognostic factor for the overall survival and disease-free survival rates (P =0.048 and 0.023,respectively).No grade 4 toxicities related to intra-operative systemic chemotherapy were recorded within the

    Full Text Available For pregnant patients with cervical cancer, treatment recommendations are individualized and dependent on the stage of the disease, gestational age at the time of diagnosis, and the patient's desire as to the cosntinuation of the pregnancy. The aim of this study is to describe the outcome of neoadjuvant chemotherapy with radical surgery and pelvic lymphadenectomy in a woman with cervical cancer who wished to maintain her pregnancy. This is a report of a 26-week pregnant woman with locally advanced cervical cancer stage Ib2 (FIGO who was successfully treated with neoadjuvant chemotherapy Paclitaxel plus platinum, followed by C/S and radical surgery. Her neonate was healthy and had no abnormalities. This case was the first cervical cancer during pregnancy that was treated using this method at the tumor clinic, Mashhad University of Medical Sciences, Iran. Neoadjuvant chemotherapy is an effort to allow time for the fetal to reach viability by preventing the progression of the disease.

    Dosage and frequency of treatment schedules are important for successful chemotherapy. However, in this work we argue that cell-kill response and tumoral growth should not be seen as separate and therefore are essential in a mathematical cancer model. This paper presents a mathematical model for sequencing of cancer chemotherapy and surgery. Our purpose is to investigate treatments for large human tumours considering a suitable cell-kill dynamics. We use some biological and pharmacological data in a numerical approach, where drug administration occurs in cycles (periodic infusion) and surgery is performed instantaneously. Moreover, we also present an analysis of stability for a chemotherapeutic model with continuous drug administration. According to Norton and Simon [22], our results indicate that chemotherapy is less efficient in treating tumours that have reached a plateau level of growing and that a combination with surgical treatment can provide better outcomes.

    Body weight loss is a common outcome in patients with gastric cancer who have undergone gastrectomy. However, the rate of body weight loss after surgery is unknown. In this retrospective study, we selected patients who underwent radical gastrectomy for gastric cancer and were diagnosed with Stage II or III disease. Further, we compared the body weight loss after surgery between patients in the surgery alone group and the S-1 adjuvant chemotherapy group. We evaluated 163 patients, of which 81 underwent only surgery, and 82 underwent surgery followed up with S-1 adjuvant chemotherapy. The body weight loss rate at 1, 3, and 6 months in the surgery alone group were 93.1%, 92.9%, and 94.9%, while those in the S-1 adjuvant group were 92.9%, 90.4%,and 91.9%, which was a significant difference. Body weight loss after gastrectomy was higher in the S-1 adjuvant group than in the surgery alone group. Further, nutritional support is required for these patients to maintain body weight after surgery.

    Microporosities play important biologic and mechanical roles on health. One of the side effects caused by some chemotherapy drugs is the induction of amenorrhea, temporary or not, in premenopausal women, with a consequent decrease in estrogen production, which can lead to cortical bone changes. In the present work, the femur diaphysis of rats treated with chemotherapy drugs were evaluated by 3D morphometric parameters using synchrotron radiation microtomography. Control animals were also evaluated for comparison. The 3D tomographic images were obtained at the SYRMEP (SYnchrotron Radiation for MEdical Physics) beamline at the ELETTRA Synchrotron Laboratory in Trieste, Italy. Results showed significant differences in morphometric parameters measured from the 3D images of femur diaphysis of rats.

    Radiation recall dermatitis (RRD) is an acute skin toxicity caused by different anticancer or antibiotic drugs within a former completely healed irradiation field. Predictive factors for RRD are not known and its mechanisms are not completely understood. A case of RRD induced by docetaxel and successfully treated by an antioxidant ointment (Mapisal {sup registered}) is presented here. Such an ointment might be useful not only in RRD therapy, but also in the treatment of high-grade dermatitis induced by radiotherapy and thus may contribute to the improvement of patients' quality of life and to the scheduled completion of cancer therapies. (orig.) [German] Die Strahlen-Recall-Dermatitis (RRD) ist eine akute Hauttoxizitaet, die durch verschiedene Chemotherapeutika oder Antibiotika innerhalb eines frueheren, komplett abgeheilten Bestrahlungsfelds hervorgerufen wird. Praediktive Faktoren fuer die RRD sind nicht bekannt und ihr Mechanismus ist nicht vollstaendig geklaert. Es wird ein Fallbericht einer durch Docetaxel induzierten RRD dargestellt, die erfolgreich mit einer antioxidativen Salbe (Mapisal {sup registered}) behandelt wurde. Solche Salben koennten nicht nur zur Therapie der RRD, sondern auch bei der Behandlung einer akuten Dermatitis waehrend der Strahlentherapie nuetzlich sein und damit zur Verbesserung der Lebensqualitaet der Patienten und zur planmaessigen Durchfuehrung der Tumortherapie beitragen.

    Purpose: Although it is generally accepted that consolidation therapy for neuroblastoma includes irradiation of the primary site and any remaining metaiodobenzylguanidine (MIBG)-avid metastatic sites, limited information has been published regarding the efficacy of this approach. Methods and Materials: Thirty patients with high-risk neuroblastoma were treated at 1 radiation therapy (RT) department after receiving 5 cycles of induction chemotherapy and resection. All patients had at least a partial response after induction therapy, based upon international neuroblastoma response criteria. The primary sites were treated with 24 to 30 Gy whereas the MIBG-avid metastatic sites were treated with 24 Gy. RT was followed by high-dose chemotherapy with autologous stem cell rescue and 6 months of cis-retinoic acid. Results: The 5-year progression-free survival (PFS) and overall survival (OS) rates were 48% and 59%, respectively. The 5-year locoregional control at the primary site was 84%. There were no differences in locoregional control according to degree of primary surgical resection. The 5-year local control rate for metastatic sites was 74%. The 5-year PFS rates for patients with 0, 1, 2, and >3 postinduction MIBG sites were 66%, 57%, 20%, and 0% (P<.0001), respectively, whereas 5-year OS rates were 80%, 57%, 50%, and 0%, respectively (P<.0001). Conclusions: RT to the primary site and postinduction MIBG-positive metastatic sites was associated with 84% and 74% local control, respectively. The number of MIBG-avid sites present after induction chemotherapy and surgery was predictive of progression-free and overall survival.

    Full Text Available Objective. To elucidate the optimum preoperative biliary drainage method for patients with pancreatic cancer treated with neoadjuvant chemotherapy (NAC. Material and Methods. From January 2010 through December 2014, 20 patients with borderline resectable pancreatic cancer underwent preoperative biliary drainage and NAC with a plastic or metallic stent and received NAC at Hiroshima University Hospital. We retrospectively analyzed delayed NAC and complication rates due to biliary drainage, effect of stent type on perioperative factors, and hospitalization costs from diagnosis to surgery. Results. There were 11 cases of preoperative biliary drainage with plastic stents and nine metallic stents. The median age was 64.5 years; delayed NAC occurred in 9 cases with plastic stent and 1 case with metallic stent (p=0.01. The complication rates due to biliary drainage were 0% (0/9 with metallic stents and 72.7% (8/11 with plastic stents (p=0.01. Cumulative rates of complications determined with the Kaplan-Meier method on day 90 were 60% with plastic stents and 0% with metallic stents (log-rank test, p=0.012. There were no significant differences between group in perioperative factors or hospitalization costs from diagnosis to surgery. Conclusions. Metallic stent implantation may be effective for preoperative biliary drainage for pancreatic cancer treated with NAC.

    Blood lymphocyte reactivity to purified protein derivative of tuberculin (PPD) and phytohaemagglutinin (PHA) was examined in 62 patients with breast carcinoma who received postoperative adjuvant radiation therapy or cyclic chemotherapy with chlorambucil, methotrexate and 5-fluorouracil. Both treatments impaired the immunologic reactivity of blood lymphocytes as measured by PPD and PHA stimulation in vitro. Radiation therapy seemed to cause more profound and protracted suppression of the PPD response than chemotherapy.

    Full Text Available Introduction : Cancer pain is chronic pain resulting from various mechanisms related to the natural history of the disease, the course of therapy, and psychosocial factors. Aim of the research : To assess the relationship between the intensity of cancer pain in women at the final stage of chemotherapy following radical surgery of breast cancer, and the intensity of negative emotional reactions. Material and methods : The study was conducted in a population of 118 women after radical surgical treatment of breast cancer and undergoing chemotherapy at the Chemotherapy Unit of the Holycross Cancer Centre in Kielce in 2011. The research methodology consisted of a diagnostic survey and medical documentation review. Results: Strong emotional stress manifested by anxiety and depression was experienced by 48.3% and 29.7% of patients, respectively. Aggression was experienced by 15.2%. Intensification of pain was associated with the intensification of anxiety (r = 0.37; p < 0.0001, depression (r = 0.35; p < 0.01, and aggression (r = 0.30; p < 0.01. Conclusions: Adherence to the WHO-recommended analgesic ladder regimen is an effective means to treat chronic cancer pain in women in the final stage of chemotherapy following radical surgical treatment. Effective pharmacotherapy of cancer pain significantly contributes to a reduction in the intensity of negative emotional reactions, i.e. anxiety, depression, and aggression in patients undergoing chemotherapy following mastectomy. Breast cancer chemotherapy is associated with high levels of anxiety, pain, and aggression being experienced by the patients. Pain is an important determinant of the emotional state of women undergoing chemotherapy following radical cancer surgery.

    While clinical outcomes following induction chemotherapy and stereotactic body radiation therapy (SBRT) have been reported for borderline resectable pancreatic cancer (BRPC) patients, pathologic response has not previously been described. This single-institution retrospective review evaluated BRPC patients who completed induction gemcitabine-based chemotherapy followed by SBRT and surgical resection. Each surgical specimen was assigned two tumor regression grades (TRG), one using the College of American Pathologists (CAP) criteria and one using the MD Anderson Cancer Center (MDACC) criteria. Overall survival (OS) and progression free survival (PFS) were correlated to TRG score. We evaluated 36 patients with a median follow-up of 13.8 months (range, 6.1-24.8 months). The most common induction chemotherapy regimen (82%) was GTX (gemcitabine, docetaxel, capecitabine). A median SBRT dose of 35 Gy (range, 30-40 Gy) in 5 fractions was delivered to the region of vascular involvement. The margin-negative resection rate was 97.2%. Improved response according to MDACC grade trended towards superior PFS (P=061), but not OS. Any neoadjuvant treatment effect according to MDACC scoring (IIa-IV vs. I) was associated with improved OS and PFS (both P=0.019). We found no relationship between CAP score and OS or PFS. These data suggest that the increased pathologic response after induction chemotherapy and SBRT is correlated with improved survival for BRPC patients.

    The aim of this study was to review the efficacy and toxicity of radiation therapy with concurrent retrograde superselective intra-arterial chemotherapy in the treatment of gingival carcinoma. In all, 34 patients (21 men and 13 women) with squamous cell carcinoma of the gingiva underwent radiation therapy with concurrent retrograde superselective intra-arterial chemotherapy. Treatment consisted of daily external irradiation and concurrent retrograde superselective intra-arterial infusion with cisplatin and docetaxel. A median total dose of 60 Gy in 30 fractions was delivered to tumors. Of the 34 patients, 29 (85 %) achieved a complete response (CR) and 5 had residual tumors. Of the 29 patients with a CR, 2 had local recurrences and 1 had distant metastasis 1-15 months after treatment. Twenty-six of the 36 patients had survived at a median follow-up time of 36 months (range 12-79 months); 4 died of cancer and 4 died of non-cancer-related causes. At both 3 and 5 years after treatment, the overall survival rates were 79 % and the cause-specific survival rates were 85 %. Osteoradionecrosis of the mandibular bone only developed in 1 patient after treatment. Radiation therapy with concurrent retrograde superselective intra-arterial chemotherapy was effective and safe in the treatment of gingival carcinoma. This treatment may be a promising curative and organ-preserving treatment option for gingival carcinoma. (orig.)

    Cytoreductive surgery (CRS) followed by hyperthermic intraperitoneal chemotherapy (HIPEC) is a radical but effective treatment option for select peritoneal malignancies. We sought to determine our early experience with this method for peritoneal carcinomatosis secondary to mucinous adenocarcinomas of appendiceal origin. As such, we performed a retrospective clinical study of 30 consecutive patients undergoing CRS with planned HIPEC at the Princess Alexandra Hospital, between June 2009 to December 2012, with mucinous adenocarcinomas of the appendix. CRS was performed in 30 patients, 13 received HIPEC intraoperatively and 17 received early postoperative intra-peritoneal chemotherapy (EPIC) in addition. Mean age was 52.3 years and median hospital stay was 26 days (range 12–190 days). Peritoneal cancer index scores were 0–10 in 6.7% of patients, 11–20 in 20% of patients and >20 in 73.3% of patients. Complete cytoreduction was achieved overall in 21 patients. In total, 106 complications were observed in 28 patients. Ten were grade 3-A, five were grade 3-B and one grade-5 secondary to a fatal PE on day 97. In patients who received HIPEC, there was no difference in disease-free survival (P = 0.098) or overall survival (P = 0.645) between those who received EPIC versus those who did not. This study demonstrates that satisfactory outcomes with regards to morbidity and survival can be achieved with CRS and HIPEC, at a single-centre institution with growing expertise in the technique. Our results are comparable with outcomes previously described in the international literature. PMID:25594636

    The aim of this study was to investigate metabolic and textural parameters from pretreatment [{sup 18}F]FDG PET/CT scans for the prediction of neoadjuvant radiation chemotherapy response and 3-year disease-free survival (DFS) in patients with locally advanced rectal cancer (LARC). We performed a retrospective review of 74 patients diagnosed with LARC who were initially examined with [{sup 18}F]FDG PET/CT, and who underwent neoadjuvant radiation chemotherapy followed by complete resection. The standardized uptake value (mean, peak, and maximum), metabolic volume (MV), and total lesion glycolysis of rectal cancer lesions were calculated using the isocontour method with various thresholds. Using three-dimensional textural analysis, about 50 textural features were calculated for PET images. Response to neoadjuvant radiation chemotherapy, as assessed by histological tumour regression grading (TRG) after surgery and 3-year DFS, was evaluated using univariate/multivariate binary logistic regression and univariate/multivariate Cox regression analyses. MVs calculated using the thresholds mean standardized uptake value of the liver + two standard deviations (SDs), and mean standard uptake of the liver + three SDs were significantly associated with TRG. Textural parameters from histogram-based and co-occurrence analysis were significantly associated with TRG. However, multivariate analysis revealed that none of these parameters had any significance. On the other hand, MV calculated using various thresholds was significantly associated with 3-year DFS, and MV calculated using a higher threshold tended to be more strongly associated with 3-year DFS. In addition, textural parameters including kurtosis of the absolute gradient (GrKurtosis) were significantly associated with 3-year DFS. Multivariate analysis revealed that GrKurtosis could be a prognostic factor for 3-year DFS. Metabolic and textural parameters from initial [{sup 18}F]FDG PET/CT scans could be indexes to assess

    Incidence of, and baseline characteristics associated with delirium in patients after cytoreduction surgery-hyperthermic intraperitoneal chemotherapy (CRS-HIPEC), were subject of investigation. The study was conducted among a consecutive series of prospectively included patients who underwent CRS-HIPEC at the University Medical Center Groningen, Groningen, the Netherlands, between February 2006 and January 2015. A chart-based instrument for delirium during hospitalization was used to identify patients with symptoms of delirium who were not diagnosed by a psychiatrist during admission. Uni- and multivariate logistic regression analyses were performed. Data of 136 patients were included in the analysis. Median age was 60 years (range: 18-76) and 50 (37%) patients were male. During hospitalization, 38 (28%) patients were diagnosed with delirium. Factors that differed significantly between the patients with and without delirium by univariate analysis were included in multivariate analysis. Multivariate analysis showed that after adjustment for age and complications other than delirium, having three or more organs resected and the CRP serum levels were independent predictors for delirium (OR: 3.97; 95% 1.24-12.76; OR: 1.01; 95% 1-1.01, respectively). This report shows an incidence of 28% of delirium, occurring after CRS-HIPEC and suggests a role for systemic inflammation in the development of postoperative delirium. © 2017 Wiley Periodicals, Inc.

    Full Text Available Desmoplastic small round cell tumor (DSRCT is a very rare disease of children, adolescents, and young adults and involves the abdominal cavity. DSRCT has characteristic fusion gene involving EWS1 and WT1 translocation, t(11;22(p13;q12. Unlike Ewing’s sarcoma of bone, DSRCT usually presents with diffuse peritoneal implants that are prone to recur. The primary organ of origin of DSRCT is mesenchyme of the peritoneum. This makes it a very unique tumor that is difficult to treat because of the infiltrative and diffuse nature of the peritoneum. The challenge of local control is to remove dozens to hundreds of tumors studding the peritoneal cavity, and then eliminate microscopic disease. We review a sequential multimodality strategy to reduce macroscopic and microscopic disease including neoadjuvant chemotherapy, aggressive surgery including an emerging new therapy to use after surgery to treat microscopic residual disease: continuous hyperthermic peritoneal chemotherapy,

    Objectives Evidence suggests superiority of breast conserving surgery (BCS) plus radiation over mastectomy alone for treatment of early stage breast cancer. Whether the superiority of BCS plus radiation is related to the surgical approach itself or to the addition of adjuvant radiation therapy following BCS remains unclear. Materials and Methods We conducted a retrospective cohort study of women with breast cancer diagnosed from 1994–2012. Data regarding patient and tumor characteristics and treatment specifics were captured electronically. Kaplan-Meier survival analyses were performed with inverse probability of treatment weighting to reduce selection bias effects in surgical assignment. Results Data from 5335 women were included, of which two-thirds had BCS and one-third had mastectomy. Surgical decision trends changed over time with more women undergoing mastectomy in recent years. Women who underwent BCS versus mastectomy differed significantly regarding age, cancer stage/grade, adjuvant radiation, chemotherapy, and endocrine treatment. Overall survival was similar for BCS and mastectomy. When BCS plus radiation was compared to mastectomy alone, 3-, 5-, and 10-year overall survival was 96.5% vs 93.4%, 92.9% vs 88.3% and 80.9% vs 67.2%, respectively. Conclusion These analyses suggest that survival benefit is not related only to the surgery itself, but that the prognostic advantage of BCS plus radiation over mastectomy may also be related to the addition of adjuvant radiation therapy. This conclusion requires prospective confirmation in randomized trials. PMID:25487237

  13. Vascular Endothelial-Targeted Therapy Combined with Cytotoxic Chemotherapy Induces Inflammatory Intratumoral Infiltrates and Inhibits Tumor Relapses after Surgery

    Full Text Available Surgery is the most effective therapy for cancer in the United States, but disease still recurs in more than 40% of patients within 5 years after resection. Chemotherapy is given postoperatively to prevent relapses; however, this approach has had marginal success. After surgery, recurrent tumors depend on rapid neovascular proliferation to deliver nutrients and oxygen. Phosphatidylserine (PS is exposed on the vascular endothelial cells in the tumor microenvironment but is notably absent on blood vessels in normal tissues. Thus, PS is an attractive target for cancer therapy after surgery. Syngeneic mice bearing TC1 lung cancer tumors were treated with mch1N11 (a novel mouse chimeric monoclonal antibody that targets PS, cisplatin (cis, or combination after surgery. Tumor relapses and disease progression were decreased 90% by combination therapy compared with a 50% response rate for cis alone (P = .02. Mice receiving postoperative mch1N11 had no wound-related complications or added systemic toxicity in comparison to control animals. Mechanistic studies demonstrated that the effects of mch1N11 were associated with a dense infiltration of inflammatory cells, particularly granulocytes. This strategy was independent of the adaptive immune system. Together, these data suggest that vascular-targeted strategies directed against exposed PS may be a powerful adjunct to postoperative chemotherapy in preventing relapses after cancer surgery.

    Cutaneous radiation therapy (RT)-associated breast angiosarcoma (AS) is a rare consequence of breast RT associated with poor outcomes. Previous small case series have documented high recurrence rates and poor survival. We reviewed our experience and focused on the impact of conservative versus radical resections. Data for patients with RT-associated breast AS evaluated at our institution from 1993 to 2015 who underwent surgery were reviewed. Seventy-six women were diagnosed with RT-associated breast AS at a median 85 months from surgery for invasive breast carcinoma or ductal carcinoma in situ. Thirty-eight underwent mastectomy/wide excision with partial skin resection ("conservative") and 38 underwent resection of all or nearly all previously irradiated skin plus mastectomy ("radical"). The radical group (vs the conservative group) more often had multifocal disease (80% vs 56%, P = 0.04), chemotherapy for AS (58% vs 22%, P radical versus conservative groups were 23% versus 76% (P radical versus conservative groups was 86% versus 46% (P radicality of surgery, and margin were predictive of DSS. For patients with RT-associated breast AS, radical resection was associated with reduced recurrence rates and improved DSS. Although margin was predictive of DSS, multifocality calls into question the reliability of negative margin assessment.

  16. Conservative surgery and radiation for early-stage breast cancer.

    In selected patients with early-stage breast cancer, conservative surgery and radiation represent an alternative equal to mastectomy in terms of local recurrence, distant metastasis, survival, and long-term complications. Patients with early-stage breast cancer who are candidates for conservative surgery and radiation include those whose primary tumor is less than 4 to 5 cm in size without evidence of gross multicentricity or diffuse microcalcifications. Patients with an extensive intraductal component may be appropriate candidates provided that margins of resection are negative. Young age is not a contraindication to the conservative treatment. A preexisting history of collagen vascular disease or prior mantle irradiation for Hodgkin's or non-Hodgkin's lymphoma represents a contraindication to conservative surgery and radiation because of the potential for severe complications. An additional contraindication is the pregnant woman in whom delivery cannot be accomplished before the initiation of radiation. Mammography is essential in the pretreatment evaluation and posttreatment follow-up of the conservatively treated patient. The goal of the pretreatment mammogram is to assess the extent of disease in the ipsilateral breast as well as to evaluate the contralateral breast. In patients who present with microcalcifications, a postbiopsy mammogram before radiation is essential to document complete removal of all malignant-appearing microcalcifications. Mammography is an essential part of the follow-up program in order to detect a recurrence in the treated breast as well as a cancer in the contralateral breast cancer. The optimal interval for follow-up mammography has not been determined, although programs employing mammography on a yearly basis after treatment have been associated with the detection of early recurrences and excellent survival after salvage mastectomy for these recurrences.

    Conditionally replicating adenoviruses (CRAds), or known as replication-selective adenoviruses, were discovered as oncolytic gene vectors several years ago. They have a strong ability of scavenging tumor and lesser toxicity to normal tissue. CRAds not only have a tumor-killing ability but also can combine with gene therapy, radiotherapy, and chemotherapy to induce tumor cell apoptosis. In this paper, we review the structure of CRAds and CRAd vectors and summarize the current application of CRAds in tumor detection as well as in radiotherapy and suicide gene-mediating chemotherapy. We also propose further research strategies that can improve the application value of CRAds, including enhancing tumor destruction effect, further reducing toxic effect, reducing immunogenicity, constructing CRAds that can target tumor stem cells, and trying to use mesenchymal stem cells (MSCs) as the carriers for oncolytic adenoviruses. As their importance to cancer diagnosis, gene-radiation, and chemotherapy, CRAds may play a considerable role in clinical diagnosis and various cancer treatments in the future.

    Objective To measure the scattered radiation dose at different positions simulating hip surgery. Materials and Methods We simulated fluoroscopy-assisted hip surgery in order to study the distribution of scattered radiation in the operating room. To simulate the patient, we used a anthropomorphic whole-body phantom, and we used an X-ray-specific detector to quantify the radiation. Radiographs were obtained with a mobile C-arm X-ray system in continuous scan mode, with the tube at 0º (configuration 1) or 90º (configuration 2). The operating parameters employed (voltage, current, and exposure time) were determined by a statistical analysis based on the observation of orthopedic surgical procedures involving the hip. Results For all measurements, higher exposures were observed in configuration 2. In the measurements obtained as a function of height, the maximum dose rates observed were 1.167 (± 0.023) µSv/s and 2.278 (± 0.023) µSv/s in configurations 1 and 2, respectively, corresponding to the chest level of health care professionals within the operating room. Proximal to the patient, the maximum values were recorded in the position occupied by the surgeon. Conclusion We can conclude that, in the scenario under study, health care professionals workers are exposed to low levels of radiation, and that those levels can be reduced through the use of personal protective equipment.

    Retinoblastoma (RB) is a rare malignancy affecting the pediatric population. Intravenous chemotherapy is the longstanding delivery method, although intra-arterial (IA) chemotherapy is gaining popularity given the reduced side effects compared with systemic chemotherapy administration. Given the sensitivity of the target organ, patient age, and secondary tumor susceptibility, a premium has been placed on minimizing procedural related radiation exposure. To reduce patient x-ray dose during the IA infusion procedure, customized surgical methods and fluoroscopic techniques were employed. The routine fluoroscopic settings were changed from the standard 7.5 pulses/s and dose level to the detector of 36 nGy/pulse, to a pulse rate of 4 pulses/s and detector dose to 23 nGy/pulse. The angiographic dose indicators (reference point air kerma (Ka) and fluoroscopy time) for a cohort of 10 consecutive patients (12 eyes, 30 infusions) were analyzed. An additional four cases (five eyes, five infusions) were analyzed using dosimeters placed at anatomic locations to reflect scalp, eye, and thyroid dose. The mean Ka per treated eye was 20.1±11.9 mGy with a mean fluoroscopic time of 8.5±4.6 min. Dosimetric measurements demonstrated minimal dose to the lens (0.18±0.10 mGy). Measured entrance skin doses varied from 0.7 to 7.0 mGy and were 73.4±19.7% less than the indicated Ka value. Ophthalmic arterial melphalan infusion is a safe and effective means to treat RB. Modification to contemporary fluoroscopic systems combined with parsimonious fluoroscopy can minimize radiation exposure. Published by the BMJ Publishing Group Limited.

    Purpose: The purpose of this study was to investigate the dose-effect relation between acute esophageal toxicity (AET) and the dose-volume parameters of the esophagus after intensity modulated radiation therapy (IMRT) and concurrent chemotherapy for patients with non-small cell lung cancer (NSCLC). Patients and Methods: One hundred thirty-nine patients with inoperable NSCLC treated with IMRT and concurrent chemotherapy were prospectively analyzed. The fractionation scheme was 66 Gy in 24 fractions. All patients received concurrently a daily dose of cisplatin (6 mg/m Superscript-Two ). Maximum AET was scored according to Common Toxicity Criteria 3.0. Dose-volume parameters V5 to V70, D{sub mean} and D{sub max} of the esophagus were calculated. A logistic regression analysis was performed to analyze the dose-effect relation between these parameters and grade {>=}2 and grade {>=}3 AET. The outcome was compared with the clinically used esophagus V35 prediction model for grade {>=}2 after radical 3-dimensional conformal radiation therapy (3DCRT) treatment. Results: In our patient group, 9% did not experience AET, and 31% experienced grade 1 AET, 38% grade 2 AET, and 22% grade 3 AET. The incidence of grade 2 and grade 3 AET was not different from that in patients treated with CCRT using 3DCRT. The V50 turned out to be the most significant dosimetric predictor for grade {>=}3 AET (P=.012). The derived V50 model was shown to predict grade {>=}2 AET significantly better than the clinical V35 model (P<.001). Conclusions: For NSCLC patients treated with IMRT and concurrent chemotherapy, the V50 was identified as most accurate predictor of grade {>=}3 AET. There was no difference in the incidence of grade {>=}2 AET between 3DCRT and IMRT in patients treated with concurrent chemoradiation therapy.

    AIM: To explore whether intensity modulated radiation therapy (IMRT) in combination with chemotherapy could increase radiation dose to gross tumor volume without severe acute radiation related toxicity by decreasing the dose to the surrounding normal tissue in patients with locally advanced pancreatic cancer.METHODS: Twenty-one patients with locally advanced pancreatic cancer were evaluated in this clinical trial,Patients would receive the dose of IMRT from 21Gy to 30Gy in 7 to 10 fractions within two weeks after conventional radiotherapy of 30Gy in 15 fractions over 3 weeks. The total escalation tumor dose would be 51, 54,57, 60Gy, respectively. 5-fluororacil (5-FU) or gemcitabine was given concurrently with radiotherapy during the treatment course.RESULTS: Sixteen patients who had completed the radiotherapy plan with doses of 51Gy (3 cases), 54Gy (3 cases), 57Gy (3 cases) and 60Gy (7 cases) were included for evaluation. The median levels of CA19-9 prior to and after radiotherapy were 716 U/ml and 255 U/ml respectively (P<0.001) in 13 patients who demonstrated high levels of CA19-9 before radiotherapy. Fourteen patients who suffered from pain could reduce at least 1/3-1/2 amount of analgesic intake and 5 among these patients got complete relief of pain. Ten patients improved in Kamofsky performance status (KPS). The median follow-up period was 8 months and one-year survival rate was 35 %. No patient suffered more than grade Ⅲ acute toxicities induced by radiotherapy.CONCLUSION: Sixty Gy in 25 fractions over 5 weeks with late course IMRT technique combined with concurrent 5-FU chemotherapy can provide a definitely palliative benefit with tolerable acute radiation related toxicity for patients with advanced pancreatic cancer.

    Purpose: To identify a cohort of women treated with neoadjuvant chemotherapy and mastectomy for whom postmastectomy radiation therapy (PMRT) may be omitted according to the projected risk of local-regional failure (LRF). Methods and Materials: Seven breast cancer physicians from University of California cancer centers created 14 hypothetical clinical case scenarios, identified, reviewed, and abstracted the available literature (MEDLINE and Cochrane databases), and formulated evidence tables with endpoints of LRF, disease-free survival, and overall survival. Using the American College of Radiology appropriateness criteria methodology, appropriateness ratings for postmastectomy radiation were assigned for each scenario. Finally, an overall summary risk assessment table was developed. Results: Of 24 sources identified, 23 were retrospective studies from single institutions. Consensus on the appropriateness rating, defined as 80% agreement in a category, was achieved for 86% of the cases. Distinct LRF risk categories emerged. Clinical stage II (T1-2N0-1) patients, aged >40 years, estrogen receptor-positive subtype, with pathologic complete response or 0-3 positive nodes without lymphovascular invasion or extracapsular extension, were identified as having {<=}10% risk of LRF without radiation. Limited data support stage IIIA patients with pathologic complete response as being low risk. Conclusions: In the absence of randomized trial results, existing data can be used to guide the use of PMRT in the neoadjuvant chemotherapy setting. Using available studies to inform appropriateness ratings for clinical scenarios, we found a high concordance of treatment recommendations for PMRT and were able to identify a cohort of women with a low risk of LRF without radiation. These low-risk patients will form the basis for future planned studies within University of California Athena Breast Health Network.

    Full Text Available In light of the possible adverse effects of radiation on hearing, we conducted a study to evaluate the long-term sensorineural hearing status following radiotherapy (RT in patients suffering from nasopharyngeal carcinoma. Audiologic examinations were performed at regular intervals before and after RT. We also analyzed the effects of age, chemotherapy, pre-RT hearing status, and post-RT otitis media with effusion (OME on post-RT hearing change. A total of 150 patients (261 ears were enrolled in this study and followed up for a mean of 43.8 months. After RT, 8.9-28.8% of ears had at least a 10 dB loss in bone conduction threshold at speech frequency, which was defined as an average of hearing threshold at 0.5 kHz, 1 kHz, and 2 kHz, while the percentage was 18-34.2% at 4 kHz. Patient age was related to these changes at speech frequency, and the presence of post-RT OME was related to significant loss at both speech frequency and 4 kHz. Pre-RT hearing status and chemotherapy did not influence hearing change. To sum up, sensorineural hearing loss began as early as after completion of RT. Early changes may be transient, but the effect of radiation on hearing tended to be chronic and progressive.

    Peritoneal mesothelioma is a rare disease with poor prognosis. The present study reports single center experience with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy with oxaliplatin (HIPEC-OX) over an eight-year period. Prospectively collected data of all consecutive patients with epithelial or multicystic peritoneal mesothelioma from August 2004 to October 2012 was analyzed. Patients with sarcomatoid or biphasic peritoneal mesothelioma were not included due to general poor prognosis. Treatment consisted in CRS and HIPEC-OX (460 mg/m(2)) at 43 °C during 30 min. For statistical analysis, Kaplan-Meier survival curves were plotted and compared using log-rank tests. Cox proportional-hazards regression model was used to analyze the influence of different variables on survival. Nineteen patients with peritoneal mesothelioma underwent laparotomy with CRS and HIPEC-OX with curative intent (15 epithelial, and 4 multicystic). Mean follow-up was 36.7 months. The estimated one-year and three-year overall survival rates were respectively 100% and 91%. The estimated one-year and three-year disease-free survival rates were respectively 77% and 50%. Complications were graded according to the Clavien-Dindo classification [1] and major complications occurred in 57% of cases. There was no postoperative mortality. Histological grade was not a prognostic factor of disease-free survival (p = 0.37). When comparing survival results as well as morbidity-mortality rates, the present study shows that CRS and HIPEC-OX is a valid treatment for peritoneal mesothelioma. Copyright © 2014 Elsevier Ltd.

    Between 1971 and 1976, 64 patients less than 18 years of age with non-Hodgkin's lymphoma were treated at Boston's Children's Hospital Medical Center-Joint Center for Radiation Therapy. A multimodality approach was used, consisting of radiation therapy (3500 to 4500 rad), surgery, and chemotherapy. Since 1973, all patients have received a regimen initially comprising Adriamycin, Prednisone, 6-Mercaptopurine, Vincristine, and L-Asparaginase. Methotrexate was substituted for Adriamycin following a cumulative total dose of 450 mg/m/sup 2/. The 5-year actuarial survival for all patients was 61%, while relapse-free survival was 54%. The actuarial and relapse-free survival for patients presenting with localized disease was 75% and 72%, respectively. Median follow-up was 40 months and all relapses occurred within 24 months of initial therapy. A multidisciplinary approach, such as the current regimen, offers a good prognosis for this disease.

    Orthopedists are exposed to considerable radiation dose during orthopedic surgeries procedures. The staff is not well trained in radiation protection aspects and its related risks. In Sudan, regular monitoring services are not provided for all staff in radiology or interventional personnel. It is mandatory to measure staff and patient exposure in order to radiology departments. The main objectives of this study are: to measure the radiation dose to patients and staff during (i) Dynamic Hip Screw (Dhs) and (i i) Dynamic Cannula Screw (Dcs); to estimate the risk of the aforementioned procedures and to evaluate entrance surface dose (ESD) and organ dose to specific radiosensitive patients organs. The measurements were performed in Medical Corps Hospital, Sudan. The dose was measured for unprotected organs of staff and patient as well as scattering radiation. Calibrated Thermoluminescence dosimeters (TLD-Gr-200) of lithium fluoride (LiF:Mg, Cu,P) were used for ESD measurements. TLD signal are obtained using automatic TLD Reader model (Plc-3). The mean patients doses were 0.46 mGy and 0.07 for Dhs and Dcs procedures, respectively. The mean staff doses at the thyroid and chest were 4.69 mGy and 1.21 mGy per procedure. The mean radiation dose for staff was higher in Dhs compared to Dcs. This can be attributed to the long fluoroscopic exposures due to the complication of the procedures. Efforts should be made to reduce radiation exposure to orthopedic patients, and operating surgeons especially those with high work load. Staff training and regular monitoring will reduce the radiation dose for both patients and staff. (Author)

    Background: Neither surgical advances nor those in therapeutic radiology have been able to significantly reduce the mortality related to esophageal carcinomas. The results of combining: first surgery, then radiation therapy, which have been dissatisfactory for decades, encourage therapeutic concepts involving a variety of modalities. Patients and Methods: For 50 patients with unresectable locally advanced esophageal carcinomas, a palliative concurrent chemotherapy and radiation therapy was carried out according to the ''intent to treat'' principle. The aim was a minimal dose of 40 Gy. The concurrent chemotherapy was carried out using cisplatin/5-FU during the 1st and 4th weeks of radiation therapy. In the case of partial or complete remission, the chemotherapy was to be continued as maintenance therapy with a maximum of four cycles. In the case of no change or minor response, instead of maintenance chemotherapy, the dose of local radiation was to be increased by means of brachytherapy. Results: The median survival rate for the entire population under study was 8.7 months. The survival rates of 1, 2, 3, 4, and 5 years were, respectively, 38%, 20.5%, 13.7%, 6.8%, and 6.8%. The remission rates were as follows: NC: 14 patients (28%), PR: 32 patients (64%), CR: 4 patients (8%). 17 patients (34%) tolerated the full concurrent chemotherapy; only twelve patients (24%) tolerated supportive chemotherapy. The following factors exhibited a significant correlation to survival: the intensity of the chemotherapy, the Karnofsky index, the age of the patients, and the improvement of oral food intake. Conclusions: The concurrent chemotherapy was toxic and the benefit to the patients questionable. At best, meta-analyses of randomized studies along the lines of ''evidence-based medicine'' demonstrate for concurrent chemotherapy and radiation therapy an improvement of 2-year survival rates, but with these also involving a high level of toxicity

    Poorly differentiated neuroendocrine carcinoma has a poor prognosis, especially when associated with distant metastasis. A 60-year-old man was admitted to a private hospital because of dyspnea at work in 2007. Computed tomography revealed lung infarction and a right adrenal tumor sized 12 cm in diameter that was tightly compressed against the inferior vena cava (IVC). Moreover, multiple lymph node metastases around the celiac axis and a solitary liver metastasis at the lateral segment were observed. Thus, we planned chemotherapy without surgery. We selected a combination therapy of irinotecan (CPT-11) and cisplatin (CDDP) (i.e., IP therapy): administration of CDDP [60 mg/m(2) body surface area (BSA)] on day 1 plus CPT-11 (80 mg/m(2)) BSA on days 1 and 8. Thereafter, this protocol was repeated at 3-week intervals. After 15 months of this chemotherapy strategy, the whole lesions showed a partial response by RECIST. The primary tumor had shrunk to 4.2 cm in diameter. In November 2008, we planned surgery to perform resection of the whole lesions. Histological diagnosis of the specimen was a poorly differentiated neuroendocrine carcinoma based on the immunostaining features, i.e., synaptophysin- and chromogranin positive. There were no viable tumor cells at the dissected lymph nodes or at the liver tumor. After surgery, CPT-11 administration was continued. The patient has remained well for 9 months without recurrence.

  11. The role of induction chemotherapy before radiation therapy in non-operative management of stage III NSCLC.

    Radiation therapy alone has been 'standard' management of patients with Stage III non-small cell lung cancer for several decades. Palliative benefits are routinely achieved but significant survival benefits have not been documented. Patterns of failure in Stage III patients emphasize the need to pursue better treatment for both local macroscopic disease and distant micrometastatic sites. Improved control in both areas will be necessary to meaningfully enhance outcome for the universe of Stage III NSCLC patients. Several randomized trials show a significant survival benefit when cisplatin-containing induction chemotherapy is administered prior to locoregional treatment. In the favorable subset of Stage III patients selected for study by CALGB, the surviving fraction at 2-5 years post-therapy was > or = 2-fold larger in the chemoradiation group than in the cohort treated with radiation alone. The French trial documented a significant decrease in distant metastases rate among the chemotherapy treated patients. In all the trials where patterns of failure are discussed, local disease persistence is the overwhelming rule. Future trials must evaluate improved induction chemotherapy approaches. Stage III patients are an ethical population in which to test induction therapy with new drug combinations randomized against already 'active' regimens for comparative efficacy. End points would be initial response rates, patterns of failure, and overall survival. The feasibility of high-dose chemotherapy regimens with growth factor and hematopoietic support followed by aggressive radiation must be tested. If feasible, trials randomizing high dose versus conventional dose induction programs within the context of sequential multimodality therapy should follow. Intensified radiation approaches such as hyperfractionation or CHART should be paired with active concurrent chemotherapy following induction chemotherapy alone. Pursuit of these approaches over the next several years will

    Purpose: The optimal sequence of radiotherapy and chemotherapy in breast-conserving therapy is unknown. Methods and Materials: From 1983 through 2007, a total of 641 patients with 653 instances of breast-conserving therapy (BCT), received both chemotherapy and radiotherapy and are the basis of this analysis. Patients were divided into three groups. Groups A and B comprised patients treated before 2005, Group A radiotherapy first and Group B chemotherapy first. Group C consisted of patients treated from 2005 onward, when we had a fixed sequence of radiotherapy first, followed by chemotherapy. Results: Local control did not show any differences among the three groups. For distant metastasis, no difference was shown between Groups A and B. Group C, when compared with Group A, showed, on univariate and multivariate analyses, a significantly better distant metastasis-free survival. The same was noted for disease-free survival. With respect to disease-specific survival, no differences were shown on multivariate analysis among the three groups. Conclusion: Radiotherapy, as an integral part of the primary treatment of BCT, should be administered first, followed by adjuvant chemotherapy.

    CNS germinomas have an excellent prognosis with radiation therapy alone. However, in children, volume and dose of CNS radiation are associated with neurocognitive and neuroendocrine sequelae. Our objective was to determine long-term outcomes of our cohort who received chemotherapy and reduced radiation. This retrospective cohort study analyzed treatment and outcome of intracranial germinoma patients consecutively treated at Sick Kids, Toronto, Canada, from January 2000 to December 2013. 24 children (13 male, 11 female; median age 13.36 years) were identified. Median follow up was 61 months (range 1-144 months). Tumor location was suprasellar (n = 9), bifocal (8), pineal (6), and basal ganglia (1). Three children showed dissemination on imaging. 2/24 had only elevated serum human chorionic gonadotropin, 3/24 only elevated lumbar cerebrospinal fluid (CSF) hCG, and 2/24 had both elevated serum and lumbar CSF hCG. 23/24 children completed treatment and received multi-agent chemotherapy followed by either ventricular radiation (2340-2400 cGy) (n = 9), ventricular radiation + boost (1600 cGy) (n = 8), whole brain (2340 cGy) (n = 3), focal (4000 cGy) (n = 2) or craniospinal radiation (2340 cGy) (n = 1). Five-year progression free and overall survival was 96 and 100 % respectively. 8/24 patients with ventricular radiation ± boost (2340/4000 cGy) displayed stable full scale intelligence quotient over a mean interval of 3 years following radiation, but showed declined processing speed. In this limited experience, excellent 5-year overall survival rates were achieved with chemotherapy followed by reduced whole ventricular radiation even if ventricular radiation was delivered without boost.

    The use of targeted intraoperative radiotherapy (TARGIT-IORT) as a tumour bed boost during breast-conserving surgery (BCS) for breast cancer has been reported since 1998. We present its use in patients undergoing breast conservation following neoadjuvant therapy (NACT). In this retrospective study involving 116 patients after NACT we compared outcomes of 61 patients who received a tumour bed boost with IORT during lumpectomy versus 55 patients treated in the previous 13 months with external (EBRT) boost. All patients received whole breast radiotherapy. Local recurrence-free survival (LRFS), disease-free survival (DFS), distant disease-free survival (DDFS), breast cancer mortality (BCM), non-breast cancer mortality (NBCM) and overall mortality (OS) were compared. Median follow up was 49 months. The differences in LRFS, DFS and BCM were not statistically significant. The 5-year Kaplan-Meier estimate of OS was significantly better by 15% with IORT: IORT 2 events (96.7%, 95%CI 87.5-99.2), EBRT 9 events (81.7%, 95%CI 67.6-90.1), hazard ratio (HR) 0.19 (0.04-0.87), log rank p = 0.016, mainly due to a reduction of 10.1% in NBCM: IORT 100%, EBRT 89.9% (77.3-95.7), HR (not calculable), log rank p = 0.015. The DDFS was as follows: IORT 3 events (95.1%, 85.5-98.4), EBRT 12 events (69.0%, 49.1-82.4), HR 0.23 (0.06-0.80), log rank p = 0.012. IORT during lumpectomy after neoadjuvant chemotherapy as a tumour bed boost appears to give results that are not worse than external beam radiotherapy boost. These data give further support to the inclusion of such patients in the TARGIT-B (boost) randomised trial that is testing whether IORT boost is superior to EBRT boost. (orig.)

    172 patients who had had mastectomy for breast cancer were treated by repeated adjuvant chemotherapy, either with phenylalanine mustard (P.A.M.) or a combination of cyclophosphamide, 5-fluorouracil, and prednisone (C.F.P.) with and without radiotherapy. Tumours recurred significantly more frequently and mortality tended to be higher in P.A.M.-treated patients than in patients on other treatment. The interval between surgery and disease recurrence was significantly shorter for P.A.M.-treated premenopausal but not postmenopausal patients than for patients of equivalent menstrual status treated with C.F.P. with or without radiation. The associations in premenopausal patients between the mode of treatment and both survival and the disease-free interval were significant before and after adjustment for variations between the treatment groups in the number of involved lymph nodes and the size of the primary tumour.

    Neoadjuvant chemotherapy [NACT] followed by radical hysterectomy is an alternative therapeutic option to concurrent chemotherapy-radiotherapy for locally advanced cervical cancer. However there are very few data about the effectiveness of any post-operative treatment in this clinical setting. The purpose of this study was to correlate the patterns of recurrence and the clinical outcomes of cervical cancer patients who received NACT, with postoperative adjuvant treatment. This retrospective multicenter study included 333 patients with FIGO stage Ib2-IIb cervical cancer who underwent platinum-based NACT followed by radical surgery. Pathological responses were retrospectively assessed as complete; optimal partial; and suboptimal response. Overall optimal response rate was the sum of complete and optimal partial response rates. On the whole series, recurrence-free survival was significantly longer in patients who achieved an overall optimal response than in those who did not (ptreatment for FIGO stage Ib2-IIb cervical cancer do not need any further treatment. Additional cycles of chemotherapy could be of benefit for patients with suboptimal response and intra-cervical residual disease. Both adjuvant chemotherapy and adjuvant radiation treatments do not seem to improve the clinical outcome of patients with extra-cervical residual disease compared to no further treatment.

    Peritoneal carcinomatosis (PC) has been traditionally considered a terminal disease with median survivals reported in the literature of 6 to 12 months. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) are playing an ever increasing role in the treatment of these patients. Excellent results have been achieved in well-selected patients but there is a very steep learning curve when starting a new program. A program for peritoneal surface malignancies in which patients with PC of gastrointestinal or gynecological origin were treated using multimodality therapy with combinations of systemic therapy, cytoreductive surgery (CRS), and HIPEC was initiated in December 2007 at "Hospital Regional de Alta Especialidad de Oaxaca," Mexico. We present the results of our initial experience. From December 2007 to February 2011, 26 patients were treated with CRS and HIPEC. There were 21 female patients. Most common indication (46%) was recurrent ovarian cancer. Mean duration of surgery was 260 minutes. Mean Peritoneal Cancer Index was 9. Twenty-three (88.5%) patients had a complete cytoreduction. Major morbidity and mortality rates were 19.5 and 3.8 per cent, respectively. Mean hospital stay was 8 days. At a mean follow-up of 20 months, median survival has not been reached. Rigorous preoperative workup, strict selection criteria, and mentoring from an experienced cytoreductive surgeon are mandatory and extremely important when starting a center for PC.

    Seventeen patients with stage IA non-Hodgkin's lymphoma of the Waldeyer's ring were treated with radiation therapy with or without chemotherapy. All lesions were judged as having intermediate grade malignancy in the Working Formulation. Eight patients received combined treatment with three cycles of cylcophosphamide, doxorubicin, vincristine and prednison (CHOP) and radiation therapy with 30 to 40 Gy. Another 9 patients were treated with radiation therapy 40 to 60 Gy alone. After a median follow-up of 69 months, all 8 patients, treated with combined modality were alive and relapse-free whereas 4 of the 9 treated with irradiation alone had relapsed. All relapses occurred transdiaphragmatically. Two of the 4 relapsing patients were saved, but the other two died of the disease. The 5-year relapse-free and cause-specific survival rates were 100% and 100% in the combined modality group, and 56% and 76% in the radiation therapy alone group (relapse-free: p=0.04, cause-specific: p=0.16). There were no serious complications related to treatment, although most patients complained of mouth dryness and most patients given CHOP had paresthesia. Our opinion was that the total impact of these two side-effects on quality of life was less pronounced after combined modality than after radiation therapy alone. Limited chemotherapy and radiation therapy seemed to be more beneficial than radiation therapy alone not only in relapse-free survival but also in quality of life after treatment. (orig.).

  20. Chemotherapy-Induced and/or Radiation Therapy-Induced Oral Mucositis-Complicating the Treatment of Cancer

    Full Text Available The term mucositis is coined to describe the adverse effects of radiation and chemotherapy treatments. Mucositis is one of the most common adverse reactions encountered in radiation therapy for head and neck cancers, as well as in chemotherapy, in particular with drugs affecting DNA synthesis (Sphase-specific agents such as fluorouracil, methotrexate, and cytarabine. Mucositis may limit the patient's ability to tolerate chemotherapy or radiation therapy, and nutritional status is compromised. It may drastically affect cancer treatment as well as the patient's quality of life. The incidence and severity of mucositis will vary from patient to patient. It will also vary from treatment to treatment. It is estimated that there is 40% incidence of mucositis in patients treated with standard chemotherapy and this will not only increase with the number of treatment cycles but also with previous episodes. Similarly, patients who undergo bone marrow transplantation and who receive high doses of chemotherapy have a 76% chance of getting mucositis. Patients receiving radiation, in particular to head and neck cancers, have a 30% to 60% chance. The exact pathophysiology of development is not known, but it is thought to be divided into direct and indirect mucositis. Chemotherapy and/or radiation therapy will interfere with the normal turnover of epithelial, cells leading to mucosal injury; subsequently, it can also occur due to indirect invasion of Gram-negative bacteria and fungal species because most of the cancer drugs will cause changes in blood counts. With the advancement in cytology, a more precise mechanism has been established. With this understanding, we can select and target particular mediators responsible for the mucositis. Risk factors such as age, nutritional status, type of malignancy, and oral care during treatment will play important roles in the development of mucositis. Many treatment options are available to prevent and treat this

    Three-dimensional microtomography has the potential to examine complete bones of small laboratory animals with very high resolution in a non-invasive way. One of the side effects caused by some chemotherapy drugs is the induction of amenorrhea, temporary or not, in premenopausal women, with a consequent decrease in estrogen production, which can lead to bone changes. In the present work, the femur heads of rats treated with chemotherapy drugs were evaluated by 3D histomorphometry using synchrotron radiation microcomputed tomography. Control animals were also evaluated for comparison. The 3D tomographic images were obtained at the SYRMEP (SYnchrotron Radiation for MEdical Physics) beamline at the Elettra Synchrotron Laboratory in Trieste, Italy. Results showed significant differences in morphometric parameters measured from the 3D images of femur heads of rats in both analyzed groups.

    A man in his 60s was admitted for the treatment of advanced cervical esophageal cancer with metastasis to the lymph nodes and advanced tongue cancer with metastasis to the lymph nodes. Esophageal cancer was suspected to have invaded the trachea. The tongue cancer was located on the left side and had invaded beyond the median line of the tongue. Both cancers were pathologically diagnosed as squamous cell carcinomas. Therefore, it was determined that pharyngo-laryngo- esophagectomy and total glossectomy were required prior to the treatment. However, after 2 courses of docetaxel/cisplatin/ 5-FU combined induction chemotherapy, both cancers remarkably decreased; consequently, an esophagectomy to preserve laryngeal function and partial glossectomy could be performed simultaneously. The patient is well without recurrence 1 year post-surgery.

    The overexpression of mutant p53 stimulates serum p53 antibody production in patients with colorectal carcinoma even in superficial tumors. Although the short-term perioperative monitoring of serum p53 antibody titers is reported to be useful in predicting tumor recurrence and patient survival in colorectal carcinoma, the clinical utility of the long-term monitoring of serum p53 antibody titers in patients with colorectal cancer remains unknown. Here, we report the 3-year monitoring of serum p53 antibody titers in a 60-year-old man with rectal cancer, clinical stage IV (T2N2M1b, lung and liver metastases), who was treated with chemotherapy and surgery. Screening tests for CEA (29.4 ng/ml), CA19-9 (41.1 U/ml), and serum p53 antibody (2170 U/ml) were positive before treatment. After chemotherapy with mFOLFOX6 + bevacizumab (B-mab), CEA and CA19-9 decreased to the normal range. However, serum p53 antibody titer remained positive (283 U/ml). After low anterior resection, the serum p53 antibody titer still remained positive (63.4 U/ml). Serum p53 antibody titer significantly changed and was associated with treatment response and tumor recurrence. In the last 6 months of the patient's life, serum p53 antibody titer gradually decreased, which possibly reflects the modification of the patient's immune response to p53 antigens.

    Diffuse malignant peritoneal mesothelioma is a rare, aggressive disease. Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) have improved outcomes where systemic chemotherapy has not succeeded. In this study, we compare outcomes of patients treated with mitomycin or carboplatin as perfusate. In this retrospective study, 47 procedures (CRS + HIPEC) were conducted on 44 patients between March 2003 and August 2010 with either mitomycin or carboplatin. χ(2) and Student's t test were used for comparison of clinicopathological variables and Kaplan-Meier curves and log rank test were used to compare overall survival. Median survival of the mitomycin group was 18 months with 1- and 5-year survivals of 72.3 and 27.3 per cent, respectively. Median survival of the carboplatin group was not reached and 1- and 5-year survivals were 89.7 and 62.5 per cent, respectively (P = 0.014). Mean hospital and intensive care unit length of stay was 18.9 and 8.7 days in the mitomycin group and 12.5 and 2.3 days in the carboplatin group (P = 0.0069). Mean number of packed red blood cell units transfused was higher in the mitomycin group compared with the carboplatin group (3.54 vs 0.83, P mitomycin.

Patients were divided into young (aged ≤35 years, n = 177 and older (aged >35 years, n = 837 groups. We compared the short-term responses and survival rates between the groups. The five-year disease-free survival (DFS and overall survival (OS rates were stratified by age, NACT response, and FIGO stage.The overall response rate was 86.8% in the young group and 80.9% in the older group. The young patients had an earlier FIGO stage (P<0.001, a higher rate of adenocarcinoma (P = 0.022, and more lymph node metastasis (P = 0.033 than the older patients. The presence of adenocarcinoma as the histological type (P = 0.024 and positive lymph node metastasis (P<0.001 were identified as independent risk factors for survival. When stratified by age and clinical response, young patients with no response to NACT had a worse clinicopathological condition compared with the other subgroups. Compared with non-responders, responders to NACT had a higher five-year DFS rate (80.1% versus 71.8%; P = 0.019 and OS rate (82.6% versus 71.8%; P = 0.003 among the young patients but not among the older patients.Responders to NACT aged 35 years or younger benefitted the most from NACT, while the young non-responders benefitted the least.

    The addition of PCV (procarbazine, lomustine, vincristine) chemotherapy to radiotherapy (RT) for patients with high-risk (≥ 40 years old or sub-totally resected) low-grade glioma (LGG) results in an absolute median survival benefit of over 5 years. We evaluated the cost-effectiveness of this treatment strategy. A decision tree with an integrated three-state Markov model was created to follow patients with high risk LGG after surgery treated with RT vs. RT+PCV. Patients existed in one of 3 health states: stable, progressive, and dead. Survival and freedom from progression were modeled to reflect the results of RTOG 9802 using time-dependent transition probabilities. Health utility values and costs of care were derived from the literature and national registry databases. Analysis was conducted from the healthcare perspective. Deterministic and probabilistic sensitivity analysis explored uncertainty in model parameters. Modeled outcomes demonstrated agreement with clinical data in expected benefit of addition of PCV to RT. The addition of PCV to RT yielded an incremental benefit of 4.77 quality-adjusted life-years (QALYs) (9.94 for RT+PCV vs. 5.17 for RT alone) at an incremental cost of $48,635 ($188,234 for RT+PCV vs. $139,598 for RT alone), resulting in an incremental cost-effectiveness ratio of $10,186 per QALY gained. Probabilistic sensitivity analysis demonstrates that within modeled distributions of parameters, RT+PCV has 99.96% probability of being cost-effectiveness at a willingness-to-pay threshold of $100,000 per QALY. The addition of PCV to RT is a cost-effective treatment strategy for patients with high-risk LGG.

    This study was performed to evaluate the disease-free survival and risk factors of recurrence in early breast cancer patients who have undergone breast conserving surgery and radiation therapy. Materials and Methods: From March 1997 to December 2002, 77 breast cancer patients who underwent breast conserving surgery and radiation therapy were reviewed retrospectively. The median follow-up time was 58.4 months (range 43.8-129.4 months) and the mean subject age was 41 years. The frequency distribution of the different T stages, based on the tumor characteristics was 38 (49.3%) for T1, 28 (36.3%) for T2, 3 for T3, 7 for Tis and 1 for an unidentified sized tumor. In addition, 52 patients (67.5%) did not have axillary lymph metastasis, whereas 14 patients (18.1%) had 1-3 lymph node metastases and 3 (0.03%) had more than 4 lymph node metastases. The resection margin was negative in 59 patients, close ({<=}2 mm) in 15, and positive in 4. All patients received radiation therapy at the intact breast using tangential fields with a subsequent electron beam boost to the tumor bed at a total dose ranging from 59.4 Gy to 66.4 Gy. Patients with more than four positive axillary lymph nodes received radiation therapy (41.4-60.4 Gy) at the axillary and supraclavicular area. Chemotherapy was administered in 59 patients and tamoxifen or fareston was administered in 29 patients. Results: The 5 year overall survival and disease-free survival rates were 98.08% and 93.49%, respectively. Of the 77 patients, a total of 4 relapses (5.2%), including 1 isolated supraclavicular relapse, 1 supraclavicular relapse with synchronous multiple distant relapses, and 2 distant relapses were observed. No cases of local breast relapses were observed. Lymph node metastasis or number of metastatic lymph nodes was not found to be statistically related with a relapse (p=0.3289) nor disease-free survival (p=0.1430). Patients with positive margins had a significantly shorter disease-free survival period (p<0

    Purpose: To quantify changes in bone marrow fat fraction and determine associations with peripheral blood cell counts. Methods and Materials: In this prospective study, 19 patients received either highly myelotoxic treatment (radiation therapy plus cisplatin, 5-fluorouracil mitomycin C [FU/MMC], or cisplatin/5-FU/cetuximab) or less myelotoxic treatment (capecitabine-radiation therapy or no concurrent chemotherapy). Patients underwent MR imaging and venipuncture at baseline, midtreatment, and posttreatment visits. We performed mixed effects modeling of the mean proton density fat fraction (PDFF[%]) by linear time, treatment, and vertebral column region (lumbar [L]4-sacral [S]2 vs thoracic [T]10-L3 vs cervical[C]3-T9), while controlling for cumulative mean dose and other confounders. Spearman rank correlations were performed by white blood cell (WBC) counts versus the differences in PDFF(%) before and after treatment. Results: Cumulative mean dose was associated with a 0.43% per Gy (P=.004) increase in PDFF(%). In the highly myelotoxic group, we observed significant changes in PDFF(%) per visit within L4-S2 (10.1%, P<.001) and within T10-L3 (3.93%, P=.01), relative to the reference C3-T9. In the less myelotoxic group, we did not observe significant changes in PDFF(%) per visit according to region. Within L4-S2, we observed a significant difference between treatment groups in the change in PDFF(%) per visit (5.36%, P=.04). Rank correlations of the inverse log differences in WBC versus the differences in PDFF(%) overall and within T10-S2 ranged from 0.69 to 0.78 (P<.05). Rank correlations of the inverse log differences in absolute neutrophil counts versus the differences in PDFF(%) overall and within L4-S2 ranged from 0.79 to 0.81 (P<.05). Conclusions: Magnetic resonance imaging fat quantification is sensitive to marrow composition changes that result from chemoradiation therapy. These changes are associated with peripheral blood cell counts. This study supports a

    Radical trachelectomy is now recognized as a valid treatment option for young women with early-stage cervical cancer with lesions measuring less than 2 cm. However, for women with bulky lesions measuring greater than 2 cm, few data are available in the literature to guide management. There are currently 2 options available: either upfront radical trachelectomy or neoadjuvant chemotherapy followed by fertility-preserving surgery. Overall, both options offer very good oncologic outcome; however, the rate of fertility preservation and obstetrical outcome seem superior after neoadjuvant chemotherapy. Advantages and disadvantages of both options are discussed and a thorough literature review is provided. Issues to be further studied are also outlined.

    Full Text Available BACKGROUND: The effect of neoadjuvant chemotherapy (NAC on Gastric carcinoma (GC has been extensively studied, while its survival and surgical benefits remain controversial. This study aims to perform a meta-analysis of high-quality randomized controlled trials (RCTs, comparing efficacy, safety and other outcomes of NAC followed by surgery with surgery alone (SA for GC. METHODS: We systematically searched databases of MEDLINE, EMBASE, The Cochrane Library and Springer for RCTs comparing NAC with SA when treating GC. Reference lists of relevant articles and reviews, conference proceedings and ongoing trial databases were also searched. Primary outcomes were 3-year and 5-year survival rates, survival time, and total and perioperative mortalities. Secondary outcomes included down-staging effects, R0 resection rate, and postoperative complications. Meta-analysis was conducted where possible comparing items using relative risks (RRs and weighted mean differences (WMDs according to type of data. NAC-related objective response, safety and toxicity were also specifically analyzed. RESULTS: A total of 9 RCTs comparing NAC (n = 511 with SA (n = 545 published from 1995 to 2010 were identified. SA tended to be accompanied with higher overall mortality rate than NAC (46.03% vs 40.61%, RR: 0.83, 95% CI: 0.65-1.06, P = 0.14. Significantly, higher incidence of cases without regional lymph node metastasis observed upon resection were achieved among patients receiving NAC than those undergoing SA (25.68% vs 16.95%, RR: 1.92, 95% CI: 1.20-3.06, P = 0.006. All other parameters were comparable. Of the evaluable patients, 43.0% demonstrated either complete or partial response. The comprehensive NAC-related side-effect rate was 18.2% among patients available for safety assessment. CONCLUSIONS: NAC contributes to lowering nodal stages, and potentially reduces overall mortality. Response rate may be an important influential factor impacting advantages

    AIM: To evaluate the dosimetry, efficacy and toxicity of intensity-modulated radiation therapy (IMRT) and concurrent chemotherapy for patients with locally advanced cervical and upper thoracic esophageal cancer.METHODS: A retrospective study was performed on 7 patients who were definitively treated with IMRT and concurrent chemotherapy. Patients who did not receive IMRT radiation and concurrent chemotherapy were not included in this analysis. IMRT plans were evaluated to assess the tumor coverage and normal tissue avoidance. Treatment response was evaluated and toxicities were assessed.RESULTS: Five- to nine-beam IMRT were used to deliver a total dose of 59.4-66 Gy (median: 64.8 Gy) to the primary tumor with 6-MV photons. The minimum dose received by the planning tumor volume (PTV) of the gross tumor volume boost was 91.2%-98.2% of the prescription dose (standard deviation [SD]: 3.7%-5.7%).tumor volume was 93.8%-104.8% (SD: 4.3%-11.1%)of the prescribed dose. With a median follow-up of 15 mo (range: 3-21 mo), all 6 evaluable patients achieved complete response. Of them, 2 developed local recurrences and 2 had distant metastases, 3 survived with no evidence of disease. After treatment, 2 patients developed esophageal stricture requiring frequent dilation and 1 patient developed tracheal-esophageal fistula.CONCLUSION: Concurrent IMRT and chemotherapy resulted in an excellent early response in patients with locally advanced cervical and upper thoracic esophageal cancer. However, local and distant recurrence and toxicity remain to be a problem. Innovative approaches are needed to improve the outcome.

    Patients who have had curative surgery for lung cancer are at the highest risk of developing a new lung cancer. Individual studies are usually underpowered to describe the clinical characteristics and outcomes in second primary lung cancer (SPLC). The goal of this study is to determine which treatment is best associated with survival in patients who develop a new primary lung cancer. All pathologically proven stage I lung cancer cases that received cancer-directed surgery included in the Surveillance Epidemiology and End Results database between 2004 and 2010 were selected. Cases that received radiation therapy were excluded. Cases that developed a SPLC 6 or more months after the diagnosis of the first cancer were analyzed. The original data set consisted of 9564 stage I lung cancer cases treated with surgery; 520 of them developed a second primary, and completed data were available for 494 of them. Stage I disease was diagnosed in 272 patients with SPLCs (58.5%); 45.8% of these underwent cancer surgery alone, and 31.6% received radiation alone. Surgery was performed more frequently in early stages and younger patients. Surgical patients had statistically significant longer survival than patients treated with radiation (log-rank P < 0.0001) or not treated with surgery or radiation (log-rank P < 0.0001). The incidence of SPLCs was 5.4%. Stage I second primaries had improved survival when compared with later stage disease, and surgery conferred an increased survival benefit as compared with radiation.

    We describe a retrospective series of patients with advanced head-and-neck cancer who were treated with induction chemotherapy followed by radical chemo-radiation. Patients treated with two cycles of induction chemotherapy followed by definitive chemo-radiation for squamous cell carcinoma of the head-and-neck region, from 2001 - 2006 at the Royal Marsden Hospital, formed the basis of this study. Cisplatin (75 mg m(-2)) on day 1 and 5-FU (1000 mg m(-2)) day 1 - 4 was the standard regimen used for induction treatment. Cisplatin (100 mg m(-2)) on day 1 and day 29 was used for concomitant treatment. The radiation was delivered using conformal technique. Tissues containing macroscopic and microscopic disease were treated to doses of 65 Gray (Gy) in 30 fractions and 50 Gy in 25 fractions, respectively. Data on patterns of relapse and acute toxicity (NCICTCv.3.0) were collected. A total of 129 patients were included, median age was 58 (range: 27 - 78). The site of tumour was: oropharynx 70 (54%), larynx 30 (23%), hypopharynx 24 (19%) and other 5 (4%). The median follow-up was 19 months (range: 4 - 58). Local control, disease-specific survival and overall survival at 2 years were 71%, 68% and 63%, respectively. The distant recurrence rate at 2 years was 9%. Ten patients required dose reduction during induction chemotherapy due to toxicity. The dose of 5-FU was reduced in six patients and that of cisplatin in four patients. The incidence of grade 3/4 toxicity was: neutropenia 5%, thrombocytopenia 1%, nausea and vomiting 3%. One cycle of concurrent cisplatin was omitted in 23 patients due to toxicity. Full-dose radiotherapy was administered to 98% of patients. The incidence of grade 3/4 toxicity was: skin 20%, dysphagia 65%, mucositis 60%, neutropenia 3%, anaemia 1%, nausea and vomiting 4%, nephrotoxicity 1%. Induction chemotherapy followed by radical chemo-radiation is a safe and tolerable regimen in the treatment of advanced head-and-neck cancer. Distant recurrence rates

    Since the extract from berries of Aronia melanocarpa presents antioxidative properties in plasma and in blood platelets, not only from healthy group, but also from patients with benign breast diseases and in patients with invasive breast cancer before surgery, the aim of our present study was to evaluate the oxidative stress by measuring the level of various biomarkers of this process such as the generation of superoxide anion radicals (O(2)(-·)), the amount of carbonyl groups and 3-nitrotyrosine in proteins or the amount of glutathione in blood platelets isolated from breast cancer patients after the surgery and after various phases of the chemotherapy in the presence of A. melanocarpa extract (Aronox) in vitro. We demonstrated in platelet proteins from patients with invasive breast cancer (after the surgery and after various phases of the chemotherapy) higher level of carbonyl groups than in control healthy group. The level of 3-nitrotyrosine in platelet proteins from patients with invasive breast cancer was also significantly higher than in healthy subject group. We observed an increase of other biomarkers of oxidative stress such as O(2)(-·) and a decrease of GSH in platelets from patients with breast cancer (after the surgery and after various phases of the chemotherapy) compared to the healthy group. In model system in vitro our results showed that the commercial extract from berries of A. melanocarpa due to antioxidant action, significantly reduced the oxidative/nitrative stress in platelets from patients with invasive breast cancer caused by the surgery and various phases of the chemotherapy.

    Despite the increasing use of stereotactic body radiation therapy (SBRT) and stereotactic radiation surgery (SRS) in recent years, the biological base of these high-dose hypo-fractionated radiotherapy modalities has been elusive. Given that most human tumors contain radioresistant hypoxic tumor cells, the radiobiological principles for the conventional multiple-fractionated radiotherapy cannot account for the high efficacy of SBRT and SRS. Recent emerging evidence strongly indicates that SBRT and SRS not only directly kill tumor cells, but also destroy the tumor vascular beds, thereby deteriorating intratumor microenvironment leading to indirect tumor cell death. Furthermore, indications are that the massive release of tumor antigens from the tumor cells directly and indirectly killed by SBRT and SRS stimulate anti-tumor immunity, thereby suppressing recurrence and metastatic tumor growth. The reoxygenation, repair, repopulation, and redistribution, which are important components in the response of tumors to conventional fractionated radiotherapy, play relatively little role in SBRT and SRS. The linear-quadratic model, which accounts for only direct cell death has been suggested to overestimate the cell death by high dose per fraction irradiation. However, the model may in some clinical cases incidentally do not overestimate total cell death because high-dose irradiation causes additional cell death through indirect mechanisms. For the improvement of the efficacy of SBRT and SRS, further investigation is warranted to gain detailed insights into the mechanisms underlying the SBRT and SRS.

    The bridge breakage fusion cycle is a chromosomal instability mechanism responsible for genomic changes. Radiation bystander effects induce genomic instability; however, the mechanism driving this instability is unknown. We examined if radiation and chemotherapy bystander effects induce early genomic instability events such as telomere shortening and bridge formation using a human colon cancer explant model. We assessed telomere lengths, bridge formations, mitochondrial membrane potential and levels of reactive oxygen species in bystander cells exposed to medium from irradiated and chemotherapy-treated explant tissues. Bystander cells exposed to media from 2 Gy, 5 Gy, FOLFOX treated tumor and matching normal tissue showed a significant reduction in telomere lengths (all p values <0.018) and an increase in bridge formations (all p values <0.017) compared to bystander cells treated with media from unirradiated tissue (0 Gy) at 24 h. There was no significant difference between 2 Gy and 5 Gy treatments, or between effects elicited by tumor versus matched normal tissue. Bystander cells exposed to media from 2 Gy irradiated tumor tissue showed significant depolarisation of the mitochondrial membrane potential (p = 0.012) and an increase in reactive oxygen species levels. We also used bystander cells overexpressing a mitochondrial antioxidant manganese superoxide dismutase (MnSOD) to examine if this antioxidant could rescue the mitochondrial changes and subsequently influence nuclear instability events. In MnSOD cells, ROS levels were reduced (p = 0.02) and mitochondrial membrane potential increased (p = 0.04). These events were coupled with a decrease in percentage of cells with anaphase bridges and a decrease in the number of cells undergoing telomere length shortening (p values 0.01 and 0.028 respectively). We demonstrate that radiation and chemotherapy bystander responses induce early genomic instability coupled with defects in mitochondrial function. Restoring

    Spinal intramedullary tuberculoma (SIT) is a rare manifestation of neurotuberculosis. Concurrent SIT and intracranial tuberculoma are further unusual. Most of these tuberculomas respond completely to medical therapy, and surgical excision is seldom required. In this report, we describe a 17-year-old boy who developed cervical intramedullary tuberculoma at C3-C6 level with a concurrent lesion involving the right cerebellar hemisphere while on treatment for tubercular meningitis. This patient had paradoxical increase in size of the cervical lesion even though the cerebellar lesion showed regression in size. In this article, we discuss the paradoxical response to anti-tubercular therapy in central nervous system tuberculosis, possible causes of nonresolution of tuberculoma on medical therapy and evaluate the role of surgery in these cases.

    Full Text Available Abstract Background Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC is a promising treatment for patients with peritoneal carcinomatosis (PC. Our objective was to identify new prognostic factors in patients with PC from colorectal cancer treated with this procedure. Methods All patients with PC from colorectal cancer treated by HIPEC from January 2000 to December 2007 were prospectively included. The tumor extension was assessed by the Peritoneal Cancer Index (PCI and the residual disease was recorded using the completeness cytoreductive score (CCs. All clinical and treatment data were computed in univariate and multivariable analyses using survival as primary end point. Results We carried out 51 complete procedures in 49 consecutive patients. The mean PCI was 10. The allocation of CCs was: CC-0 = 37, CC-1 = 14. The five-year overall and progression-free survival rate were 40% and 20%, respectively.

    Purpose: The safety and efficacy of skin-sparing mastectomy (SSM) with immediate reconstruction (IR) in patients with locally advanced breast cancer are unclear. The purpose of this study is to compare the outcomes of women with noninflammatory Stage III SSM with IR vs. non-SSM-treated women who underwent neoadjuvant chemotherapy and adjuvant radiation therapy (XRT). Methods and Materials: Between October 1997 and March 2010, 100 consecutive patients (40 SSM with IR vs. 60 non-SSM) with Stage III breast cancer received anthracycline- and/or taxane-based neoadjuvant chemotherapy, mastectomy, and adjuvant XRT. Clinical stage (SSM with IR vs. for non-SSM) was IIIA (75% vs. 67%), IIIB (8% vs. 18%), and IIIC (8% vs. 8%). Tumors greater than 5 cm were found in 74% vs. 69%; 97% of patients in both groups were clinically node positive; and 8% vs. 18% had T4b disease. Results: The time from initial biopsy to XRT was prolonged for SSM-IR patients (274 vs. 254 days, p = 0.04), and there was a trend toward XRT delay of more than 8 weeks (52% vs. 31%, p = 0.07) after surgery. The rate of complications requiring surgical intervention was higher in the SSM-IR group (37.5% vs. 5%, p < 0.001). The 2-year actuarial locoregional control, breast cancer-specific survival, and overall survival rates for SSM with IR vs. non-SSM were 94.7% vs. 97.4%, 91.5% vs. 86.3%, and 87.4% vs. 84.8%, respectively (p = not significant). Conclusions: In our small study with limited follow-up, SSM with IR prolonged overall cancer treatment time and trended toward delaying XRT but did not impair oncologic outcomes. Complication rates were significantly higher in this group. Longer follow-up is needed.

    Purpose: To evaluate the treatment outcome and efficacy of regional lymph node irradiation after neoadjuvant chemotherapy (NCT) and surgery in positron emission tomography (PET)-positive clinical N3 (cN3) breast cancer patients. Methods and Materials: A total of 55 patients with ipsilateral infraclavicular (ICL), internal mammary (IMN), or supraclavicular (SCL) lymph node involvement in the absence of distant metastases, as revealed by an initial PET scan, were retrospectively analyzed. The clinical nodal stage at diagnosis (2002 AJCC) was cN3a in 14 patients (26%), cN3b in 12 patients (22%), and cN3c in 29 patients (53%). All patients were treated with NCT, followed by mastectomy or breast-conserving surgery and subsequent radiotherapy (RT) with curative intent. Results: At the median follow-up of 38 months (range, 9-80 months), 20 patients (36%) had developed treatment failures, including distant metastases either alone or combined with locoregional recurrences that included one ipsilateral breast recurrence (IBR), six regional failures (RF), and one case of combined IBR and RF. Only 3 patients (5.5%) exhibited treatment failure at the initial PET-positive clinical N3 lymph node. The 5-year locoregional relapse-free survival, disease-free survival (DFS), and overall survival rates were 80%, 60%, and 79%, respectively. RT delivered to PET-positive IMN regions in cN3b patients and at higher doses ({>=}55 Gy) to SCL regions in cN3c patients was not associated with improved 5-year IMN/SCL relapse-free survival or DFS. Conclusion: NCT followed by surgery and RT, including the regional lymph nodes, resulted in excellent locoregional control for patients with PET-positive cN3 breast cancer. The primary treatment failure in this group was due to distant metastasis rather than RF. Neither higher-dose RT directed at PET-positive SCL nodes nor coverage of PET-positive IMN nodes was associated with additional gains in locoregional control or DFS.

    Cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) has been considered as a promising treatment modality for gastric cancer with peritoneal carcinomatosis (PC). However, there have also been many debates regarding the efficacy and safety of this new approach. Results from experimental animal model study could help provide reliable information. This study was to investigate the safety and efficacy of CRS + HIPEC to treat gastric cancer with PC in a rabbit model. VX2 tumor cells were injected into the gastric submucosa of 42 male New Zealand rabbits using a laparotomic implantation technique, to construct rabbit model of gastric cancer with PC. The rabbits were randomized into control group (n = 14), CRS alone group (n = 14) and CRS + HIPEC group (n = 14). The control group was observed for natural course of disease progression. Treatments were started on day 9 after tumor cells inoculation, including maximal removal of tumor nodules in CRS alone group, and maximal CRS plus heperthermic intraperitoneal chemoperfusion with docetaxel (10 mg/rabbit) and carboplatin (40 mg/rabbit) at 42.0 ± 0.5°C for 30 min in CRS + HIPEC group. The primary endpoint was overall survival (OS). The secondary endpoints were body weight, biochemistry, major organ functions and serious adverse events (SAE). Rabbit model of gastric cancer with PC was successfully established in all animals. The clinicopathological features of the model were similar to human gastric PC. The median OS was 24.0 d (95% confidence interval 21.8 - 26.2 d ) in the control group, 25.0 d (95% CI 21.3 - 28.7 d ) in CRS group, and 40.0 d (95% CI 34.6 - 45.4 d ) in CRS + HIPEC group (P = 0.00, log rank test). Compared with CRS only or control group, CRS + HIPEC could extend the OS by at least 15 d (60%). At the baseline, on the day of surgery and on day 8 after surgery, the peripheral blood cells counts, liver and kidney functions, and biochemistry parameters were all comparable. SAE

    Full Text Available This article brings mathematical modeling to bear on the reconstruction of the natural history of prostate cancer and assessment of the effects of treatment on metastatic progression. We present a comprehensive, entirely mechanistic mathematical model of cancer progression accounting for primary tumor latency, shedding of metastases, their dormancy and growth at secondary sites. Parameters of the model were estimated from the following data collected from 12 prostate cancer patients: (1 age and volume of the primary tumor at presentation; and (2 volumes of detectable bone metastases surveyed at a later time. This allowed us to estimate, for each patient, the age at cancer onset and inception of the first metastasis, the expected metastasis latency time and the rates of growth of the primary tumor and metastases before and after the start of treatment. We found that for all patients: (1 inception of the first metastasis occurred when the primary tumor was undetectable; (2 inception of all or most of the surveyed metastases occurred before the start of treatment; (3 the rate of metastasis shedding is essentially constant in time regardless of the size of the primary tumor and so it is only marginally affected by treatment; and most importantly, (4 surgery, chemotherapy and possibly radiation bring about a dramatic increase (by dozens or hundred times for most patients in the average rate of growth of metastases. Our analysis supports the notion of metastasis dormancy and the existence of prostate cancer stem cells. The model is applicable to all metastatic solid cancers, and our conclusions agree well with the results of a similar analysis based on a simpler model applied to a case of metastatic breast cancer.

    Thirty-five patients with nonmetastatic squamous cell carcinoma of the esophagus were treated with chemotherapy (5-fluorouracil, cisplatin) and concomitant split-course radiation therapy. All of the patients presented with dysphagia. Treatment consisted of two courses of chemotherapy with 5-FU (1 g/m2/day in continuous infusion for 5 days (days 1 to 5 and days 29 to 33) ) and cisplatin (70 mg/m2 intravenous bolus at days 2 and 30). Radiation therapy was concomitant in two courses delivering 20 Gy in 5 days (days 1 to 5 and days 29 to 33). On the first day of treatment, endoscopic peroral dilation or Nd-YAG laser therapy was usually carried out. At the end of the treatment, all of the patients were capable of oral nutrition. Histoendoscopic confirmation was made 8 weeks after the beginning of the therapy. Twenty-five of the 35 patients had a complete response with negative biopsy findings. There was only one serious complication (fatal myelosuppression) in the only patient who received more than two courses of chemotherapy. Sixteen patients died and 19 were still alive at 3 to 42 months after the beginning of treatment. Overall median survival for the 35 patients is 17 months. Actuarial survival was 55 +/- 18% at 1 year and 41 +/- 21% at 2 years. The median survival of the Stage I and II patients is 28 months. These results confirm that concomitant chemoradiotherapy is capable of producing a very high histoendoscopic complete response rate and improved 1-year and 2-year survival. The use of concentrated split-course radiotherapy enabled the authors to reduce the total length of the treatment to two periods of 5 days, with results that are similar to previous studies using classic radiotherapy for a 5-week to 7-week period.

    Radiotherapy alone or in combination with chemotherapy and/or surgery is a well-known radical treatment for head and neck cancer patients. Nevertheless acute side effects (such as moist desquamation, skin erythema, loss of taste, mucositis etc.) and in particular late toxicities (osteoradionecrosis, xerostomia, trismus, radiation caries etc.) are often debilitating and underestimated. A multidisciplinary group of head and neck cancer specialists from Italy met in Milan with the aim of reaching a consensus on a clinical definition and management of these toxicities. The Delphi Appropriateness method was used for this consensus and external experts evaluated the conclusions. The paper contains 20 clusters of statements about the clinical definition and management of stomatological issues that reached consensus, and offers a review of the literature about these topics. The review was split into two parts: the first part dealt with dental pathologies and osteo-radionecrosis (10 clusters of statements), whereas this second part deals with trismus and xerostomia (10 clusters of statements).

    Full Text Available BACKGROUND: To evaluate the contribution of chemotherapy for patients with locoregionally advanced nasopharyngeal carcinoma (NPC treated by intensity modulated radiotherapy (IMRT and to identify the optimal combination treatment strategy. PATIENTS AND METHODS: Between 2006 and 2010, 276 patients with stage II-IVb NPC were treated by IMRT alone or IMRT plus chemotherapy. Cisplatin-based chemotherapy included neoadjuvant or concurrent, or neoadjuvant plus concurrent protocols. The IMRT alone and chemoradiotherapy groups were well-matched for prognostic factors, except N stage, with more advanced NPC in the chemoradiotherapy arm. RESULTS: With a mean follow-up of 33.8 months, the 3-year actuarial rates of overall survival (OS, metastasis-free survival (MFS, relapse-free survival (RFS, and disease-free survival (DFS were 90.3%, 84.2%, 80.3%, and 69.2% for all of the patients, respectively. Compared with the IMRT alone arm, patients treated by concurrent chemoradiotherapy had a significantly better DFS (HR = 2.64; 95% CI, 1.12-6.22; P = 0.03, patients with neoadjuvant-concurrent chemoradiotherapy had a significant improvement in RFS and DFS (HR = 4.03; 95% CI, 1.35-12.05; P = 0.01 and HR = 2.43; 95% CI, 1.09-5.44; P = 0.03, neoadjuvant chemoradiotherapy provided no significant benefit in OS, MFS, RFS, and DFS. Stage group and alcohol consumption were prognostic factors for OS and N stage was a significant predictor for DFS. CONCLUSIONS: Addition of concurrent or neoadjuvant-concurrent chemotherapy to IMRT is available to prolong RFS or DFS for locoregionally advanced NPC. Such work could be helpful to guide effective individualized therapy.

    Significant risk factors for recurrence of breast cancer after breast-conserving therapy, which has become a standard treatment for breast cancer, are positive surgical margins and the failure to perform radiation therapy. In this study, we evaluated the clinical significance of radiation therapy after primary surgery or breast recurrence. In 344 cases of breast-conserving surgery, disease recurred in 43 cases (12.5%), which were classified as follows: 17 cases of breast recurrence, 13 cases of breast and distant metastasis, and 13 cases of distant metastasis. Sixty-two patients (16.7%) received radiation therapy. A positive surgical margin and younger age were significant risk factors for breast recurrence in patients not receiving postoperative radiation therapy but not in patients receiving radiation therapy. Radiation therapy may be beneficial for younger patients with positive surgical margins. Furthermore, radiation therapy after recurrence was effective in the cases not treated with postoperative radiation but not in cases with inflammatory recurrence. Patients with breast recurrence alone had significantly higher survival rates than did patients with distant metastases regardless of breast recurrence. These findings suggest that the adaptation criteria of radiation therapy for local control must be clarified. (author)

    A case of treatment-related leukoencephalopathy is presented. A patient with breast cancer metastasis to the brain, liver, bone and distant lymph nodes was treated with whole brain radiation and docetaxcel. Eleven months after radiation, magnetic resonance imaging showed diffuse leukoencephalopathy. Twenty-two months after radiation, the patient had gait disturbance, parkinsonism, dementia and urinary incontinence. From this experience, stereotactic radiosurgery such as cyber knife and gamma knife therapy, representing a new modality for delivering intense focal radiation, should be come preferred techniques for treating patients with brain metastases, to avoid the potential cognitive side effects of fractionated whole-brain radiotherapy.

    Background Neoplasms of histiocytic and dendritic cell origin, including follicular dendritic cell sarcoma (FDCS), histiocytic sarcoma (HS) and interdigitating dendritic cell sarcoma (IDCS), are extremely rare, and data on their natural history and treatment outcomes are sparse. We evaluated the impact of surgery, radiation and systemic therapies on overall survival (OS). Methods We conducted a retrospective chart review of patients with FDCS, IDCS and HS treated at Memorial Sloan Kettering Cancer Center between 1995 and 2014. Results We identified 31, 15 and 7 patients with FDCS, HS and IDCS, respectively. Median age was 48.7, 42.3 and 58.8 years for FDCS, HS and IDCS, respectively. Only a slight disparity in gender distribution existed for FDCS and HS; however, IDCS predominantly affected males (6:1). The most common sites of presentation were abdomen and pelvis (42%), extremities (33%) and head and neck (57%) for FDCS, HS and IDCS, respectively. At diagnosis, 74%, 40% and 86% of patients presented with localised disease in FDCS, HS and IDCS, respectively. Patients with localised disease had significantly improved OS than those with metastatic disease in FDCS (P = 0.04) and IDCS (P = 0.014) but not in HS (P = 0.95). In FDCS and HS, adjuvant or neo-adjuvant therapy was not associated with improved OS compared with observation. In IDCS, surgery alone provided a 5-year overall survival rate of 71%. Conclusions Adjuvant or neo-adjuvant treatment in FDCS and HS did not affect OS. Patients with IDCS had an excellent outcome with surgery. In the metastatic setting, chemotherapy and small molecule inhibitors may provide benefit. PMID:26298731

    Purpose: The prognosis for children with central nervous system primitive neuroectodermal tumor (CNS-PNET) or pinealoblastoma is still unsatisfactory. Here we report the results of patients between 4 and 21 years of age with nonmetastatic CNS-PNET or pinealoblastoma diagnosed from January 2001 to December 2005 and treated in the prospective GPOH-trial P-HIT 2000-AB4. Methods and Materials: After surgery, children received hyperfractionated radiation therapy (36 Gy to the craniospinal axis, 68 Gy to the tumor region, and 72 Gy to any residual tumor, fractionated at 2 × 1 Gy per day 5 days per week) accompanied by weekly intravenous administration of vincristine and followed by 8 cycles of maintenance chemotherapy (lomustine, cisplatin, and vincristine). Results: Twenty-six patients (15 with CNS-PNET; 11 with pinealoblastoma) were included. Median age at diagnosis was 11.5 years old (range, 4.0-20.7 years). Gross total tumor resection was achieved in 6 and partial resection in 16 patients (indistinct, 4 patients). Median follow-up of the 15 surviving patients was 7.0 years (range, 5.2-10.0 years). The combined response rate to postoperative therapy was 17 of 20 (85%). Eleven of 26 patients (42%; 7 of 15 with CNS-PNET; 4 of 11 with pinealoblastoma) showed tumor progression or relapse at a median time of 1.3 years (range, 0.5-1.9 years). Five-year progression-free and overall survival rates (±standard error [SE]) were each 58% (±10%) for the entire cohort: CNS-PNET was 53% (±13); pinealoblastoma was 64% (±15%; P=.524 and P=.627, respectively). Conclusions: Postoperative hyperfractionated radiation therapy with local dose escalation followed by maintenance chemotherapy was feasible without major acute toxicity. Survival rates are comparable to those of a few other recent studies but superior to those of most other series, including the previous trial, HIT 1991.

    Meningeal hemangiopericytoma (HPC) is an uncommon dura-based tumor and can recur not only locally but also distantly in the neural axis or extraneural sites. We report our experience of radiation therapy, one preoperative and one elective postoperative, in two patients with meningeal HPC and reviewed the role of radiation therapy. A 41-year-old man (Case 1) presented with a 3-month history of headache and right hemiparesis. The mass was nearly unresectable at the first and second operation and diagnosed as meningeal HPC. Preoperative radiation therapy was given with a total dose of 55.8 Gy/31 fractions to the large residual mass of left frontoparietal area. Follow-up computerized tomography (CT) showed marked regression of tumor after radiation therapy. The third operation was performed to remove the residual tumor at 6 months after the radiation therapy and a 2 x 2 cm sized tumor was encountered. The mass was totally removed. The serial follow-up CT showed no evidence of recurrence and he is alive without distant metastasis for 4 years and 10 months after the first operation. A 45-year-old woman (Case 2) presented with suddenly developed headache and visual impairment. Tumor mass occupying right frontal lobe was removed with the preoperative diagnosis of meningioma. It was totally removed with attached sagittal sinus and diagnosed as meningeal HPC. Elective postoperative radiation therapy was performed to reduce local recurrence with a total dose of 54 Gy/30 fractions to the involved area of right frontal lobe. She is alive for 5 years maintaining normal activity without local recurrence and distant metastasis.

    Author`s experience of surgery for radiation colitis was examined and discussed on the primary disease, radiation dose, major symptoms, surgical techniques, results and post-operative complication. Patients were 1 male and 21 females of the average age of 59.5 y. The primary diseases were bladder cancer for the male and uterine cancer for the females. The radiation dose ranged from 35-120 Gy and was 63.4 Gy in a mean. The symptoms for surgery were 14 ileuses, 4 intestinal hemorrhages, 1 perforation and 3 burrows. Colostomy was performed for 18 cases; enterostomy, 2; anastomosis, 1; and enterectomy, 1, which resulted in improvement of symptoms in 5 cases, 0, 1 and 1, respectively. The author concluded that radiation colitis should be treated preventively. (K.H.)

    Full Text Available OBJECTIVE: To find a biological effect by means of detection of the thyroid profile in research personnel, and a physical effect through radiation detection plates type Durr. METHODS: Five medical residents (four of first year and one of second were submitted to the study of the basal thyroid profile, and annually after a year of radiation exposure. In two of them five plates of Durr type were placed by surgery at different body parts and 20 separate surgeries, using fluoroscopy, a total of 200 plates exposed. RESULTS: Three residents had decreased thyroid-stimulating hormone and two had a significant increase. Ninety-one plates were exposed, most of which corresponds to the neck (thyroid. CONCLUSION: Biological and physical changes were observed that require us to realize and implement protective measures against radiation, at least in the neck, because the thyroid is susceptible to radiation.

  1. Serum Biomarkers for the Detection of Cardiac Toxicity after Chemotherapy and Radiation Therapy in Breast Cancer Patients

    Full Text Available Multi-modality cancer treatments that include chemotherapy, radiation therapy, and targeted agents are highly effective therapies. Their use, especially in combination, is limited by the risk of significant cardiac toxicity. The current paradigm for minimizing cardiac morbidity, based on serial cardiac function monitoring, is suboptimal. An alternative approach based on biomarker testing, has emerged as a promising adjunct and a potential substitute to routine echocardiography. Biomarkers, most prominently cardiac troponins and natriuretic peptides, have been evaluated for their ability to describe the risk of potential cardiac dysfunction in clinically asymptomatic patients. Early rises in cardiac troponin concentrations have consistently predicted the risk and severity of significant cardiac events in patients treated with anthracycline-based chemotherapy. Biomarkers represent a novel, efficient, and robust clinical decision tool for the management of cancer therapy-induced cardiotoxicity. This article aims to review the clinical evidence that supports the use of established biomarkers such as cardiac troponins and natriuretic peptides, as well as emerging data on proposed biomarkers.

    The purpose of this study was to evaluate treatment results in terms of the survival and failure patterns subsequent to radiation therapy in recurrent cervical cancer, following primary surgery. Between January 1990 and December 1999, 27 patients, with recurrent cervical cancer following primary surgery, were subsequently treated with radiation in the Department of Radiation Oncology, at the Keimyung University Dongsan Medical Center. Their median age was 48, ranging from 31 to 70 years old. With regard to the initial FIGO stage on presentation, 20 and 7 patients were stages I and II, respectively. Twenty three patients had squamous ceH carcinomas and 4 had adenocarcinomas. The time interval from the primary surgery to the recurrence ranged from 2 to 90 months with a median of 29 months. The recurrent sites were the vaginal cuff alone, the pelvic cavity and combined recurrence in 14, 9 and 4 patients, respectively. Radiation was performed, with external and vaginal intracavitary radiation in 13 patients, external radiation alone in 13 and vaginal intracavitary radiation alone in another one. The median follow-up period was 55 months, ranging from 6 to 128 months. The five year disease free survival (5y DFS) and five year overall survival (5y OS) rates were 68.2 and 71.9%, respectively. There was a marginal statistically significant difference in the 5y DFS in relation to the recurrent site (5y DFS, 85.7% in vaginal cuff recurrence alone, 53.3% in pelvic cavity recurrence, p=0.09). There was no difference in the survival according to the time interval between the primary surgery and a recurrence. There was only a 7% local failure rate in the patients with a vaginal cuff recurrence. The major failure patterns were local failure in the patients with pelvic cavity recurrence, and distant failure in the patients with a combined recurrence. There were no complications above grade 3 after the radiation therapy. Radiation therapy was safe and effective treatment for a

    Objectives High-grade soft-tissue sarcoma (STS) has a poor prognosis. The goal of this study was to review treatment outcomes of patients with high-grade STS treated with interdigitated neoadjuvant chemotherapy (CT) and radiation at our institution. Materials and Methods Patients with high-grade STS (1997 to 2010) were planned for treatment with 3 cycles of neoadjuvant CT, interdigitated preoperative radiation therapy (44 Gy administered in split courses with a potential 16 Gy postoperative boost), and 3 cycles of postoperative CT. Cancer control outcomes at 3 years were analyzed. Results Sixteen patients with high-grade STS were evaluated. Median age was 53 years, the median longest tumor diameter was 14.6 cm, and median follow-up was 33 months. All 16 patients received 2 or 3 cycles of neoadjuvant CT and all patients completed neoadjuvant RT. The estimated 3-year rate for local control was 100%, disease-free survival 62.5%, and overall survival 73.4%. Conclusions Patients with high-grade STS treated with interdigitated neoadjuvant CT and radiation before surgical resection had excellent rates of local control, along with disease-free survival and overall survival similar to previously published reports. This combined-modality approach continues to have a role in the treatment of patients with high-grade STS. PMID:25268069

    A rare case of large germinoma in the basal ganglia is reported which was effectively treated by intracarotid chemotherapy with ACNU following osmotic blood-brain barrier disruption using 20 % mannitol and radiation therapy. A 19-year-old man displayed slowly progressive right hemiparesis, motor aphasia and predementia on admission. Plain CT demonstrated a tumor which had a slightly high density with intratumoral calcification and a small cyst, and slight to moderate enhancement was observed following intravenous injection of contrast medium, but there was no unilateral ventricular enlargement. Cerebral angiography revealed hypervascular tumor staining with early draining veins. After biopsy, and as a result of intracarotid chemotherapy with ACNU following osmotic blood-brain barrier disruption and radiation therapy, the tumor decreased rapidly to about 20 % of its original mass. After discharge, tumor progression was observed. However, the enlarged tumor mass almost disappeared (except for calcification) on CT with clinical improvement in response to intracarotid chemotherapy with ACNU following 20 % mannitol.

    Objective: The aim of this study was to evaluate the efficacy, complications and cosmetic results of three-dimensional conformal radiation therapy for early breast cancer after conservative surgery. Methods: Among 80 patients, 44 were treated by modified radical mastectomy followed by adjuvant radiotherapy (modified radical mastectomy, MMT), 36 were treated with breast conservative surgery with adjuvant irradiation [breast-conservation therapy (BCT)]. Tangential fields were used to deliver 6 MV X-ray beams to a total dose of 50 Gy. Another 16 Gy was added to the tumor bed with 6-9 MeV electron beams for BCT. Results: In MMT group, the local control, metastasis-free and death were 41, 41 and 1 respectively; in BCT group, the local control, metastasis-free and death were 35, 35 and 0. The difference of the above two indicators between the two groups showeed no statistical insignificance (P > 0. 05). In MMT group, 32 patients suffer radiation dermatitis above 2-level, 12 patients suffer radiation pneumonia, and 10 patients suffer edema of illness-side upper extremity; in BCT group, the above indicators were only 6, 2 and 1 respectively. Three months, six months and one year after radiation therapy, 90%, 92% and 95% patients were assessed as excellence in fine cosmetic state in BCT group. Conclusion: The effects of threedimensional conformal radiation therapy after conservative surgery are the same as that of modified radical mastectomy, while the former has better cosmetic results and lower radiation therapy induced complications.

    Purpose: The development of breast cancer-related lymphedema (LE) is closely related to the number of dissected axillary lymph nodes (N-ALNs), chemotherapy, and radiation therapy. In this study, we attempted to estimate the risk of LE based on combinations of these treatment-related factors. Methods and Materials: A total of 772 patients with breast cancer, who underwent primary surgery with axillary lymph node dissection from 2004 to 2009, were retrospectively analyzed. Adjuvant chemotherapy (ACT) was performed in 677 patients (88%). Among patients who received radiation therapy (n=675), 274 (35%) received supraclavicular radiation therapy (SCRT). Results: At a median follow-up of 5.1 years (range, 3.0-8.3 years), 127 patients had developed LE. The overall 5-year cumulative incidence of LE was 17%. Among the 127 affected patients, LE occurred within 2 years after surgery in 97 (76%) and within 3 years in 115 (91%) patients. Multivariate analysis showed that N-ALN (hazard ratio [HR], 2.81; P<.001), ACT (HR, 4.14; P=.048), and SCRT (HR, 3.24; P<.001) were independent risk factors for LE. The total number of risk factors correlated well with the incidence of LE. Patients with no risk or 1 risk factor showed a significantly lower 5-year probability of LE (3%) than patients with 2 (19%) or 3 risk factors (38%) (P<.001). Conclusions: The risk factors associated with LE were N-ALN, ACT, and SCRT. A simple model using combinations of these factors may help clinicians predict the risk of LE.

    Full Text Available Peritoneal carcinomatosis (PC is a difficult clinical challenge in colorectal cancer (CRC because conventional treatment modalities could not produce significant survival benefit, which highlights the acute need for new treatment strategies. Our previous case-control study demonstrated the potential survival advantage of cytoreductive surgery (CRS plus hyperthermic intraperitoneal chemotherapy (HIPEC over CRS alone. This phase II study was to further investigate the efficacy and adverse events of CRS+HIPEC for Chinese patients with CRC PC.A total of 60 consecutive CRC PC patients underwent 63 procedures consisting of CRS+HIPEC and postoperative chemotherapy, all by a designated team focusing on this combined treatment modality. All the clinico-pathological information was systematically integrated into a prospective database. The primary end point was disease-specific overall survival (OS, and the secondary end points were perioperative safety profiles.By the most recent database update, the median follow-up was 29.9 (range 3.5-108.9 months. The peritoneal cancer index (PCI ≤20 was in 47.0% of patients, complete cytoreductive surgery (CC0-1 was performed in 53.0% of patients. The median OS was 16.0 (95% confidence interval [CI] 12.2-19.8 months, and the 1-, 2-, 3-, and 5-year survival rates were 70.5%, 34.2%, 22.0% and 22.0%, respectively. Mortality and grades 3 to 5 morbidity rates in postoperative 30 days were 0.0% and 30.2%, respectively. Univariate analysis identified 3 parameters with significant effects on OS: PCI ≤20, CC0-1 and adjuvant chemotherapy over 6 cycles. On multivariate analysis, however, only CC0-1 and adjuvant chemotherapy ≥6 cycles were found to be independent factors for OS benefit.CRS+HIPEC at a specialized treatment center could improve OS for selected CRC PC patients from China, with acceptable perioperative safety.

    Purpose Describe frequencies and risk factors of altered oral health and odontogenesis in childhood cancer survivors. Patients and Methods 9308 survivors, diagnosed between 1970–1986, and 2951 siblings from Childhood Cancer Survivor Study completed a survey containing oral-dental health information. We analyzed treatment impact, socioeconomic data and patient demographics on dental outcomes using univariate and multivariate logistic regression models to estimate odds ratios (OR). Results In multivariate analysis, survivors more likely reported microdontia (OR 3.0, 95% confidence interval [CI] 2.4–3.8), hypodontia (OR 1.7, 95% CI 1.4–2.0), root abnormalities (OR 3.0, 95% CI 2.2–4.0), abnormal enamel (OR 2.4, 95% CI 2.0–2.9), teeth loss ≥6 (OR 2.6, 95% CI 1.9–3.6), severe gingivitis (OR 1.2, 95% CI 1.0–1.5), xerostomia (OR 9.7, 95% CI 4.8–19.7). Controlling for chemotherapy and socio-economic factors, radiation exposure of ≥20Gy to dentition was significantly associated with increased risk of ≥1 dental abnormality. Dose-dependent alkylating agent therapy significantly increased risk ≥1 anatomic/developmental dental abnormalities in survivors diagnosed <5 years of age (OR 1.7, 2.7, 3.3 for alkylating agent score of 1, 2, 3, respectively). Conclusion Radiation and chemotherapy are independent risk factors for adverse oral-dental sequelae among childhood cancer survivors. Patients receiving alkylating agents at < 5 years should be closely monitored. PMID:19834960

    Full Text Available Background: Breast cancer is the most common cancer in urban India, but no study has been carried out on psychosocial disorders in breast cancer patients. Aims: The present study has been undertaken to evaluate behavioural and psychosocial impacts before and after treatment of women with breast cancer. Settings and Design: The study was carried out in a reputed hospital in Delhi. Patients and Methods: A total of 97 breast cancer patients matched for age and economic status were divided into group A (66 and group B (31 on the basis of treatment modalities offered to the patient. These women were interviewed, before and after the treatment, and the observations were recorded in a pre-tested structured questionnaire. Statistical Analysis: Chi-square test and Fisher′s exact test were used to calculate statistical significance. Results: Although the extent of sociobehavioral disorders were higher in patients on postoperative adjuvant chemotherapy and radiotherapy when compared with those on postoperative adjuvant chemotherapy alone, the difference was, however, not statistically significant. Psychological reactions were observed in 31% of patients but after intervention, 65% showed adjustment within 4 to 12 weeks, whereas the rest showed late adjustments. Conclusions: Breast disfigurement and sexuality were found to be least important, but psychological and social support appears to significantly influence the treatment outcome and rehabilitation of breast cancer patients in India.

  10. Chemoradiation for Ductal Pancreatic Carcinoma: Principles of Combining Chemotherapy with Radiation, Definition of Target Volume and Radiation Dose

    2005-05-01

    Full Text Available Review of the role of chemoradiotherapy in the treatment of locally advanced pancreatic cancer with a specific focus on the technical feasibility and the integration of chemoradiotherapy into multimodal treatment concepts. Combined chemoradiotherapy of pancreatic cancer is a safe treatment with an acceptable profile of side effects when applied with modern planning and radiation techniques as well as considering tissue tolerance. Conventionally fractionated radiation regimens with total doses of 45-50 Gy and small-volume boost radiation with 5.4 Gy have found the greatest acceptance. Locoregional lymphatic drainage should be included in the planning of target volumes because the risk of tumor involvement and local or loco-regional recurrence is high. Up to now, 5-fluorouracil has been considered the "standard" agent for concurrent chemoradiotherapy. The role of gemcitabine given concurrently with radiation has not yet been defined, since high local efficacy may also be accompanied by enhanced toxicities. In addition, no dose or administration form has been determined to be "standard" up to now. The focus of presently ongoing research is to define an effective and feasible regimen of concurrent chemoradiotherapy. While preliminary results indicate promising results using gemcitabine-based chemoradiotherapy, reliable data derived from mature phase III trials are greatly needed. Intensity-modulated radiotherapy has been developed to improve target-specific radiation and to reduce organ toxicity. Its clinical relevance still needs to be defined.

    It is estimated that 37% of the U.S. population is obese. It is unknown how obesity influences the operative and survival outcomes of cytoreductive surgery (CRS)/hyperthermic intraperitoneal chemotherapy (HIPEC) procedures. A retrospective analysis of a prospective database of 1,000 procedures was performed. Type of malignancy, performance status, resection status, hospital and intensive care unit stay, comorbidities, morbidity, mortality, and survival were reviewed. A total of 246 patients with body mass index (BMI) of >30 kg/m(2) underwent 272 CRS/HIPEC procedures. Ninety-five (38.6%) were severely obese (BMI > 35 kg/m(2)). A total of 135 (49.6%) procedures were performed for appendiceal and 60 (22.1%) for colon cancer. Median follow-up was 52 months. Both major and minor morbidity were similar for obese and non-obese patients. The 30-day mortality rates for obese and non-obese patients were 1.5 and 2.5%, respectively. Median intensive care unit and hospital stay were 1 and 9 days, regardless of BMI. The 30-day readmission rate was similar between obese and non-obese patients (24.8 vs. 19.4%, p = 0.11). Median survival for low-grade appendiceal cancer (LGA) was 76 months for obese patients and 107 months for non-obese patients (p = 0.32). Survival was worse for severely obese patients (median survival 54 months) versus non-obese patients with LGA (p = 0.04). Survival was similar for obese and non-obese patients with peritoneal surface disease (PSD) from colon cancer or high-grade appendiceal cancer. Obesity does not influence postoperative morbidity or mortality of patients with PSD, regardless of primary tumor. Severe obesity is associated with decreased long-term survival only in patients with LGA primary disease; however, application of CRS/HIPEC still offers meaningful prolongation of life. Obesity should not be considered a contraindication for CRS/HIPEC procedures.

    The aim of this study was to investigate the therapeutic response and toxicity of intensity-modulated radiation therapy (IMRT) or conventional radiotherapy (c-RT) as adjuvant therapy in patients with pelvic locoregional recurrence of cervical cancer after radical surgery. This retrospective study included 161 patients with unresectable pelvic locoregional recurrence of cervical cancer after radical surgery between March 2003 and May 2012. All patients were initially diagnosed with International Federation of Gynecology and Obstetrics stage IB-IIA cervical cancer and received radical hysterectomy and pelvic lymphadenectomy. A total of 82 patients were treated with c-RT, whereas the remaining 79 patients underwent IMRT. Intracavitary brachytherapy and concurrent chemotherapy were performed during external irradiation. The mean dose delivered to the planning target volume was significantly higher in the IMRT group than in the c-RT group (61.8 vs 50.3 Gy, P = 0.029). Intensity-modulated radiation therapy plans yielded better dose sparing of small bowel, bladder, and rectum than did c-RT (P cervical cancer after radical surgery. The acute and chronic toxicities were acceptable, and the adjacent organs at risk were well protected.

    Background: In the era of preoperative chemoradiotherapy (CRT) and total mesorectal excision (TME), the development of distant metastases is the predominant mode of failure in rectal cancer patients today. Integrating more effective systemic therapy into combined modality programs is the challenge. The question that needs to be addressed is how and when to apply systemic treatment with adequate dose and intensity. Material and Methods: This review article focuses on phase II-III trials designed to improve 5-fluorouracil (5-FU)-based combined modality treatment for rectal cancer patients through the inclusion of concurrent, adjuvant or, most recently, induction combination chemotherapy. Computerized bibliographic searches of PubMed were supplemented with hand searches of reference lists and abstracts of ASCO/ASTRO/ESTRO meetings. Results: After preoperative CRT and surgical resection, approximately one third of patients do not receive adjuvant chemotherapy, mainly due to surgical complications, patients' refusal, or investigator's discretion. In order to be able to apply chemotherapy with sufficient dose and intensity, an innovative approach is to deliver systemic therapy prior to preoperative CRT rather than adjuvant chemotherapy. Emerging evidence from several phase II trials and, recently, randomized phase II trials indicate that induction chemotherapy is feasible, does not compromise CRT or surgical resection, and enables the delivery of chemotherapy in adequate dose and intensity. Although this approach did not increase local efficacy in recent trials (e.g., pathological complete response rates, tumor regression, R0 resection rates, local control), it may help to improve control of distant disease. Conclusion: Whether this improvement in applicability and dose density of chemotherapy will ultimately translate into improved disease-free survival will have to be tested in a larger phase III trial.

    A combination of S-1, a newly developed oral 5-fluorouracil derivative, and cisplatin is reported to show anti-tumour activity against advanced non-small cell lung cancer (NSCLC). Because S-1 shows synergistic effects with radiation, we conducted a phase I study to evaluate the maximum tolerated doses (MTDs), recommended doses (RDs), and dose-limiting toxicities (DLTs) of cisplatin and S-1 when combined with concurrent thoracic radiation (total dose of 60 Gy with 2 Gy per daily fraction) in patients with locally advanced NSCLC. Chemotherapy consisted of two 4-week cycles of cisplatin administered on days 1 and 8, and S-1 administered on days 1-14. S-1/cisplatin dosages (mg/m(2)/day) were escalated as follows: 60/30, 60/40, 70/40, 80/40 and 80/50. Twenty-two previously untreated patients were enrolled. The MTDs and RDs for S-1/cisplatin were 80/50 and 80/40, respectively. DLTs included febrile neutropaenia, thrombocytopaenia, bacterial pneumonia and delayed second cycle of chemotherapy. No patient experienced radiation pneumonitis>grade 2 and only one patient experienced grade 3 radiation oesophagitis. The overall response rate was 86.4% with a median survival time of 24.4 months. These results indicate that combination cisplatin-S-1 chemotherapy with concurrent thoracic radiation would be a feasible treatment option and a phase II study is currently under way.

    Full Text Available We report the case of a 60-year-old male who was diagnosed with gastric cancer. Upper gastrointestinal endoscopy indicated advanced cancer in the posterior wall of the gastric body. Biopsy revealed poorly differentiated adenocarcinoma.

The involvement of the PAN extended from the celiac axis to the caudal area of the inferior mesenteric artery [cT3N3aH0P0M1(LYM, stage IV]. Systemic chemotherapy was initiated. After 3 courses of S-1 plus cisplatin combination chemotherapy, the primary lesion and the enlarged lymph nodes revealed marked regression except for a minute residual lesion in the lymph nodes. Upon obtaining informed consent, open distal gastrectomy, D2 lymphadenectomy with PAN dissection, and Roux-en-Y reconstruction were performed. The patient was discharged from the hospital 35 days after the operation. Histopathological examination of the resected samples revealed malignant cells only in the PAN, not in the stomach or in the regional lymph nodes [ypT0N0M1(LYM, stage IV]. Currently, the patient is undergoing postoperative adjuvant chemotherapy with S-1 and has remained well without any recurrence after 6 months following surgery.

    We report the case of a 60-year-old male who was diagnosed with gastric cancer. Upper gastrointestinal endoscopy indicated advanced cancer in the posterior wall of the gastric body. Biopsy revealed poorly differentiated adenocarcinoma. Abdominal computed tomography demonstrated thickening of the gastric wall and enlargement of the regional lymph nodes and of the para-aortic lymph nodes (PAN). The involvement of the PAN extended from the celiac axis to the caudal area of the inferior mesenteric artery [cT3N3aH0P0M1(LYM), stage IV]. Systemic chemotherapy was initiated. After 3 courses of S-1 plus cisplatin combination chemotherapy, the primary lesion and the enlarged lymph nodes revealed marked regression except for a minute residual lesion in the lymph nodes. Upon obtaining informed consent, open distal gastrectomy, D2 lymphadenectomy with PAN dissection, and Roux-en-Y reconstruction were performed. The patient was discharged from the hospital 35 days after the operation. Histopathological examination of the resected samples revealed malignant cells only in the PAN, not in the stomach or in the regional lymph nodes [ypT0N0M1(LYM), stage IV]. Currently, the patient is undergoing postoperative adjuvant chemotherapy with S-1 and has remained well without any recurrence after 6 months following surgery. PMID:26351440

    Pathologic downstaging following chemotherapy for stage III-N2 NSCLC is a well-known positive prognostic indicator. However, the predictive factors for locoregional recurrence (LRR) in these patients are largely unknown. Between 1998 and 2008, 153 patients with clinically or pathologically staged III-N2 NSCLC from two cancer centers in the United States were treated with induction chemotherapy and surgery. All had pathologic N0-1 disease, and none received postoperative radiotherapy. LRR were defined as recurrence at the surgical site, lymph nodes (levels 1-14 including supraclavicular), or both. Median follow-up was 39.3 months. Pretreatment N2 status was confirmed pathologically (18.2 %) or by PET/CT (81.8 %). Overall, the 5-year LRR rate was 30.8 % (n = 38), with LRR being the first site of failure in 51 % (22/+99877943). Five-year overall survival for patients with LRR compared with those without was 21 versus 60.1 % (p recurrence (p = 0.021, HR 1.91, 95 % CI 1.1-3.3) but only trended for poorer survival (p = 0.123, HR 1.48, 95 % CI 0.9-2.44). LRR remains high in resected stage III-N2 NSCLC patients after induction chemotherapy and nodal downstaging, particularly in patients with persistent N1 disease.

    The objective of this study was to determine the frequency of recommendation of adjuvant chemotherapy by UK-based general veterinary practitioners (GVPs) for canine patients with high-grade mast cell tumours (HGMCTs), splenic haemangiosarcomas (SHSs) and appendicular osteosarcomas (AOSs); to determine which chemotherapeutic protocols are used by GVPs; and to evaluate reasons why chemotherapy may or may not be recommended postoperatively. An internet survey was created in 2013 using an online programme and was distributed to GVPs. Questions relating to the use of adjuvant chemotherapy for three tumours were selected. In total, 300 responses were generated. Surgery was seen as primary therapy by most GVPs for HGMCT (91 per cent) and SHS (88 per cent), but less frequently for AOS (59 per cent). Also, 90, 40 and 57 per cent of respondents recommended adjuvant chemotherapy for HGMCT, SHS and AOS, respectively. Of these, an appropriate chemotherapy protocol was not known by 25, 51 and 36 per cent of GVPs for HGMCT, SHS and AOS, respectively. From the GVPs not recommending chemotherapy, 29, 64 and 66 per cent did not believe chemotherapy to be efficacious for these tumours. The frequency of recommendation regarding postoperative chemotherapy is variable by tumour type. Reasons given why postoperative chemotherapy is not recommended also vary by tumour type.

    To examine the incidence of clinically important cataracts in relation to lens radiation doses between 0 and approximately 3 Gy to address risks at relatively low brief doses. Informed consent was obtained, and human subjects procedures were approved by the ethical committee at the Radiation Effects Research Foundation. Cataract surgery incidence was documented for 6066 atomic bomb survivors during 1986-2005. Sixteen risk factors for cataract, such as smoking, hypertension, and corticosteroid use, were not confounders of the radiation effect on the basis of Cox regression analysis. Radiation dose-response analyses were performed for cataract surgery incidence by using Poisson regression analysis, adjusting for demographic variables and diabetes mellitus, and results were expressed as the excess relative risk (ERR) and the excess absolute risk (EAR) (ie, measures of how much radiation multiplies [ERR] or adds to [EAR] the risk in the unexposed group). Of 6066 atomic bomb survivors, 1028 underwent a first cataract surgery during 1986-2005. The estimated threshold dose was 0.50 Gy (95% confidence interval [CI]: 0.10 Gy, 0.95 Gy) for the ERR model and 0.45 Gy (95% CI: 0.10 Gy, 1.05 Gy) for the EAR model. A linear-quadratic test for upward curvature did not show a significant quadratic effect for either the ERR or EAR model. The linear ERR model for a 70-year-old individual, exposed at age 20 years, showed a 0.32 (95% CI: 0.09, 0.53) [corrected] excess risk at 1 Gy. The ERR was highest for those who were young at exposure. These data indicate a radiation effect for vision-impairing cataracts at doses less than 1 Gy. The evidence suggests that dose standards for protection of the eye from brief radiation exposures should be 0.5 Gy or less. © RSNA, 2012.

    Even if neoadjuvant chemotherapy (NACT) and oncoplastic techniques have increased the breast conserving surgery rate, mastectomy is still a standard for multifocal or extensive breast cancers (BC). In the prospect of increasing breast reconstruction, an alternative therapeutic protocol was developed combining NACT with neoadjuvant radiation therapy (NART), followed by mastectomy with immediate breast reconstruction (IBR). The oncological safety of this therapeutic plan still needs further exploration. We assessed pathological complete response (pCR) as a surrogate endpoint for disease free survival. Between 2010 and 2016, 103 patients undergoing mastectomy after NACT and NART were recruited. After CT and RT were administrated, a completion mastectomy with IBR by latissimus dorsi flap was achieved 6 to 8 weeks later. pCR was defined by the absence of residual invasive disease in both nodes and breast. Histologic response was analyzed for each immunohistochemical subset. pCR was obtained for 53.4% of the patients. This pCR rate was higher in hormonal receptor negative (HER2 and triple negative) patients when compared to luminal tumours (69.7% vs 45.7%, p=0.023). The pCR rate found in this study is higher than those published in studies analyzing NACT (12.5%-27.1%). This can be explained by the combination of anthracycline and taxane, the use of trastuzumab when HER2 was overexpressed but also by RT associated to NACT. Inverting the sequence protocol for BC, requiring both CT and RT, allows more IBR without diminishing pCR and should therefore be considered as an acceptable therapeutic option.

    2017-04-01

    Brain metastases represent the first cause of malignant brain tumor. Without radiation therapy, prognosis was poor with fast neurological deterioration, and a median overall survival of one month. Nowadays, therapeutic options depend on brain metastases presentation, extra brain disease, performance status and estimated prognostic (DS GPA). Therefore, for oligometastatic brain patients with a better prognosis, this therapeutic modality is controversial. In fact, whole-brain radiation therapy improves neurological outcomes, but it can also induce late neuro-cognitive sequelae for long-term survivors of brain metastases. Thus, in this strategy for preserving good cognitive functions, stereotactic radiation therapy is a promising treatment. Delivering precisely targeted radiation in few high-doses in one to four brain metastases, allows to reduce radiation damage to normal tissues and it should allow to decrease radiation-induced cognitive decline. In this paper, we will discuss about therapeutic strategies (radiation therapy and surgery) with their neuro-cognitive consequences for brain metastases patients and future concerning preservation of cognitive functions.

    This phase II trial evaluated the effect of neoadjuvant chemotherapy with or without second-look surgery before craniospinal irradiation on response rates and survival outcomes in children with newly diagnosed non-germinomatous germ cell tumors. Induction chemotherapy consisted of six cycles of carboplatin/etoposide alternating with ifosfamide/etoposide. Patients demonstrating less than complete response after induction chemotherapy were encouraged to undergo second-look surgery. Patients who did not achieve complete response or partial response after chemotherapy with or without second-look surgery proceeded to high-dose chemotherapy with thiotepa and etoposide and autologous peripheral blood stem-cell rescue before craniospinal irradiation. The study included 102 patients treated between January 2004 and July 2008. Median age was 12 years, and 76% were male; 53.9% had pineal region masses, and 23.5% had suprasellar lesions. Sixty-nine percent of patients achieved complete response or partial response with neoadjuvant chemotherapy. At 5 years, event-free survival was 84% ± 4% (SE) and overall survival was 93% ± 3%. During the median follow-up of 5.1 years, 16 patients recurred or progressed, with seven deaths after relapse. No deaths were attributed to therapy-related toxicity. Relapse occurred at the site of primary disease in 10 patients, at a distant site in three patients, or both in one patient. In two patients, progression was detected by marker increase alone. Increased serum α-fetoprotein was a negative prognostic variable. Histologic subtype and increase of beta-human chorionic gonadotropin were not significantly correlated with worse outcomes. Neoadjuvant chemotherapy with or without second-look surgery achieved high response rates contributing to excellent survival outcomes in children with newly diagnosed non-germinomatous germ cell tumors. This regimen should be included as a backbone for further studies. © 2015 by American Society of Clinical

    Purpose: To evaluate outcomes of conservative surgery and radiation therapy (RT) treatment in patients with dermatofibrosarcoma protuberans. Methods and Materials: We retrospectively reviewed the medical records of 53 consecutive dermatofibrosarcoma protuberans patients treated with surgery and preoperative or postoperative radiation therapy between 1972 and 2010. Median tumor size was 4 cm (range, 1-25 cm). Seven patients (13%) were treated with preoperative RT (50-50.4 Gy) and 46 patients (87%) with postoperative RT (60-66 Gy). Of the 46 patients receiving postoperative radiation, 3 (7%) had gross disease, 14 (30%) positive margins, 26 (57%) negative margins, and 3 (7%) uncertain margin status. Radiation dose ranged from 50 to 66 Gy (median dose, 60 Gy). Results: At a median follow-up time of 6.5 years (range, 0.5 months-23.5 years), 2 patients (4%) had disease recurrence, and 3 patients (6%) had died. Actuarial overall survival was 98% at both 5 and 10 years. Local control was 98% and 93% at 5 and 10 years, respectively. Disease-free survival was 98% and 93% at 5 and 10 years, respectively. The presence of fibrosarcomatous change was not associated with increased risk of local or distant relapse (P=.43). One of the patients with a local recurrence had gross residual disease at the time of RT and despite RT to 65 Gy developed both an in-field recurrence and a nodal and distant recurrence 3 months after RT. The other patient with local recurrence was found to have in-field recurrence 10 years after initial treatment. Thirteen percent of patients had an RT complication at 5 and 10 years, and 9% had a moderate or severe complication at 5 and 10 years. Conclusions: Dermatofibrosarcoma protuberans is a radioresponsive disease with excellent local control after conservative surgery and radiation therapy. Adjuvant RT should be considered for patients with large or recurrent tumors or when attempts at wide surgical margins would result in significant morbidity.

    Primary lymphoma in the region of the liver bed mimicking hilar cholangiocarcinoma or Klatskin tumor is very rare. A patient presented with obstructive jaundice along with right upper quadrant pain, weight loss, and decreased appetite. Apart from altered liver function, her lactate dehydrogenase was significantly elevated, and imaging studies showed prominent lesion close to the liver bed with localized lymphadenopathy. The diagnosis ultimately reached at by biopsy and immunohistochemical staining was diffuse large B-cell lymphoma. Such cases are very infrequent, but demand awareness. The sooner the diagnosis can be reached by minimally invasive procedures, the earlier chemotherapy with rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone can be initiated and laparotomy can be avoided as chemotherapy is the mainstay of treatment, even in the presence of jaundice.

    No data are available regarding the management of cancer patients requiring interruption of long-term vitamin-K antagonist (VKA) therapy. For this purpose, we tested the efficacy and safety of fixed doses of low-molecular weight heparin (LMWH) in substitution of VKA because of invasive procedures or chemotherapy-induced thrombocytopenia. In cancer patients on VKA, therapy was discontinued 5 ± 1 days before surgery or chemotherapy. Heparin was given at prophylactic dosage in patients at low risk and at fixed subtherapeutic doses (3,800 or 4,000 UI anti-FXa, b.i.d.) in those at high-risk for thrombosis. LMWH was reinitiated 12 hr after surgery and VKA the day after. In patients receiving chemotherapy, LMWH was reinitiated 12/24 hr after obtaining a stable platelet count ≥ 30,000 mmc(3) and VKA after a stable platelet count ≥ 50,000 mmc(3) . Thromboembolism and major bleeding events were recorded from the time of VKA suspension to 30 ± 2 days postprocedure or until the next chemotherapy. Overall, 156 patients (56.4% at low risk and 43.5% at high risk for thrombosis) were enrolled; 34.6% underwent major surgery, 40.4% nonmajor surgery, and 25% chemotherapy. Thrombotic events occurred in five patients [3.2%, 95% confidence interval (CI): 1.41-7.27], four belonging to the high-risk and one to the low-risk group. Major bleeding occurred in five patients (3.2%, 95 CI: 1.41-7.27), all belonging to the high-risk group (three during major surgery and two during chemotherapy). In conclusion, LMWH given at fixed subtherapeutic is a feasible and relatively safe approach for bridging therapy in cancer patients on long-term VKA.

    High-energy gamma probes have recently become commercially available, developed for {sup 18}F-FDG probe-guided surgery. The radiation received by the staff in the operating room might limit the use of it, but has never been determined. We therefore wanted to measure the absorbed staff doses at operations where patients had received a preoperative injection of {sup 18}F-FDG. Thirty-four patients with different cancers (breast cancer, melanoma, gastrointestinal cancers, respectively) were operated. At every operation the surgeon was monitored with a TLD tablet on his finger of the operating hand and a TLD tablet on the abdomen. The surgeon and anaesthesiologist were also monitored using electronic dosimeters placed in the trousers lining at 25 operations. The dose rate to the surgeon's abdominal wall varied between 7.5-13.2 {mu}Sv/h, depending on tumour location. The doses to the anaesthesiologists and the finger doses to the surgeon were much lower. About 350-400 MBq, i.e. ca. eight times higher activities than those used in the present study are supposed to be necessary for guiding surgery. It can be calculated from the body doses measured that a surgeon can perform between 150-260 h of surgery without exceeding permissible limits for professional workers. The radiation load to the operating staff will generally be so small that it does not present any limitation for FDG-guided surgery. However, it is recommended to monitor the surgical staff considering that the surgeon may be exposed to other radiation sources, and since the staff often includes women of child-bearing age.

    Full Text Available Abstract Background Neoadjuvant chemoradiation (NCR prior to resection of extremity soft tissue sarcoma (STS has been studied, but data are limited. We present outcomes with NCR using a variety of chemotherapy regimens compared to neoadjuvant radiation without chemotherapy (NR and surgery alone (SA. Methods We conducted a retrospective chart review of 112 cases. Results Treatments included SA (36 patients, NCR (39 patients, and NR (37 patients. NCR did not improve the rate of margin-negative resections over SA or NR. Loco-regional relapse-free survival, distant metastases-free survival, and overall survival (OS were not different among the treatment groups. Patients with relapsed disease (OR 11.6; p = 0.01, and tumor size greater than 5 cm (OR 9.4; p = 0.01 were more likely to have a loco-regional recurrence on logistic regression analysis. Significantly increased OS was found among NCR-treated patients with tumors greater than 5 cm compared to SA (3 year OS 69 vs. 40%; p = 0.03. Wound complication rates were higher after NCR compared to SA (50 vs. 11%; p = 0.003 but not compared to NR (p = 0.36. Wet desquamation was the most common adverse event of NCR. Conclusions NCR and NR are acceptable strategies for patients with STS. NCR is well-tolerated, but not clearly superior to NR.

    To quantify through environmental audit the radiation dose that urologists receive during surgery in the lithotomy position, and to quantify the dose reduction achieved by altering exposure techniques and personal protective equipment use. Simulated surgery in the lithotomy position using an anthropomorphic phantom as a patient and a SimMan(®) mannequin as the surgeon. Pulsed fluoroscopy, focus-to-skin distance (FSD), collimation, and addition of a lead shield at the table end were individually and collectively introduced after a control study. Scattered X-ray dose rates to the simulated surgeon's eye, thyroid, trunk, external genitalia, and leg were measured with each of the technique adjustments. The absorbed dose in air at the phantom skin was measured throughout. Results were compared to discover surgeon dose rates with technique alteration. Increasing FSD leads to a rise in surgeon eye dose, and table end lead protection increases the patient skin dose. Use of all the dose-reduction techniques together reduces the dose to the patient, and a surgeon's trunk dose is decreased by 95%, external genitalia dose by 99%, and leg dose by 97%. Sitting to perform fluoroscopically guided surgery in the lithotomy position increases surgeon dose by a median value of 17%, with the external genitalia dose increased by 78% compared with the standing position. This study describes effective methods of dose reduction that are easy to instigate. The resulting reduction in radiation dose during urology procedures meets the requirements of international guidelines and legislation. This change in practice improves patient care and reduces risk to urologists from occupational exposure to radiation. By combining all of the dose-reduction techniques, urologists should never reach the threshold for deterministic radiation effects to their eyes during their career, and they will have a significantly lower chance of stochastic risks such as cancer.

    Aim of the study is to assess the reliability and correlation with surgical peritoneal cancer index (PCI) of combined PET/CT and ceCT scans (PET/ceCT) performed in a session in patients with peritoneal carcinomatosis candidates for cytoreductive surgery (CS) and hyperthermic intraperitoneal chemotherapy (HIPEC). We retrospectively analyzed data collected from 27 patients with different types of peritoneal carcinomatosis candidates to CS + HIPEC who underwent FDG PET/ceCT in a single session. Two nuclear medicine physicians and two radiologists independently and blindly evaluated PET/CT and ceCT imaging, respectively. In the case of discordance, the consensus was reached by a discussion between the specialists. Moreover, the combined images were evaluated by all the specialists in consensus. The PCIs obtained from surgical look, PET/CT, ceCT, and PET/ceCT were compared with each other. The coefficients of correlation (r) were calculated. The study was conducted after approval of local ethics committee. Surgical PCI was available in 21 patients. The coefficient of correlation between PCI of PET/CT and surgery was 0.528, while it resulted higher between PET/ceCT and surgery (r = 0.878), very similar to ceCT and surgery (r = 0.876). The r coefficient between surgical PCI and PET/CT was higher in patients with a non-mucinous cancer (n = 12) than the counterpart (0.601 vs. 0.303) and the addition of ceCT significantly increases the correlation (r = 0.863), which is anyway similar to ceCT alone (r = 0.856). PET/ceCT as single examination is more accurate than PET/CT but not than ceCT alone for the definition of PCI in a selected group of patients candidates to CS + HIPEC.

    The effect of postmastectomy radiation therapy (PMRT) on immediately reconstructed abdominal wall-based tissue remains imprecisely defined. We evaluated evidence from all fields involved in care of the breast cancer patient in order to advance a unified recommendation regarding this therapeutic sequence. We performed a MEDLINE and manual reference search to identify studies of PMRT with immediate autologous breast reconstruction. Inclusion criteria required studies to describe patients, flaps, and complication rates. Analyses were based on a random effects model. Surgical and radiation oncology literature was reviewed. Eleven retrospective studies of 337 patients with an average follow-up of 18-60 months (out of 268 patients) were selected for inclusion. Overall rates of fat necrosis, revisional surgery, volume loss, and fibrosis/contracture ranged from 16.9% to 35.4%. One out of 260 patients experienced total flap loss. There was an increased probability of fat necrosis in the irradiated breast (OR = 3.13, 95% CI = 1.42-6.89, P = 0.005) among three studies with non-irradiated controls. Five studies evaluated aesthetics with variable outcomes. There is mixed evidence for the utility of PMRT with immediate autologous abdominal wall breast reconstruction. Further investigation requires prospective studies with collaboration among surgical oncologists, radiation oncologists, and plastic surgeons. © 2014 Wiley Periodicals, Inc.

    We adopted ABVD chemotherapy with risk-adapted radiation therapy (RT) as first-line therapy for children, adolescents and young adults with Hodgkin lymphoma (HL) in British Columbia in 2004. Patients ≤ 25 years diagnosed from 2004 to 2013 with all stages of HL who received ABVD as initial therapy were included. Among 55 children (age adults (18-25 year), there were no significant differences among age groups for sex, histologic subtype, tumour bulk, B symptoms, prognostic risk groups or treatment received. The rates of complete response, partial response and progressive disease were 84%, 7% and 10% for children and 95%, 4% and 1% for young adults (P=0.01), respectively. Treatment failures in children all occurred within one year of completion, while 8/21 (38%) relapses in young adults occurred later (P=0.04). With a median follow-up of 66 months the 5-year progression-free (PFS) and overall survival (OS) were 85 ± 3% and 97 ± 1%, respectively. For limited stage disease, PFS was 90 ± 7% for children and 93 ± 3% for young adults (P=0.65); OS was 100% for both. For advanced stage patients, PFS and OS were also similar for the children and young adults (77 ± 7% versus 81 ± 4%; P=0.38 and OS 90 ± 6% versus 97 ± 2%; P=0.17). The rate of consolidative RT was low (21%) and did not differ between age groups. ABVD is an effective treatment in children, adolescents and young adults with HL. Children were less likely to achieve complete response and demonstrated earlier relapses compared to young adults. RT may be omitted for the majority of patients while maintaining excellent 5-year OS.

    In 1996, a multicenter randomized study comparing after breast-conservative surgery. sequential vs concurrent adjuvant chemotherapy (CT) with radiation therapy (RT) was initiated (ARCOSEIN study). Seven hundred sixteen patients were included in this trial. After a median follow-up of 6.7 (4.3 -9) years, we decided to prospectively evaluate the late effects of these two strategies. Patients and methods - A total of 297 patients were asked to follow-up from the five larger including institutions. Seventy-two percent (214 patients) were eligible for late toxicity. After breast-conserving surgery with axillary dissection, patients were treated either with sequential treatment with CT first followed by RT (arm A) or CT administered concurrently with RT (arm B). In all patients, CT regimen combined mitoxantrone (12 mg/m{sup 2}). 5-FU (500 mg/m{sup 2}), and cyclophosphamide (500 mg/m{sup 2}), 6 cycles (day 1-day 21). In arm B, patients received concurrently the first 3 cycles of CT with RT. In arm A, RT started 3 to 5 weeks after the 6. cycle of CT. Conventional RT was delivered to the whole breast using a 2 Gy-fraction protocol to a total dose of 50 Gy ({+-} boost to the primary tumour bed). The assessment of toxicity was blinded to treatment and was graded by the radiation oncologist according to the LENT-SOMA scale. Skin pigmentation was also evaluated using a personal 5-points scoring system (excellent, good, moderate, poor, very poor). Results - Among the 214 evaluated patients, 107 were treated in each arm. The two populations were homogeneous for patients', tumors' and treatment characteristics. Subcutaneous fibrosis (SF), telangiectasia (T), skin pigmentation (SP), and breast atrophy (BA) were significantly increased in arm B. Twenty patients experienced grade superior or equal to 2 (SF) in arm B vs five in arm A (P 0.003). Twenty-five and seven patients showed grade superior or equal to 2 (T) in ann B and A, respectively (P = 0.001). Forty-four and

  17. Evaluating contextual processing in diffusion MRI: application to optic radiation reconstruction for epilepsy surgery.

    Full Text Available Diffusion MRI and tractography allow for investigation of the architectural configuration of white matter in vivo, offering new avenues for applications like presurgical planning. Despite the promising outlook, there are many pitfalls that complicate its use for (clinical application. Amongst these are inaccuracies in the geometry of the diffusion profiles on which tractography is based, and poor alignment with neighboring profiles. Recently developed contextual processing techniques, including enhancement and well-posed geometric sharpening, have shown to result in sharper and better aligned diffusion profiles. However, the research that has been conducted up to now is mainly of theoretical nature, and so far these techniques have only been evaluated by visual inspection of the diffusion profiles. In this work, the method is evaluated in a clinically relevant application: the reconstruction of the optic radiation for epilepsy surgery. For this evaluation we have developed a framework in which we incorporate a novel scoring procedure for individual pathways. We demonstrate that, using enhancement and sharpening, the extraction of an anatomically plausible reconstruction of the optic radiation from a large amount of probabilistic pathways is greatly improved in three healthy controls, where currently used methods fail to do so. Furthermore, challenging reconstructions of the optic radiation in three epilepsy surgery candidates with extensive brain lesions demonstrate that it is beneficial to integrate these methods in surgical planning.

    Gliomas, the most common primary brain tumors, are diffusive and highly invasive. The standard treatment for brain tumors consists of a combination of surgery, radiation therapy and chemotherapy. Over the past few years, mathematical models have been applied to study untreated and treated brain tumors. In an effort to improve treatment strategies, we consider a simple spatio-temporal mathematical model, based on proliferation and diffusion, that incorporates the effects of radiotherapeutic and chemotherapeutic treatments. We study the effects of different schedules of radiation therapy, including fractionated and hyperfractionated external beam radiotherapy, using a generalized linear quadratic (LQ) model. The results are compared with published clinical data. We also discuss the results for combination therapy (radiotherapy plus temozolomide, a new chemotherapy agent), as proposed in recent clinical trials. We use the model to predict optimal sequencing of the postoperative (combination of radiotherapy and adjuvant, neo-adjuvant or concurrent chemotherapy) treatments for brain tumors.

    Purpose: While consolidation radiation therapy (i.e., RT administered after chemotherapy) is routine treatment for patients with early-stage diffuse large B-cell lymphoma (DLBCL), the role of consolidation RT in stage III-IV DLBCL is controversial. Methods and Materials: Cases of patients with stage III-IV DLBCL treated from 1991 to 2009 at Duke University, who achieved a complete response to chemotherapy were reviewed. Clinical outcomes were calculated using the Kaplan-Meier method and were compared between patients who did and did not receive RT, using the log-rank test. A multivariate analysis was performed using Cox proportional hazards model. Results: Seventy-nine patients were identified. Chemotherapy (median, 6 cycles) consisted of anti-CD20 antibody rituximab combined with cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP; 65%); cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP; 22%); or other (13%). Post-chemotherapy imaging consisted of positron emission tomography (PET)/computed tomography (CT) (73%); gallium with CT (14%); or CT only (13%). Consolidation RT (median, 25 Gy) was given to involved sites of disease in 38 (48%) patients. Receipt of consolidation RT was associated with improved in-field control (92% vs. 69%, respectively, p = 0.028) and event-free survival (85% vs. 65%, respectively, p = 0.014) but no difference in overall survival (85% vs. 78%, respectively, p = 0.15) when compared to patients who did not receive consolidation RT. On multivariate analysis, no RT was predictive of increased risk of in-field failure (hazard ratio [HR], 8.01, p = 0.014) and worse event-free survival (HR, 4.3, p = 0.014). Conclusions: Patients with stage III-IV DLBCL who achieve negative post-chemotherapy imaging have improved in-field control and event-free survival with low-dose consolidation RT.

    Extranodal natural killer (NK)/T cell lymphoma, nasal type (ENKTL) is an aggressive non-Hodgkin lymphoma and the majority of ENKTL cases are diagnosed at the localized stage. Radiotherapy in combination with chemotherapy has been used for localized ENKTL, but the optimal combination treatment modality and the best first-line chemotherapy regimen have not been defined. In this retrospective study, 44 patients with newly diagnosed, stages I/II ENKTL were enrolled and received intensity-modulated radiation therapy (IMRT, 50-56 Gy) followed by GDP (gemcitabine, dexamethasone, and cisplatin) chemotherapy. The median number of chemotherapy cycles per patient was 4 (range, 2-6 cycles). At the end of treatment, the overall response rate was 95% (42/44), including 39 patients (89%) who attained complete response. Two patients developed systemic progression after IMRT. With a median follow-up of 37.5 months, the 3-year overall survival (OS) rate and progression-free survival (PFS) rate were 85% (95% CI, 74 to 96%) and 77% (95% CI, 64 to 91%), respectively. Locoregional and systemic failure rates for this treatment were 9% (4/44) and 14% (6/44), respectively. The most common grades 3 to 4 adverse events included leukopenia (37%), neutropenia (34%), and mucositis (25%). No treatment-related deaths were observed. This study suggested high efficacy and low toxicity of IMRT followed by GDP regimen chemotherapy for newly diagnosed stage I/II ENKTL patients. These results require further investigation in prospective trials.

All patients were planned to receive chemoradiotherapy after surgery. The primary end-points were organ preservation and progression-free-survival. SPSS version 17 was used for data analysis. Median follow-up was 16 months. The median age of the patients was 62 years old (23-75 years. Man/woman ratio was 1.13. The primary site of the tumor was the tongue in most patients (48%. No significant difference was observed between pathologic characteristics of the two groups. Chemotherapy group showed 16% complete pathologic response to TPF. No significant difference in organ preservation surgery or overall survival was detected. However, the patients in the chemotherapy group had longer progression-free-survival (P=0.014. Surgery followed by chemoradiotherapy with or without TPF induction results in similar survival time. However, progression-free-survival improves with the TPF induction chemotherapy. Studies with more patents and new strategies are recommended to evaluate organ preservation improvement and long-term outcomes.

    There is substantial evidence that tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) causes apoptosis via activation of death receptors 4 and 5 (DR4 and DR5). We sought to determine the therapeutic potential of TRA-8 (anti-DR5 monoclonal antibody) in combination with chemotherapy and radiation therapy in a cervical cancer model. DR5 expression in 7 human cervical cancer cell lines was analyzed by indirect immunofluorescence using murine TRA-8 in combination with flow cytometry. Cell lines were treated with TRA-8 alone or in combination with cisplatin, topotecan, or radiation, and cytotoxicity assays were performed. Mice were inoculated with ME-180 cancer cells and treated with different combinations of therapy. Animals receiving antibody were injected intraperitoneally with 200 microg of TRA-8. Animals received 9 Gy 60Co radiation divided into 3 fractions and 3 intraperitoneal doses of cisplatin (6 mg/kg) 1 h before radiation. A similar experiment was performed using topotecan (2 mg/kg) as the chemotherapeutic agent. DR5 was expressed to a varying degree on the cervical cancer cell lines. Combination treatment with TRA-8 and chemotherapy or radiation resulted in synergistic cytotoxicity in vitro. In vivo, combination therapy with TRA-8, cisplatin, and radiation produced tumor growth inhibition that was significantly greater than the other groups. Similar results were seen in combination studies with topotecan. These data suggest that DR5 is a good target for activation of the apoptotic pathway. Monoclonal antibodies such as TRA-8 may play an important role in the development of an effective treatment strategy for patients with advanced cervical cancer.

    Two cases of radiation enterocolitis with markedly impaired QOL for a long period were reported. Case 1: A 61 years old female. She received 60 Gy irradiation post hysterectomy and ovariectomy due to uterine cancer at the age of 39 y. She suffered from fecal incontinence and anal pain at 58 y, was diagnosed to have radiation colitis. She was hospitalized due to neurosis, anal pain and hypertension at 59 y. She received nephrostomy due to hydronephrosis and ureterostenosis at 60 y, and colostomy and ileal conduit formation due to anal pain and dyschezia. Case 2: A 70 years old female who received 60 Gy irradiation post surgery similar to case 1 at the age of 61 y. She suffered from ileus, intestinal retention and hydronephrosis thereafter. She was hospitalized due to metastasis of the cancer to sacred bone, and received further 40 Gy radiation therapy at the age of 65 y. Up to the present, she received several operations such as ileostomy, nephrostomy and hemorrhoids excision. It is important for surgeons to understand the actual QOL of patients with radiation enterocolitis. (K.H.)

    Relapse remains a significant problem in patients with metastatic osteosarcoma. The response to carboplatin of patients with newly diagnosed metastatic or unresectable osteosarcoma was assessed in an upfront phase II window, which was followed-up by surgery and intensive multiagent chemotherapy. Thirty-seven patients, ages 3 to 23 years with histologically confirmed diagnoses of osteosarcoma, were treated between January 1992 and November 1994 with carboplatin 1,000 mg/m2 per dose administered as a 48-hour continuous infusion. Two courses were administered in 3-week intervals, depending on marrow recovery. After radiographic reevaluation, patients underwent surgical removal of tumor (if feasible) and then 40 weeks of chemotherapy with high-dose methotrexate, ifosfamide, doxorubicin, and cisplatin. One of the 37 evaluable patients demonstrated a partial response to carboplatin; there were no complete responses. Patients were additionally analyzed by the response of pulmonary metastases to therapy and the extent of tumor necrosis of the primary lesion. By these criteria, 8 of 37 (22%) of patients showed a response at one or more sites, whereas 20 of 37 (54%) had unequivocal disease progression. Severe myelosuppression was the major toxicity. The projected 3-year event-free and overall survival rates were 23.9% and 31.9%, respectively. Only 1 of 17 patients with unresectable disease or distant bone metastases remains alive, in contrast to 6 of 17 patients with the lung as their only metastatic site and two of three patients with resected regional bone metastases. Continuous-infusion carboplatin demonstrated limited activity as an upfront agent in patients with metastatic osteosarcoma at diagnosis, even at doses that result in severe and prolonged myelosuppression. Patients with isolated pulmonary metastases or resectable bone metastases have a longer median survival time and greater chance of long-term survival than do patients with unresectable bone disease, for whom

    Full Text Available BACKGROUND: Despite the best standard treatment, optimal cytoreductive surgery (CRS and platinum/taxane-based chemotherapy, prognosis of advanced epithelial ovarian carcinoma (EOC remains poor. Recently, CRS plus hyperthermic intraperitoneal chemotherapy (HIPEC has been developed to treat peritoneal carcinomatosis (PC. This study was to evaluate the efficacy and safety of CRS+HIPEC to treat PC from advanced/recurrent EOC. METHODS: Forty-six PC patients from advanced EOC (group A or recurrent EOC (group B were treated by 50 CRS+HIPEC procedures. The primary endpoints were progression-free survival (PFS and overall survival (OS; the secondary endpoints were safety profiles. RESULTS: The median OS was 74.0 months [95% confidence interval (CI 8.5-139.5] for group A versus 57.5 months (95% CI 29.8-85.2 for group B (P = .68. The median PFS was not reached for group A versus 8.5 months (95% CI 0-17.5 for group B (P = .034. Better median OS correlated with peritoneal cancer index (PCI 20 group, P = .01, complete cyroreduction (residual disease ≤ 2.5 mm [79.5 months for completeness of cytoreduction (CC score 0-1 vs 24.3 months for CC 2-3, P = .00], and sensitivity to platinum (65.3 months for platinum-sensitive group vs 20.0 for platinum-resistant group, P = .05. Serious adverse events occurred in five patients (10.0%. Multivariate analysis identified CC score as the only independent factor for better survival. CONCLUSION: For advanced/recurrent EOC, CRS+HIPEC could improve OS with acceptable safety.

    We report a case of advanced pancreatic cancer with liver and lung metastases that was well controlled over one year by combination therapy with systemic chemotherapy, radiation and hepatic arterial infusion in an outpatient setting. The patient was a 74-year-old woman. Chief complaints were back pain and anorexia. She was diagnosed with pancreas cancer with liver and lung metastases at the time of first visit. We started systemic chemotherapy with gemcitabine 1 g/body and 5-FU 1 g/body alternately every other week on an outpatient basis. At 1.5 months (M) after initiation of chemotherapy, we started radiation therapy to the main tumor at a total dose of 40 Gy. After radiation, chemotherapy was resumed. As a result, the size of the main tumor decreased but metastatic liver tumors got larger. Then we changed to combination therapy with systemic chemotherapy (gemcitabine and 5-FU) and hepatic arterial infusion (5-FU weekly). Liver metastases almost disappeared after 7.5 M. Despite all these treatments, however, the number of metastatic lung tumors increased. The patient was hospitalized for 15 M and died after 17 M. We focused on and succeeded in the prolongation of lifetime and maintenance of QOL by combination therapy with systemic chemotherapy, radiation and hepatic arterial infusion therapy.

    Sixty-eight long-term survivors of childhood cancer were evaluated for dental and maxillofacial abnormalities. Forty-five patients had received maxillofacial radiation for lymphoma, leukemia, rhabdomyosarcoma, and miscellaneous tumors. Forty-three of the 45 patients and the remaining 23 who had not received maxillofacial radiation also received chemotherapy. Dental and maxillofacial abnormalities were detected in 37 of the 45 (82%) radiated patients. Dental abnormalities comprised foreshortening and blunting of roots, incomplete calcification, premature closure of apices, delayed or arrested tooth development, and caries. Maxillofacial abnormalities comprised trismus, abnormal occlusal relationships, and facial deformities. The abnormalities were more severe in those patients who received radiation at an earlier age and at higher dosages. Possible chemotherapeutic effects in five of 23 patients who received treatment for tumors located outside the head and neck region comprised acquired amelogenesis imperfecta, microdontia of bicuspid teeth, and a tendency toward thinning of roots with an enlarged pulp chamber. Dental and maxillofacial abnormalities should be recognized as a major consequence of maxillofacial radiation in long-term survivors of childhood cancer, and attempts to minimize or eliminate such sequelae should involve an effective interaction between radiation therapists, and medical and dental oncologists.

Adjuvant radiotherapy was defined as postoperative external beam radiation to the pelvis (30–50 Gray/10–25 fractions at five fractions/week. The primary end point was LRFFS, and the secondary end point was OS. Kaplan–Meier curves were compared using the log-rank test. Cox regression analyses were used to determine prognosticators for LRFFS and OS.Results: The median follow-up time of all patients was 75 months, with a 5-year LRFFS of 62.1%. The 2-year and 5-year LRFFS rates were longer for those who received AR than for those who did not receive AR (83.4% vs 70.3%; 78% vs 55.3%; P=0.013. The 5-year OS of all patients was 56.2%, and no significant differences were observed in the 2-year and 5-year OS rates between these two groups (82.7% vs 71.4%; 64.1% vs 51.7%; P=0.067. Importantly, in patients with leiomyosarcoma, the 2-year and 5-year LRFFS and OS rates were longer for those who received AR than for those who did not receive AR (P=0.04 and P=0.02 for the 2-year and 5-year LRFFS, respectively.Conclusion: Patients with uterine sarcoma who were treated with AR after surgery demonstrated an improved LRFFS compared with those who were treated with surgery alone, especially those patients with leiomyosarcoma.

Methods: Using a Markov model, the cost-effectiveness of PDS was compared to that of NACT. We modeled cost and survival inputs using data from women in the SEER-Medicare database with ovarian cancer treated by either PDS or NACT between 1992 and 2009. Direct and indirect costs were discounted by an annual rate of 3%. Utility weights were obtained from published data. The incremental cost-effectiveness ratio (ICER of PDS compared to NACT was calculated. Results: In our model, women with stage IIIC EOC had a higher mean adjusted treatment cost for PDS when compared to NACT ($31,945 vs $30,016 but yielded greater quality-adjusted life-years (QALYs (1.79 vs 1.69. The ICER was $19,359/QALY gained. Women with stage IV EOC had a higher mean adjusted treatment cost following PDS when compared to NACT ($31,869 vs $27,338 but yielded greater QALYs (1.69 vs 1.66. The ICER was $130,083/QALY gained. A sensitivity analysis showed that for both PDS and NACT the ICER was sensitive to incremental changes in the utility weight. Conclusion: PDS is significantly more cost-effective for women with stage IIIC when compared to NACT. In women with stage IV EOC, PDS is also more cost-effective though the QALYs gained are much more costly and exceed a $50,000 willingness to pay.

    Ketogenic diets are low in carbohydrates and high in fat, which forces cells to rely more heavily upon mitochondrial oxidation of fatty acids for energy. Relative to normal cells, cancer cells are believed to exist under a condition of chronic mitochondrial oxidative stress that is compensated for by increases in glucose metabolism to generate reducing equivalents. In this study we tested the hypothesis that a ketogenic diet concurrent with radiation and chemotherapy would be clinically tolerable in locally advanced non-small cell lung cancer (NSCLC) and pancreatic cancer and could potentially exploit cancer cell oxidative metabolism to improve therapeutic outcomes. Mice bearing MIA PaCa-2 pancreatic cancer xenografts were fed either a ketogenic diet or standard rodent chow, treated with conventionally fractionated radiation (2 Gy/fraction), and tumor growth rates were assessed daily. Tumors were assessed for immunoreactive 4-hydroxy-2-nonenal-(4HNE)-modfied proteins as a marker of oxidative stress. Based on this and another previously published preclinical study, phase 1 clinical trials in locally advanced NSCLC and pancreatic cancer were initiated, combining standard radiation and chemotherapy with a ketogenic diet for six weeks (NSCLC) or five weeks (pancreatic cancer). The xenograft experiments demonstrated prolonged survival and increased 4HNE-modfied proteins in animals consuming a ketogenic diet combined with radiation compared to radiation alone. In the phase 1 clinical trial, over a period of three years, seven NSCLC patients enrolled in the study. Of these, four were unable to comply with the diet and withdrew, two completed the study and one was withdrawn due to a dose-limiting toxicity. Over the same time period, two pancreatic cancer patients enrolled in the trial. Of these, one completed the study and the other was withdrawn due to a dose-limiting toxicity. The preclinical experiments demonstrate that a ketogenic diet increases radiation sensitivity

    BACKGROUND In a retrospective study of SWOG-S8710/INT-0080 (radical cystectomy [RC] alone vs 3 cycles of MVAC neoadjuvant chemotherapy [NC] before RC for bladder cancer), factors associated with improved overall survival (OS) included pathologic complete response (pCR) defined as P0, treatment with NC, completion of RC with negative margins and ≥10 pelvic lymph nodes (LNs) removed. METHODS We used stratified Cox regression to retrospectively study the association of quality of pathologic response post-RC with OS in the subset of S8710 patients that received NC and RC with negative margins. RESULTS Of 154 patients who received NC, 68 (44.2%) were

    Standard therapy for locally advanced rectal cancer (LARC) is preoperative chemoradiotherapy and postoperative chemotherapy. At Memorial Sloan-Kettering Cancer Center (MSKCC) the authors began offering FOLFOX (5-fluorouracil, leucovorin, and oxaliplatin) as initial treatment for patients with high-risk LARC to target micrometastases while treating the primary tumor. The purpose of this study is to report the safety and efficacy of initial FOLFOX given before chemoradiotherapy on tumor downsizing and pathologic complete response (pathCR) in LARC. The records of patients with stage II/III rectal cancer treated at MSKCC between 2007 and 2012 were reviewed. Of approximately 300 patients with LARC treated at MSKCC, 61 received FOLFOX as initial therapy. Of these 61 patients, 57 received induction FOLFOX (median 7 cycles) followed by chemoradiation, and 4 experienced an excellent response, declined chemoradiation, and underwent total mesorectal excision (TME). Twelve of the 61 patients did not undergo TME: 9 had a complete clinical response (CCR), 1 declined despite persistent tumor, 1 declined because of comorbidities, and 1 developed metastatic disease. Among the 61 patients receiving initial FOLFOX, 22 (36%) had either a pathCR (n=13) or a CCR (n=9). Of the 49 patients who underwent TME, all had R0 resections and 23 (47%) had tumor response greater than 90%, including 13 (27%) who experienced a pathCR. Of the 28 patients who received all 8 cycles of FOLFOX, 8 experienced a pathCR (29%) and 3 a CCR (11%). No serious adverse events occurred that required a delay in treatment during FOLFOX or chemoradiation. FOLFOX and chemoradiation before planned TME results in tumor regression, a high rate of delivery of planned therapy, and a substantial rate of pathCRs, and offers a good platform for nonoperative management in select patients.

    This retrospective multi-institutional study addresses the role of surgical cytoreduction and hyperthermic intraperitoneal chemotherapy (HIPEC) in the treatment of multicystic peritoneal mesothelioma (MCPM). MCPM is an uncommon tumour with uncertain malignant potential and no current standard therapy. Additionally, poorly defined pathological and biological features of this disease were investigated. Twelve patients with MCPM underwent 14 procedures of cytoreduction and HIPEC in two Italian referral centres. Nine patients had recurrent disease after previous debulking (one operation in six patients, two in two, four in one). Biological markers related to mesothelioma origin and clinical features were assessed by immunohistochemical studies. Median follow-up was 64 months (range 5-148). Optimal cytoreduction (residual tumour nodules ≤2.5 mm) was performed in all the procedures. One grade IV postoperative complication (NCI/CTCAE v.3.0) and no operative death occurred. All the patients are presently alive with no evidence of disease, including two patients who underwent the procedure twice, due to locoregional disease recurrence. Five- and ten-year progression-free survival was 90% and 72%, accounting for a. statistically significant difference (P = 0.0001) with progression-free survival following previous debulking surgery (median 11 months; range 2-31). All cases showed low proliferative activity assessed by mitotic rate and Ki-67 expression. MCPM is a borderline tumour with a high propensity to local-regional recurrence. Definitive tumour eradication by means of cytoreduction and HIPEC seems more effective than debulking surgery in preventing disease relapse. Low mitotic rate and poor Ki-67 expression might be related to the peculiar behaviour of MCMP. Copyright © 2010 Elsevier Ltd. All rights reserved.

    A monoclonal antibody (TRA-8) has been developed that binds to death receptor 5 (DR5), one of two death receptors bound by tumor necrosis factor-related apoptosis-inducing ligand. The purpose of this study was to evaluate in vitro the binding and cytotoxicity of TRA-8 to human breast cancer cell lines. The antitumor efficacy of TRA-8 was evaluated in a xenograft human breast cancer murine model, as a single agent and in combination with chemotherapy or radiation therapy. Anti: The binding of TRA-8 to a panel of nine human breast cancer cell lines was evaluated by indirect immunofluorescence and flow cytometry. Cytotoxicity of TRA-8 alone and in the presence of Adriamycin or paclitaxel was measured in vitro using the ATP-lite assay. Antitumor efficacy was determined by treatment of nude mice bearing well-established s.c. DR5-positive 2LMP human breast cancer xenografts with TRA-8 alone or in combination with Adriamycin or paclitaxel. Tumor size and regression rates were determined. In addition, a study was carried out with TRA-8 and Adriamycin in combination with 3 Gy (60)Co irradiation of 2LMP xenografts on days 9 and 17. All nine human breast cancer cell lines expressed DR5 with TRA-8 reactivity varying from strongly to weakly positive. Four cell lines were sensitive to TRA-8 cytotoxicity with IC(50) of 17-299 ng/ml, whereas other cell lines had weak cytotoxicity or were resistant. In vivo studies demonstrated significant inhibition of growth of 2LMP xenografts by TRA-8 treatment alone. The combination of TRA-8 + Adriamycin or paclitaxel produced significant inhibition of tumor growth as compared with controls or either agent alone. An aggregate analysis of all 166 animals studied demonstrated that TRA-8 alone or in combination with Adriamycin, paclitaxel, or radiation produced a significant increase in tumor doubling time compared with any modality alone with mean doubling time in days of 12 (untreated), 14 (radiation), 17 (Adriamycin), 25 (paclitaxel), 39

    Approximately one-third of patients with localized osteosarcoma at presentation relapse as well as about three-fourths of the patients with metastases at diagnosis, about 90% of relapses are lung metastases. The role of lung metastasectomy remains to be determined. and methods: Three hundred and twenty three patients, 88 with resectable lung metastases at diagnosis and 235 with localized disease at presentation who relapsed with lung metastases were treated. A total of 498 lung surgeries and 607 thoracotomies were performed. The 5 year overall survival was 37%. Final outcome was significantly related to presence or absence of metastasis, time of first relapse and presence of local recurrences. According to stage of the disease, the rate of a 5 year event-free survival (EFS) was 36% for patients with localized disease who later relapsed and 9% for patients with resectable lung metastases at presentation (posteosarcoma treated with adjuvant or neoadjuvant chemotherapy, thoracotomy should always be considered regardless the number of previous lung relapses and the number of secondary pulmonary lesions.

    Full Text Available Abstract Background The combination of cytoreductive surgery (CRS and hyperthermic intraperitoneal chemotherapy (HIPEC is a curative treatment option for peritoneal carcinomatosis (PC. There have been few studies on the pulmonary adverse events (AEs affecting patient recovery after this treatment, thus this study investigated these factors. Methods Between January 2005 and December 2006, clinical data on all pulmonary AEs and the recovery progress were reviewed for 76 patients with after CRS and HIPEC. Patients with pulmonary interventions (thoracocenthesis and chest tubes were compared with the non-intervention patients. Two senior radiologists, blinded to the post-operative clinical course, separately graded the occurrence of pulmonary AEs. Results Of the 76 patients, 6 had needed thoracocentesis and another 6 needed chest tubes. There were no differences in post-operative recovery between the intervention and non-intervention groups. The total number of days on mechanical ventilation, the length of stay in the intensive care unit, total length of hospital stay, tumor burden, and an American Society of Anesthesiologists (ASA grade of greater than 2 were correlated with the occurrence of atelectasis and pleural effusion. Extensive atelectasis (grade 3 or higher was seen in six patients, major pleural effusion (grade 3 in seven patients, and signs of heart failure (grade 1–2 in nine patients. Conclusions Clinical and radiological post-operative pulmonary AEs are common after CRS and HIPEC. However, most of the pulmonary AEs did not affect post-operative recovery.

    This meta-analysis was performed to compare the outcomes between NACT-S and RT for locally advanced cancer cervix. The primary end points were survival benefits. The data sources for the search included medline, national library of medicine, and the embase search engines. Inclusion criteria included studies published between 2000 and 2012, and FIGO stages IB2 to IVA. Studies had to be properly randomized, prospective, or retrospective and only phase III. Further, the studies had to be with two arms, including one arm for neoadjuvant chemotherapy then-surgery (NACT-S), and the other arm for radiotherapy (RT). Data were collected from 1171 patients enrolled in seven phase III trials. The 5-year PFS (progression-free survival) for NACT-S and RT were 62 and 45.5 %, respectively. The 5-year OS for NACT-S and RT were 66 and 49 %, respectively. NACT-S was associated with better late toxicities compared to RT. NACT-S is a reasonable treatment option for locally advanced cancer cervix. It achieved better results than RT, especially for stages from IB2 to IIB.

    The purpose of radiation therapy (RT) for patients with spinal metastases is pain relief and control of paralysis. The aim of the present study was to assess pain relief using RT and to evaluate prognostic factors for pain control. We evaluated 97 consecutive patients, of mean age 62.7 years (range 28 to 86), with spinal metastases that had been treated by RT. We evaluated the effects of RT using pain level assessed using a drug grading scale based on the World Health Organization standards. The following potential prognostic factors for pain control of RT were evaluated using multivariate logistic regression analysis: age, gender, tumor type, performance status (PS), number of spinal metastases, and a history of chemotherapy. Among the 97 patients who underwent RT for pain relief, 68 patients (70.1%) presented with pain reduction. PS (odds ratio: 1.931; 95% confidence interval: 1.244 to 2.980) was revealed by multivariate logistic regression analysis to be the most important prognostic factor for pain control using RT. In conclusion, we found that RT was more effective for patients with spinal metastases while they maintained their PS.

    Mycosis fungoides is a T-cell lymphoma that arises in the skin and progresses at highly variable rates. Nonradomized studies have suggested that early aggressive therapy may improve the prognosis in this usually fatal disease. We studied 103 patients with mycosis fungoides, who, after complete staging, were randomly assigned to receive either combination therapy, consisting of 3000 cGy of electron-beam radiation to the skin combined with parenteral chemotherapy with cyclophosphamide, doxorubicin, etoposide, and vincristine (n = 52) or sequential topical treatment (n = 51). The prognostic factors were well balanced in the two groups. Combined therapy produced considerable toxicity: 12 patients required hospitalization for fever and transient neutropenia, 5 had congestive heart failure, and 2 were later found to have acute nonlymphocytic leukemia. Patients receiving combined therapy had a significantly higher rate of complete response, documented by biopsy, than patients receiving conservative therapy (38 percent vs. 18 percent; P = 0.032). After a median follow-up of 75 months, however, there was no significant difference between the treatment groups in disease-free or overall survival. We conclude that early aggressive therapy with radiation and chemotherapy does not improve the prognosis for patients with mycosis fungoides as compared with conservative treatment beginning with sequential topical therapies.

    A 69-year-old male was admitted to our hospital because of dysphagia. The diagnosis was double cancer with hypopharyngeal and esophageal carcinoma from upper gastrointestinal endoscopic examination. Pathological examinations of the double cancer revealed moderately-differentiated squamous cell carcinoma. Computed tomography(CT)of the neck and abdomen showed metastases of the right neck and cardiac lymph nodes. Clinical stagings of the double cancer were Stage III (T1, N1, M0)in hypopharyngeal carcinoma and Stage III (T3, N1, M0)in esophageal carcinoma, respectively. He received radiation therapy in combination with chemotherapy using docetaxel(DOC), 5-fluorouracil (5-FU)and nedaplatin(CDGP). After this combination chemoradiation therapy(CRT), the adverse event was grade 2 in leucopenia and grade 2 in gastrointestinal toxicity. Repeated macroscopic and histological examinations after CRT revealed disappearance of the hypopharyngeal and advanced esophageal carcinoma with lymph node metastasis, leading to a complete response(CR). He had maintained CR for the 20 months since undergoing CRT. This combination chemotherapy of DOC, 5-FU and CDGP with radiation may well be effective and tolerable for patients with double cancer of hypopharyngeal and esophageal carcinoma.

    Neo-adjuvant chemoradiotherapy is the gold standard of the treatment of advanced oesophageal squamous cell carcinoma. The role of surgery L. chemoradiotherapy is still debated. Feasibility of curative resection depends on dose of radiotherapy, morbi-mortality rates, and nutrition status at the end of the protocol especially for non-responders patients. Adding surgery to radio-chemotherapy improves local tumour control but does not increase overall survival of patients with advanced oesophageal squamous cell carcinoma. According to the two randomized trials published on the subject, surgery is not recommended after chemoradiotherapy for responders. Recommendations of French National Thesaurus are: exclusive chemoradiotherapy as reference, oesophagectomy for residual tumour as alternative for operable patients. Surgery may be proposed for selected non-responders patients and some complete pathology response in expert center. (author)

    Purpose: A radio-guided surgery technique with beta- -emitting radio-tracers was suggested to overcome the effect of the large penetration of gamma radiation. The feasibility studies in the case of brain tumors and abdominal neuro-endocrine tumors were based on simulations starting from PET images with several underlying assumptions. This paper reports, as proof-of-principle of this technique, an ex-vivo test on a meningioma patient. This test allowed to validate the whole chain, from the evaluation of the SUV of the tumor, to the assumptions on the bio-distribution and the signal detection. Methods: A patient affected by meningioma was administered 300 MBq of 90Y-DOTATOC. Several samples extracted from the meningioma and the nearby Dura Mater were analyzed with a beta- probe designed specifically for this radio-guided surgery technique. The observed signals were compared both with the evaluation from the histology and with the Monte Carlo simulation. Results: we obtained a large signal on the bulk tumor (105...

    Purpose: To prospectively investigate the efficacy and toxicity of accelerated hypofractionated thoracic radiation therapy (HypoTRT) combined with concurrent chemotherapy in the treatment of limited-stage small-cell lung cancer (LS-SCLC), with the hypothesis that both high radiation dose and short radiation time are important in this setting. Methods and Materials: Patients with previously untreated LS-SCLC, Eastern Cooperative Oncology Group performance status of 0 to 2, and adequate organ function were eligible. HypoTRT of 55 Gy at 2.5 Gy per fraction over 30 days was given on the first day of the second or third cycle of chemotherapy. An etoposide/cisplatin regimen was given to 4 to 6 cycles. Patients who had a good response to initial treatment were offered prophylactic cranial irradiation. The primary endpoint was the 2-year progression-free survival rate. Results: Fifty-nine patients were enrolled from July 2007 through February 2012 (median age, 58 years; 86% male). The 2-year progression-free survival rate was 49.0% (95% confidence interval [CI] 35.3%-62.7%). Median survival time was 28.5 months (95% CI 9.0-48.0 months); the 2-year overall survival rate was 58.2% (95% CI 44.5%-71.9%). The 2-year local control rate was 76.4% (95% CI 63.7%-89.1%). The severe hematologic toxicities (grade 3 or 4) were leukopenia (32%), neutropenia (25%), and thrombocytopenia (15%). Acute esophagitis and pneumonitis of grade ≥3 occurred in 25% and 10% of the patients, respectively. Thirty-eight patients (64%) received prophylactic cranial irradiation. Conclusion: Our study showed that HypoTRT of 55 Gy at 2.5 Gy per fraction daily concurrently with etoposide/cisplatin chemotherapy has favorable survival and acceptable toxicity. This radiation schedule deserves further investigation in LS-SCLC.

    Purpose: To determine how chemotherapy agents affect radiation dose parameters that correlate with acute hematologic toxicity (HT) in patients treated with pelvic intensity modulated radiation therapy (P-IMRT) and concurrent chemotherapy. Methods and Materials: We assessed HT in 141 patients who received P-IMRT for anal, gynecologic, rectal, or prostate cancers, 95 of whom received concurrent chemotherapy. Patients were separated into 4 groups: mitomycin (MMC) + 5-fluorouracil (5FU, 37 of 141), platinum ± 5FU (Cis, 32 of 141), 5FU (26 of 141), and P-IMRT alone (46 of 141). The pelvic bone was contoured as a surrogate for pelvic bone marrow (PBM) and divided into subsites: ilium, lower pelvis, and lumbosacral spine (LSS). The volumes of each region receiving 5-40 Gy were calculated. The endpoint for HT was grade ≥3 (HT3+) leukopenia, neutropenia or thrombocytopenia. Normal tissue complication probability was calculated using the Lyman-Kutcher-Burman model. Logistic regression was used to analyze association between HT3+ and dosimetric parameters. Results: Twenty-six patients experienced HT3+: 10 of 37 (27%) MMC, 14 of 32 (44%) Cis, 2 of 26 (8%) 5FU, and 0 of 46 P-IMRT. PBM dosimetric parameters were correlated with HT3+ in the MMC group but not in the Cis group. LSS dosimetric parameters were well correlated with HT3+ in both the MMC and Cis groups. Constrained optimization (0chemotherapy received. Patients receiving P-IMRT ± 5FU have better bone marrow tolerance than those receiving irradiation concurrent with either Cis or MMC. Treatment with MMC has a lower TD{sub 50} and more steeply rising normal tissue complication probability curve compared with treatment with Cis. Dose tolerance of PBM and the LSS subsite may be lower for

    Neoadjuvant chemotherapy generally induces significant changes in the pathological extent of disease and challenges the standard indications of adjuvant postmastectomy radiation therapy. We retrospectively evaluated the impact of postmastectomy radiation therapy in breast cancer patients with negative lymph nodes (pN0) after neoadjuvant chemotherapy. Among 1054 breast cancer patients treated with neoadjuvant chemotherapy in our institution between 1990 and 2004, 134 patients had pN0 status after neoadjuvant chemotherapy and mastectomy. Demographic data, tumor characteristics, metastatic sites, and treatments were prospectively recorded. The impact of postmastectomy radiation therapy on locoregional recurrence-free survival and overall survival was evaluated by multivariate analysis including known prognostic factors. Among 134 eligible patients, 78 patients (58.2%) received postmastectomy radiation therapy, and 56 patients (41.8%) did not. With a median follow-up time of 91.4 months, the 10-year locoregional recurrence-free survival and overall survival rates were 96.2% and 77.2% with postmastectomy radiation therapy and 86.8% and 87.7% without radiation therapy, respectively (no significant difference). In multivariate analysis, there was a trend towards poorer overall survival among patients who did not have a pathologically complete primary tumour response after neoadjuvant chemotherapy (hazard ratio [HR], 6.65; 95% CI, 0.82-54.12; P=0.076). Postmastectomy radiation therapy had no effect on either locoregional recurrence-free survival (HR, 0.37; 95% CI, 0.09-1.61; P=0.18) or overall survival (HR, 2.06; 95% CI, 0.71-6; P=0.18). There was a trend towards poorer overall survival among patients who did not have pathologically complete in-breast tumour response after neoadjuvant chemotherapy (HR, 6.65; 95% CI, 0.82-54.12; P=0.076). This retrospective study showed no increase in the risk of distant metastasis, locoregional recurrence or death when postmastectomy

    Estrogen receptor (ER) negative (-) breast cancer (BC) patients have better tumor response rates than ER-positive (+) patients after neoadjuvant chemotherapy (NCT). We conducted a retrospective review using the institutional database "Biomatrix" to assess the value of quantitative ER status in predicting tumor response at surgery and to identify potential predictors of survival outcomes. Univariate followed by multivariable regression analyses were conducted to assess the association between quantitative ER and tumor response assessed as tumor size reduction and pathologic complete response (pCR). Predictors of recurrence-free survival (RFS) were identified using a cox proportional hazards model (CPH). A log-rank test was used to compare RFS between groups if a significant predictor was identified. 304 patients were included with a median follow-up of 43.3 months (Q1-Q3 28.7-61.1) and a mean age of 49.7 years (SD 10.9). Quantitative ER was inversely associated with tumor size reduction and pCR (OR 0.99, 95% CI 0.99-1.00, p = 0.027 and 0.98 95% CI 0.97-0.99, p Quantitative ER status is inversely associated with tumor response in BC patients treated with NCT. A cut-off of 60 and 80% predicts best the association with tumor size reduction and pCR, respectively. Therefore, patients with an ER status higher than the cut-off might benefit from a neoadjuvant endocrine therapy approach. Patients with pCR had better survival outcomes independently of their tumor phenotype. Further prospective studies are needed to validate the clinical utility of quantitative ER as a predictive marker of tumor response.

    Objective: Early laryngeal cancer is usually treated with either transoral laser surgery or radiation therapy. The quality of voice achieved with these treatments has not been compared in a randomized trial. Methods and Materials: Male patients with carcinoma limited to 1 mobile vocal cord (T1aN0M0) were randomly assigned to receive either laser surgery (n=32) or external beam radiation therapy (n=28). Surgery consisted of tumor excision with a CO{sub 2} laser with the patient under general anaesthesia. External beam radiation therapy to the larynx was delivered to a cumulative dose of 66 Gy in 2-Gy daily fractions over 6.5 weeks. Voice quality was assessed at baseline and 6 and 24 months after treatment. The main outcome measures were expert-rated voice quality on a grade, roughness, breathiness, asthenia, and strain (GRBAS) scale, videolaryngostroboscopic findings, and the patients' self-rated voice quality and its impact on activities of daily living. Results: Overall voice quality between the groups was rated similar, but voice was more breathy and the glottal gap was wider in patients treated with laser surgery than in those who received radiation therapy. Patients treated with radiation therapy reported less hoarseness-related inconvenience in daily living 2 years after treatment. Three patients in each group had local cancer recurrence within 2 years from randomization. Conclusions: Radiation therapy may be the treatment of choice for patients whose requirements for voice quality are demanding. Overall voice quality was similar in both treatment groups, however, indicating a need for careful consideration of patient-related factors in the choice of a treatment option.

    The present study aimed to determine the toxicity and efficacy of 4 courses of anthracyclines-taxane (AT) chemotherapy followed by radiation therapy (XRT) concurrent with cyclophosphamide, methotrexate and 5-fluorouracil (CMF) in surgically resected axillary node-positive (N+) breast cancer. A total of 200 women with N+ breast cancer were treated with adriamycin and docetaxel followed by XRT concurrent with six courses of CMF. Two courses of dose-dense chemotherapy with ifosfamide, carboplatin and etoposide, supported by pegfilgrastim, were administered to patients with >5 histologically confirmed axillary lymph node metastases and patients with triple-negative disease. Additional treatments included 1 year of trastuzumab in human epidermal growth factor receptor 2-positive patients, 5 years of a luteinizing hormone-releasing hormone analogue in premenopausal women and 5 years of an aromatase inhibitor (AI) in estrogen receptor-positive (ER+) patients. The mean number of positive axillary lymph nodes was 4.4 (range, 2-37), 52% of the patients were premenopausal, 74% were ER+ and 26% had triple-negative disease. After a median follow-up of 73 months, grade 2 and 3 hematological toxicity was observed in 20% of the patients. The 10-year disease-free survival (DFS) and overall survival (OS) rates were 73 and 77%, respectively. There was no significant difference in DFS between ER+ and estrogen receptor-negative (ER-) patients (P>0.05), whereas the OS was better in ER+ vs. ER- patients (P<0.05) and in premenopausal vs. postmenopausal patients (P<0.005). In conclusion, induction AT concurrent CMF and XRT and dose-dense chemotherapy followed by AI in N+ high-risk breast cancer was associated with a low level of systemic and late cardiac toxicity and excellent local control, DFS and OS.

    Full Text Available The aim of this paper is to report on the challenges associated with identifying disease recurrence following combined modality therapy (CMT for primary lymphoma of the tibia in which an intramedullary nail has been placed. A patient with primary bone lymphoma (PBL was treated with CMT (chemotherapy and radiation therapy. After a complete response, he has been followed for eighteen months by physical exam and radiographic imaging. Despite persistent increased tracer accumulation at the original site, he has no proven recurrence. Literature review showed a small number of retrospective, single institution reviews detailing clinical experience and expected outcome in patients treated with PBL limited to one bony site of disease. PBL presents a treatment challenge, particularly when a weight-bearing long bone is diffusely involved and followup is complicated after placement of stabilizing hardware. Close coordination of the oncology team and diagnostic radiology is required to ensure optimal outcome.

    43 patients with stage III NSCLC (non-small cell lung cancer) entered a phase II study aimed at evaluating the toxicity and the activity of a combined modality programme including an accelerated split-course schedule (type B) of thoracic radiation therapy and a combination chemotherapy with vinorelbine and carboplatin. An objective response was achieved in 18/42 evaluable patients (5 complete and 13 partial responses), for an overall response rate of 43% (95% confidence interval, 28-58%). Four complete responses had a duration which exceeded 16 months. Treatment was well tolerated; grade III myelotoxicity occurred in only 14% of patients and treatment was delayed in only 2 cases because of grade 3 oesophagitis. Both tolerability and efficacy data suggest that this regimen holds promise for the treatment of patients with stage III NSCLC. (author).

    Purpose: A subset of patients with oropharyngeal squamous cell carcinoma (OP-SCC) managed with transoral robotic surgery (TORS) and postoperative radiation therapy (PORT) developed soft tissue necrosis (STN) in the surgical bed months after completion of PORT. We investigated the frequency and risk factors. Materials and Methods: This retrospective analysis included 170 consecutive OP-SCC patients treated with TORS and PORT between 2006 and 2012, with >6 months' of follow-up. STN was defined as ulceration of the surgical bed >6 weeks after completion of PORT, requiring opioids, biopsy, or hyperbaric oxygen therapy. Results: A total of 47 of 170 patients (28%) had a diagnosis of STN. Tonsillar patients were more susceptible than base-of-tongue (BOT) patients, 39% (41 of 104) versus 9% (6 of 66), respectively. For patients with STN, median tumor size was 3.0 cm (range 1.0-5.6 cm), and depth of resection was 2.2 cm (range 1.0-5.1 cm). Median radiation dose and dose of fraction to the surgical bed were 6600 cGy and 220 cGy, respectively. Thirty-one patients (66%) received concurrent chemotherapy. Median time to STN was 2.5 months after PORT. All patients had resolution of STN after a median of 3.7 months. Multivariate analysis identified tonsillar primary (odds ratio [OR] 4.73, P=.01), depth of resection (OR 3.12, P=.001), total radiation dose to the resection bed (OR 1.51 per Gy, P<.01), and grade 3 acute mucositis (OR 3.47, P=.02) as risk factors for STN. Beginning May 2011, after implementing aggressive avoidance of delivering >2 Gy/day to the resection bed mucosa, only 8% (2 of 26 patients) experienced STN (all grade 2). Conclusions: A subset of OP-SCC patients treated with TORS and PORT are at risk for developing late consequential surgical bed STN. Risk factors include tonsillar location, depth of resection, radiation dose to the surgical bed, and severe mucositis. STN risk is significantly decreased with carefully avoiding a radiation dosage of >2 Gy/day to

    The variety of treatment options for cancer patients has increased significantly in recent years. Not only do we combine radiation with surgery and chemotherapy, new therapeutic approaches such as immunotherapy and targeted therapies are starting to play a bigger role. Physics has made significant contributions to radiation therapy treatment planning and delivery. In particular, treatment plan optimization using inverse planning techniques has improved dose conformity considerably. Furthermore, medical physics is often the driving force behind tumor control and normal tissue complication modeling. While treatment optimization and outcome modeling does focus mainly on the effects of radiation, treatment modalities such as chemotherapy are treated independently or are even neglected entirely. This review summarizes the published efforts to model combined modality treatments combining radiation and chemotherapy. These models will play an increasing role in optimizing cancer therapy not only from a radiation and drug dosage standpoint, but also in terms of spatial and temporal optimization of treatment schedules.

Methods Fifty-six patients underwent chemotherapy after surgery for lung cancer were divided into enteral nutrition support (ENS) group and ordinary diet (OD) group by random. The nutritional evaluation and the biochemical indicators of all the patients were measured before and after the treatment. The follow-up survey lasted one month. Results There was no significent difference between each target of the ENS group and the OD group before the treatment(P>0.05), so two grougs were commeasurable. But compared the average differential value of each target before and after the treatment of the ENS groups with the OD groups, there was significance difference(P<0.05). Conclusion Enteral nutrition support on patients underwent chemotherapy after surgery for lung cancer can obviously improve the nutritional situation, enhance the immunity function and the tolerance of the chemotherapy. It can help the patients to cross the chemotherapy time safely.

    In order to treat the peritoneal carcinomatosis from abdominal neoplasms has been recently proposed complete peritonectomy associated with IntraPeritoneal Hyperthermic Chemotherapy (IHPC). Estimate of postoperative morbidity and mortality and short-term outcome. Twenty-four patients with peritoneal carcinomatosis or positive cytology at peritoneal washing were treated in our Department from January 2005 to October 2007. Primary tumor was ovarian carcinoma in ten patients: four cases presented peritoneal surface malignancies (PSM) after any time from hysteroadnexectomy related to primary tumor, six cases synchronous PSM. Primary tumor was gastric cancer in seven patients: the peritoneal washing was positive in four cases and, during follow-up period after gastrectomy, other two cases presented PSM. One patient was previously treated with ovariectomy for ovaric mass that resulted a Krukenberg's tumor of gastric cancer. Primary tumor was pseudomixoma peritonei in four patients; cytoreductive surgery and IHPC was carried as first line therapy in only one patient. Three patients were previously treated for colon carcinoma. IHPC was carried out through abdominopelvic cavity for 60 minutes using a closed abdomen technique. The drugs used were Mitomycin C (3.3 mg/m2/L) and Cisplatin (25 mg/m2/L). The intracavitary mean temperature was 41.8 degrees C. The mean Peritoneal Cancer Index (PCI) was 14. Postoperative major complications occurred in 7 cases (28%), postoperative minor complications occurred in 8 cases (32%). No patients died in the postoperative period. Mean hospital staying was 11.5 days ( 6-35 days). After a median follow-up of 8 months (range 2-34), 14 (58%) patients are alive and 13 are disease free. Our experience is consistent with other studies for the high rate of postoperative morbidity associated with treatment, but we achieved best results on mortality and post-operative staying. CRS associated with IHPC is a good therapeutic option especially in ovaric

    Full Text Available Abstract Background Primary treatment of carcinoma of the oro-/hypopharynx or larynx may consist of combined platinum-containing chemoradiotherapy. In order to improve clinical outcome (i.e. local control/overall survival, combined therapy is intensified by the addition of the EGFR inhibitor cetuximab (Erbitux®. Radiation therapy (RT is carried out as intensity-modulated RT (IMRT to avoid higher grade acute and late toxicity by sparing of surrounding normal tissues. Methods/Design The REACH study is a prospective phase II study combining chemoradiotherapy with carboplatin/5-Fluorouracil (5-FU and the monoclonal epidermal growth factor-receptor (EGFR antibody cetuximab (Erbitux® as intensity-modulated radiation therapy in patients with locally advanced squamous-cell carcinomas of oropharynx, hypopharynx or larynx. Patients receive weekly chemotherapy infusions in the 1st and 5th week of RT. Additionally, cetuximab is administered weekly throughout the treatment course. IMRT is delivered as in a classical concomitant boost concept (bid from fraction 16 to a total dose of 69,9 Gy. Discussion Primary endpoint of the trial is local-regional control (LRC. Disease-free survival, progression-free survival, overall survival, toxicity, proteomic and genomic analyses are secondary endpoints. The aim is to explore the efficacy as well as the safety and feasibility of this combined radioimmunchemotherapy in order to improve the outcome of patients with advanced head and neck cancer.

    Persistent pathologic mediastinal nodal involvement after induction chemotherapy and surgical resection is a negative prognostic factor for stage III-N2 non-small cell lung cancer patients. This population has high rates of local-regional failure and distant failure, yet the effectiveness of additional therapies is not clear. We assessed the role of consolidative therapies (postoperative radiation therapy and chemotherapy) for such patients. In all, 179 patients with stage III-N2 non-small cell lung cancer at MD Anderson Cancer Center were treated with induction chemotherapy followed by surgery from 1998 through 2008; 61 patients in this cohort had persistent, pathologically confirmed, mediastinal nodal disease, and were treated with postoperative radiation therapy. Local-regional failure was defined as recurrence at the surgical site or lymph nodes (levels 1 to 14, including supraclavicular), or both. Overall survival was calculated using the Kaplan-Meier method, and survival outcomes were assessed by log rank tests. Univariate and multivariate Cox proportional hazards models were used to identify factors influencing local-regional failure, distant failure, and overall survival. All patients received postoperative radiation therapy after surgery, but approximately 25% of the patients also received additional chemotherapy: 9 (15%) with concurrent chemotherapy, 4 (7%) received adjuvant sequential chemotherapy, and 2 (3%) received both. Multivariate analysis indicated that additional postoperative chemotherapy significantly reduced distant failure (hazard ratio 0.183, 95% confidence interval: 0.052 to 0.649, p=0.009) and improved overall survival (hazard ratio 0.233, 95% confidence interval: 0.089 to 0.612, p=0.003). However, additional postoperative chemotherapy had no affect on local-regional failure. Aggressive consolidative therapies may improve outcomes for patients with persistent N2 disease after induction chemotherapy and surgery. Copyright © 2012 The

    Full Text Available Background and Objectives: Acute hematological toxicities are an important cause of morbidity in patients receiving concurrent chemoradiation to pelvis in carcinoma cervix. The objective of this study was to evaluate the role of intensity-modulated radiotherapy (IMRT in reducing the dose to the bone marrow as compared with three-dimensional conformal radiotherapy (3DCRT and hence its impact on reducing the acute hematological toxicities. Materials and Methods: Eleven consecutive patients treated with IMRT and 12 patients treated with 3DCRT to the whole pelvis along with concurrent chemotherapy were selected. Bone marrow was delineated. V10 Gy, V20 Gy, V95%, and Dmean of bone marrow were recorded. Weekly blood counts were recorded and graded as per Common Terminology Criteria version 4.0 for all the patients. Results: The dose to the bone marrow V20 Gy was 206.78 ± 57.10 cc (75% and 251.70 ± 40.45 cc (91% for IMRT and 3DCRT, respectively (P = 0.04 and V95% was 23.30 ± 8.34% and 46.76 ± 6.71% for IMRT and 3DCRT, respectively (P = 0.001. The grade of toxicities during each week did not show the difference in either arm. However, the total count and Neutrophil counts during the 2nd week showed statistical significance between IMRT and 3DCRT. Conclusion: IMRT significantly reduces the dose to the bone marrow as compared to 3DCRT. The reduction of the dose did not translate into a decrease in acute hematological toxicities. Concurrent platinum-based chemotherapy is the probable cause for the hematological toxicities.

    This study evaluates the anorectal and genitourinary function of patients treated by preoperative short-term radiotherapy (RT) or chemoradiotherapy (CRT) followed by surgery and surgery alone for rectal cancer. For this study, a total of 613 patients, who were identified from a prospective rectal cancer database, underwent anterior resection of the rectum between October 2001 and December 2007. Standardized questionnaires were used to determine fecal incontinence, urinary, and sexual function. Relevant clinical variables were evaluated using univariate and multivariate analyses. Independent predictors of functional outcome were identified by a binary logistic regression analysis. The data of 263 (43 %) patients were available for analysis. On multivariate analysis, neoadjuvant RT (P < 0.01) and low anterior resection (LAR) (P = 0.049) were associated with fecal incontinence. In univariate analysis, fecal incontinence was linked to preoperative neoadjuvant treatment (RT and/or CRT vs. LAR) (P < 0.01). The hazard ratio for developing fecal incontinence was 3.3 (1.6-6.8) for patients who received RT. One hundred twenty-five patients (51.2 %) experienced urinary incontinence following surgery, the majority of whom were female (P < 0.01). On univariate analysis, male sexual function was associated with age (P < 0.01), ASA class (P = 0.01) and LAR (P = 0.01). Multimodal therapy of low rectal cancer increases the incidence of fecal incontinence and negatively affects sexual function. The potential benefits of RT or CRT need to be balanced against the risk of increased bowel dysfunction when determining the appropriate treatment for individual patients with rectal cancer.

    Full Text Available Gastropericardial fistula is generally associated with benign gastric diseases and is an uncommon complication of gastric adenocarcinoma. Pericarditis and cardiac tamponade are the ultimate outcome, with extremely high mortality rates. We report a 47-year-old man with gastric adenocarcinoma who had completed radiotherapy and was on scheduled chemotherapy, who presented with fever and chest pain. Gastric adenocarcinoma complicated with gastropericardial fistula and Candida albicans pericarditis were diagnosed and treated successfully with conservative management. Initial chest radiography and computed tomography (CT revealed no evident pericardial air or fluid. However, follow-up panendoscopy 2 weeks later revealed a malignant ulcer with a fistula opening over the lesser curvature of the high body of the stomach. Subsequent chest radiography and CT revealed pneumopericardium with fluid accumulation. Emergent CT-guided pericardial drainage was performed. The fluid was positive for Candida albicans. Total parenteral nutrition and antifungal therapy were administered. The patient refused surgical intervention and survived with medical management alone. This case demonstrates that first, panendoscopy may be safely performed in patients with gastropericardial fistula without significant risk of cardiac tamponade; second, although early diagnosis of gastropericardial fistula is generally important, delayed recognition may not lead to devastating outcomes even in the absence of surgical intervention.

    Purpose: To describe the anatomic distribution of regionally recurrent disease in patients with stage III melanoma in the axilla after curative-intent surgery with and without adjuvant radiation therapy. Methods and Materials: A single-institution, retrospective analysis of a prospective database of 277 patients undergoing curative-intent treatment for stage III melanoma in the axilla between 1992 and 2012 was completed. For patients who received radiation therapy and those who did not, patterns of regional recurrence were analyzed, and univariate analyses were performed to assess for potential factors associated with location of recurrence. Results: There were 121 patients who received adjuvant radiation therapy because their clinicopathologic features conferred a greater risk of regional recurrence. There were 156 patients who received no radiation therapy. The overall axillary control rate was 87%. There were 37 patients with regional recurrence; 17 patients had received adjuvant radiation therapy (14%), and 20 patients (13%) had not. The likelihood of in-field nodal recurrence was significantly less in the adjuvant radiation therapy group (P=.01) and significantly greater in sites adjacent to the axilla (P=.02). Patients with high-risk clinicopathologic features who did not receive adjuvant radiation therapy also tended to experience in-field failure rather than adjacent-field failure. Conclusions: Patients who received adjuvant radiation therapy were more likely to experience recurrence in the adjacent-field regions rather than in the in-field regions. This may not simply reflect higher-risk pathology. Using this data, it may be possible to improve outcomes by reducing the number of adjacent-field recurrences after adjuvant radiation therapy.

    The objective of this work was to assess the incidence of radiological changes compatible with radiation-induced lung damage as determined by computed tomography (CT), and subsequently calculate the dose effect factors (DEF) for specified chemotherapeutic regimens. Radiation treatments were administered once daily, 5 days-per-week. Six clinical protocols were evaluated: ABVD (adriamycin, bleomycin, vincristine, and DTIC) followed by 35 Gy in 20 fractions; MOPP (nitrogen mustard, vincristine, procarbazine, and prednisone) followed by 35 Gy in 20; MOPP/ABVD followed by 35 Gy in 20; CAV (cyclophosphamide, adriamycin, and vincristine) followed by 25 Gy in 10; and 5-FU (5-fluorouracil) concurrent with either 50-52 Gy in 20-21 or 30-36 Gy in 10-15 fractions. CT examinations were taken before and at predetermined intervals following radiotherapy. CT evidence for the development of radiation-induced damage was defined as an increase in lung density within the irradiated volume. The radiation dose to lung was calculated using a CT-based algorithm to account for tissue inhomogeneities. Different fractionation schedules were converted using two isoeffect models, the estimated single dose (ED) and the normalized total dose (NTD). The actuarial incidence of radiological pneumonitis was 71% for the ABVD, 49% for MOPP, 52% for MOPP/ABVD, 67% for CAV, 73% for 5-FU radical, and 58% for 5-FU palliative protocols. Depending on the isoeffect model selected and the method of analysis, the DEF was 1.11-1.14 for the ABVD, 0.96-0.97 for the MOPP, 0.96-1.02 for the MOPP/ABVD, 1.03-1.10 for the CAV, 0.74-0.79 for the 5-FU radical, and 0.94 for the 5-FU palliative protocols. DEF were measured by comparing the incidence of CT-observed lung damage in patients receiving chemotherapy and radiotherapy to those receiving radiotherapy alone. The addition of ABVD or CAV appeared to reduce the tolerance of lung to radiation. 40 refs., 3 figs., 3 tabs.

    OBJECTIVE: To evaluate ipsilateral breast tumor recurrence after breast-conserving surgery for locally advanced breast cancer. METHODS: A retrospective observational cohort study was performed in patients with locally advanced breast cancer submitted to breast-conserving surgery after neoadjuvant chemotherapy based on an adriamycin-cyclophosphamide-paclitaxel regimen. We evaluated the clinical, pathologic, immunohistochemistry, and surgical factors that contribute to ipsilateral breast tumor recurrence and locoregional recurrence. A Kaplan-Meier analysis and Cox model were used to evaluate the main factors related to disease-free survival. RESULTS: Of the 449 patients who received neoadjuvant chemotherapy, 98 underwent breast-conserving surgery. The average diameter of the tumors was 5.3 cm, and 87.2% reached a size of up to 3 cm. Moreover, 86.7% were classified as clinical stage III, 74.5% had T3-T4 tumors, 80.5% had N1-N2 axilla, and 89.8% had invasive ductal carcinoma. A pathologic complete response was observed in 27.6% of the tumors, and 100.0% of samples had free margins. The 5-year actuarial overall survival rate was 81.2%, and the mean follow-up was 72.8 months. The rates of ipsilateral breast tumor recurrence and locoregional recurrence were 11.2% and 15.3%, respectively. Multifocal morphology response was the only factor related to ipsilateral breast tumor recurrence disease-free survival (p=0.04). A multivariate analysis showed that the pathologic response evaluation criteria in solid tumors (RECIST)-breast cutoff was the only factor related to locoregional recurrence disease-free survival (p=0.01). CONCLUSIONS: Breast-conserving surgery is a safe and effective therapy for selected locally advanced breast tumors. PMID:28355358

    Purpose: to prospectively assess health-related quality of life (HR-QoL) in women after conserving surgery for breast cancer during/after postoperative 3-D radiotherapy. Patients and methods: 109 consecutively treated patients were analyzed. HR-QoL was assessed at initiation (t1), end (t2), and 6 weeks after radiotherapy (t3) using the EORTC modules QLQ-C30/BR23. Patients were divided into three therapy groups. Group I comprised 41 patients (radiotherapy and adjuvant chemotherapy), group II 45 patients (radiotherapy and adjuvant hormonal therapy), and group III 23 patients (radiotherapy alone). Reliability was tested. Scale means were calculated. Univariate (ANOVA) and multivariate (MANCOVA) analyses were performed. Results: reliability testing revealed mean Cronbach's {alpha} > 0.70 at all measurement points. ANOVA/MANCOVA statistics revealed significantly better HR-QoL for patients in group II versus I. Patients receiving radiotherapy alone (group III) showed the best results in HR-QoL. However, scale mean differences between groups II and III were not significant. Conclusion: HR-QoL measurement using EORTC instruments during/after radiotherapy is reliable. Adjuvant chemotherapy significantly lowered HR-QoL versus hormones or radiotherapy alone. Chemotherapy patients did not recover longitudinally (from t1 to t3). (orig.)

    The aim of this review is to address the current status of adjuvant chemotherapy alone in early-stage cervical cancer treatments in the literature. At present, the therapeutic effect of adjuvant chemotherapy alone after radical surgery (RS) has not yet been established, and radiation therapy (RT) or concurrent chemoradiotherapy (CCRT) is recommended as the standard adjuvant therapy after RS for early-stage cervical cancer in various guidelines. The main purpose of adjuvant therapy after RS, however, should be to reduce extrapelvic recurrence rather than local recurrence, although adjuvant RT or CCRT has survival benefits for patients with intermediate- or high-risk factors for recurrence. Moreover, several studies reported that adjuvant therapies including RT were associated with a higher incidence of complications, such as lymphedema, bowel obstruction and urinary disturbance, and a lower grade of long-term quality of life (QOL) or sexual functioning than adjuvant chemotherapy alone. The effect of adjuvant chemotherapy alone for early-stage cervical cancer with intermediate- or high-risk factors for recurrence were not fully investigated in prospective studies, but several retrospective studies suggest that the adjuvant effects of chemotherapy alone are at least similar to that of RT or CCRT in terms of recurrence rate, disease-free survival, or overall survival (OS) with lower incidence of complications. Whereas cisplatin based combination regimens were used in these studies, paclitaxel/cisplatin (TP) regimen, which is currently recognized as a standard chemotherapy regimen for patients with metastatic, recurrent or persistent cervical cancer by Gynecologic Oncology Group (GOG), had also survival benefit as an adjuvant therapy. Therefore, it may be worth considering a prospective randomized controlled trial (RCT) of adjuvant chemotherapy alone using TP regimen versus adjuvant RT as an alternative adjuvant therapy. Because early-stage cervical cancer is a curable

    A 67-year-old man who had been treated three and a half years ago with chemoradiotherapy using concurrent low-dose 5-FU continuous infusion for advanced esophageal cancer (T4N1M0) developed massive unilateral pleural effusion and pericardial effusion with no evidence of tumor recurrence. The pleural fluid was a serohemorrhagic exudate without malignant cells and bacterial infection. The pleural and pericardial effusion were remarkably improved after chest tube drainage and pleurodesis. Radiation-induced pleuritis and pericarditis were considered to be the possible cause of massive pleural and pericardial effusion. (author)

    l-Deprenyl (R-(-)-deprenyl, selegiline) is an inhibitor of monoamine oxidase-B (MAO-B) that is known to protect nerve cells from a variety of chemical and physical insults. As apoptosis is a common mechanism of radiation-induced cell death, the effect of l-deprenyl on the survival of cultured cells and tissue explants was studied following exposure to gamma radiation. The results obtained were compared with the effects of the less-selective MAO-B inhibitor pargyline and the MAO-A inhibitor clorgyline. l-Deprenyl at a concentration of 10(-9) M protected the nontumorigenic cell line (HaCaT) and normal human urothelial explants from the effects of cobalt-60 gamma radiation, but did not protect tumorigenic human cell lines HaCaT-ras, HPV-transfected human keratinocytes (HPV-G cells), or PC3. Human bladder carcinoma explants were not protected. Clorgyline showed a smaller protective effect of normal cells, whereas pargyline had no effect. Radiation-induced delayed effects (genomic instability measured as delayed cell death) were prevented in normal cells by l-deprenyl but, interestingly, deprenyl appeared to increase the amount of delayed death in the tumorigenic cell lines. Studies using l-deprenyl prior to the exposure of nonmalignant cells to cisplatin showed that cell death due to this agent was also reduced. Treatment of cultures of nontumorigenic cells with l-deprenyl or clorgyline significantly increased the levels of the protein Bcl-2 following irradiation, but there was no such effect on the already-elevated levels of this protein in the tumour samples. Since the Bcl-2 has been shown to be an inhibitor of apoptosis or programmed cell death, this would imply that the protective effects of l-deprenyl and clorgyline involve activation of antiapoptotic pathways within the normal cell. This hypothesis is supported by data showing reduced levels of apoptosis in HaCAT cells and in normal bladder explant cultures following treatment with l-deprenyl.

    Full Text Available Abstract Background Induction chemotherapy (ICT with docetaxel, cisplatin and fluorouracil (TPF followed by radiotherapy is an effective treatment option for unresectable locally advanced head and neck cancer. This phase I study was designed to investigate the safety and tolerability of a split-dose TPF ICT regimen prior to surgery for locally advanced resectable oral and oropharyngeal cancer. Methods Patients received TPF split on two dosages on day 1 and 8 per cycle for one or three 3-week cycles prior to surgery and postoperative radiotherapy or radiochemotherapy. Docetaxel was escalated in two dose levels, 40 mg/m2 (DL 0 and 30 mg/m2 (DL −1, plus 40 mg/m2 cisplatin and 2000 mg/m2 fluorouracil per week using a 3 +3 dose escalation algorithm. Results Eighteen patients were enrolled and were eligible for toxicity and response. A maximum tolerated dose of 30 mg/m2 docetaxel per week was reached. The most common grade 3+ adverse event was neutropenia during ICT in 10 patients. Surgery reached R0 resection in all cases. Nine patients (50% showed complete pathologic regression. Conclusions A split-dose regime of TPF prior to surgery is feasible, tolerated and merits additional investigation in a phase II study with a dose of 30 mg/m docetaxel per week.

    Radiation has been an effective tool for treating cancer for a long time. Radiation therapy induces DNA damage within cancer cells and destroys their ability to reproduce. Radiation therapy is often combined with other treatments, like surgery and chemotherapy. Here, we describe the effects of radiation and histone deacetylase inhibitor, Trichostain A, on cell cycle regulation in hepatoma cells. Results demonstrate that the treatment of radiation TSA induces cell cycle arrest, thereby stimulating cell death in hepatoma cells. In addition, since different cells or tissues have different reactivity to radiation and TSA, these results might be an indicator for the combination therapy with radiation and drugs in diverse cancers.

    Purpose: Severe (Radiation Therapy Oncology Group [RTOG] grade 3 or greater) esophagitis generally occurs in 15% to 25% of non–small cell lung cancer (NSCLC) patients undergoing concurrent chemotherapy and radiation therapy (CCRT), which may result in treatment breaks that compromise local tumor control and pose a barrier to dose escalation. Here, we report a novel contralateral esophagus-sparing technique (CEST) that uses intensity modulated radiation therapy (IMRT) to reduce the incidence of severe esophagitis. Methods and Materials: We reviewed consecutive patients with thoracic malignancies undergoing curative CCRT in whom CEST was used. The esophageal wall contralateral (CE) to the tumor was contoured as an avoidance structure, and IMRT was used to guide a rapid dose falloff gradient beyond the target volume in close proximity to the esophagus. Esophagitis was recorded based on the RTOG acute toxicity grading system. Results: We identified 20 consecutive patients treated with CCRT of at least 63 Gy in whom there was gross tumor within 1 cm of the esophagus. The median radiation dose was 70.2 Gy (range, 63-72.15 Gy). In all patients, ≥99% of the planning and internal target volumes was covered by ≥90% and 100% of prescription dose, respectively. Strikingly, no patient experienced grade ≥3 esophagitis (95% confidence limits, 0%-16%) despite the high total doses delivered. The median maximum dose, V45, and V55 of the CE were 60.7 Gy, 2.1 cc, and 0.4 cc, respectively, indicating effective esophagus cross-section sparing by CEST. Conclusion: We report a simple yet effective method to avoid exposing the entire esophagus cross-section to high doses. By using proposed CE dose constraints of V45 <2.5 cc and V55 <0.5 cc, CEST may improve the esophagus toxicity profile in thoracic cancer patients receiving CCRT even at doses above the standard 60- to 63-Gy levels. Prospective testing of CEST is warranted.

    OBJECTIVE Vestibular schwannomas (VSs) represent a common indication of Gamma Knife surgery (GKS). While most studies focus on the long-term morbidity and adverse radiation effects (AREs), none describe the acute clinical AREs that might appear on a short-term basis. These types of events are investigated, and their incidence, type, and outcomes are reported in the present paper. METHODS The included patients were treated between July 2010 and March 2016, underwent at least 6 months of follow-up, and presented with a disabling symptom during the first 6 months after GKS that affected their quality of life. The timing of appearance, as well as the type of main symptom and outcome, were noted. The prescribed dose was 12 Gy at the margin. RESULTS Thirty-five (22%) of 159 patients who fulfilled the inclusion criteria had acute clinical AREs. The mean followup period was 30 months (range 6-49.2 months). The mean time of appearance was 37.9 days (median 31 days; range 3-110 days). In patients with de novo symptoms, the more frequent symptoms were vertigo (n = 4; 11.4%) and gait disturbance (n = 3; 8.6%). The exacerbation of a preexisting symptom was more frequently related to hearing loss (n = 10; 28.6%), followed by gait disturbance (n = 7; 20%) and vertigo (n = 3, 8.6%). In the univariate logistic regression analysis, the following factors were statistically significant: age (p = 0.002; odds ratio [OR] 0.96), hearing at baseline by Gardner-Robertson (GR) class (p = 0.006; OR 0.21), pure tone average at baseline (p = 0.006; OR 0.97), and Koos grade at baseline (with Koos Grade I used as a reference) (for Koos Grade II, OR 0.17 and p = 0.002; for Koos Grade III, OR 0.42 and p = 0.05). The following were not statistically significant but showed a tendency toward significance: the number of isocenters (p = 0.06; OR 0.94) and the maximal dose received by the cochlea (p = 0.07; OR 0.74). Fractional polynomial regression analysis showed a nonlinear relationship between the

    Full Text Available Among breast cancer patients treated with neoadjuvant chemotherapy (NAC and mastectomy, locoregional recurrence (LRR rates are unclear in women with ER+ tumors treated with adjuvant endocrine therapy without postmastectomy radiation (PMRT. To determine if PMRT is needed in these patients, we compared LRR rates of patients with ER+ tumors (treated with adjuvant endocrine therapy with women who have non-ER+ tumors. 85 consecutive breast cancer patients (87 breast tumors treated with NAC and mastectomy without PMRT were reviewed. Patients were divided by residual nodal disease (ypN status (ypN+ versus ypN0 and then stratified by receptor subtype. Among ypN+ patients (n=35, five-year LRR risk in patients with ER+, Her2+, and triple negative tumors was 5%, 33%, and 37%, respectively (p=0.02. Among ypN+/ER+ patients, lymphovascular invasion and grade three disease increased the five-year LRR risk to 13% and 11%, respectively. Among ypN0 patients (n=52, five-year LRR risk in patients with ER+, Her2+, and triple negative tumors was 7%, 22%, and 6%, respectively (p=0.71. In women with ER+ tumors and residual nodal disease, endocrine therapy may be sufficient adjuvant treatment, except in patients with lymphovascular invasion or grade three tumors where PMRT may still be indicated.

    To explore the impact of tumor human papillomavirus (HPV) status, comorbidity, polypharmacy, and treatment intensity on overall survival (OS) of elderly oropharyngeal cancer (OPC) patients. All elderly (>70 years) OPC patients receiving definitive (chemo-) radiation therapy in 2000 to 2013 were reviewed. Charlson comorbidity index (CCI, comorbidity alone) and the comorbidity-polypharmacy score (CPS, comorbidity and medication) were calculated. Overall survival was compared between HPV-positive (HPV+) and HPV-negative (HPV-) cohorts. Multivariable analyses (MVA) incorporating either the CCI (MVA-CCI) or the CPS (MVA-CPS) identified survival predictors. Among 231 of 287 patients (80%) with p16 staining, 117 were HPV+ and 114 HPV-. Systemic treatments were administered in 48 patients (21%) (chemotherapy 17; epidermal growth factor receptor inhibitor 31). The distribution of CCI (P=.59), CPS (P=.23), and age (P=.50) were similar between HPV+ versus HPV- cohorts. Median follow-up was 4.3 years. The HPV+ patients had better 5-year OS (57% vs 32%, Ppolypharmacy score, but not CCI, is correlated with OS, especially in HPV+ patients, suggesting the potential importance of assessing polypharmacy in addition to comorbidity burden in this population.

    This retrospective case series evaluates the outcome of 21 dogs with grade II stage 2 mast cell tumour (MCT) treated with adequate local therapy and adjuvant systemic chemotherapy (prednisone, vinblastine and CCNU). The median survival for all dogs was 1359 days (range, 188-2340). Median disease-free interval was 2120 days (149-2325 days). Dogs treated with surgery and chemotherapy had shorter survival (median, 1103 days; 188-2010 days) than those that underwent surgery, radiation therapy and chemotherapy as part of their treatment (median, 2056 days; 300-2340 days). Two patients had local recurrence in the radiation field and four patients had de novo MCT. Distant metastasis was not observed in any dogs. The results of this study suggest that, in the presence of loco-regional lymph node metastasis in grade II MCT, the use of prednisone, vinblastine and CCNU after adequate local-regional therapy can provide a median survival in excess of 40 months.

    Full Text Available Cancer is a leading cause of morbidity and mortality in the modern world. Treatment modalities comprise radiation therapy, surgery, chemotherapy and hormonal therapy. Radiation therapy can be performed by using external or internal radiation therapy. However, each method has its unique properties which undertakes special role in cancer treatment, this question is brought up that: For cancer treatment, whether external radiation therapy is more efficient or internal radiation therapy one? To answer this question, we need to consider principles and structure of individual methods. In this review, principles and application of each method are considered and finally these two methods are compared with each other.

    Carcinoma of the esophagus is classified according to the Union for International Cancer Control (UICC) TNM staging system. The 7th edition of the UICC TNM staging system was published in 2009. This is the first study to compare the prognostic value of the TNM 6th and 7th editions in patients with esophageal carcinoma treated with chemotherapy followed by surgery. Two hundred forty-three patients with esophageal carcinoma were retrospectively selected from two referral centers. All patients received chemotherapy before surgery. Histopathologic data from the resection specimens were retrieved and restaged according to the TNM 7th edition. Disease-specific survival curves were plotted for depth of tumor invasion (ypT), lymph node status (ypN), and ypTNM stage and then compared. Median follow-up after surgery was 2.5 years (range 0.2-9 years). Survival analysis using the log-rank method revealed that there was a significant difference in survival between ypT4 disease and ypT3 disease (P= 0.003), but no difference between ypT0, ypT1, ypT2, and ypT3 categories irrespective of TNM edition used. Survival probability was significantly different between ypN0 and ypN1 (P= 0.001 for TNM 6th and 7th edition), as well as ypN2 and ypN3 (TNM 7th edition, P= 0.004), but not between ypN1 and ypN2 (TNM 7th edition, P= 0.89). Neither the TNM 6th nor 7th edition T staging provides accurate survival probability stratification. However, the advantage of the 7th edition is the introduction of a third tier in survival stratification for patients with nodal involvement. © 2012 Copyright the Authors.

    Radical trachelectomy is the treatment of choice in women with early-stage cervical cancer wishing to preserve fertility. Radical trachelectomy can be performed with a vaginal, abdominal, or laparoscopic/robotic approach. Vaginal radical trachelectomy (VRT) is generally not offered to patients with tumors 2cm or larger because of a high recurrence rate. There are no conclusive recommendations regarding the safety of abdominal radical trachelectomy (ART) or laparoscopic radical trachelectomy (LRT) in such patients. Several investigators have used neoadjuvant chemotherapy in patients with tumors 2 to 4cm to reduce tumor size so that fertility preservation may be offered. However, to our knowledge, no published study has compared outcomes between patients with cervical tumors 2cm or larger who underwent immediate radical trachelectomy and those who underwent neoadjuvant chemotherapy followed by radical trachelectomy. We conducted a literature review to compare outcomes with these 2 approaches. Our main endpoints for evaluation were oncological and obstetrical outcomes. The fertility preservation rate was 82.7%, 85.1%, 89%; and 91.1% for ART (tumors larger than >2cm), ART (all sizes), NACT followed by surgery and VRT (all sizes); respectively. The global pregnancy rate was 16.2%, 24% and 30.7% for ART, VRT, and NACT followed by surgery; respectively. The recurrence rate was 3.8%, 4.2%, 6%, 7.6% and 17% for ART (all sizes), VRT (all sizes), ART (tumors>2cm), NACT followed by surgery, and VRT (tumors>2cm). These outcomes must be considered when offering a fertility sparing technique to patients with a tumor larger than 2cm. Copyright © 2015 Elsevier Inc. All rights reserved.

  7. Radiation-induced valvular heart disease.

    Radiation to the mediastinum is a key component of treatment with curative intent for a range of cancers including Hodgkin's lymphoma and breast cancer. Exposure to radiation is associated with a risk of radiation-induced heart valve damage characterised by valve fibrosis and calcification. There is a latent interval of 10-20 years between radiation exposure and development of clinically significant heart valve disease. Risk is related to radiation dose received, interval from exposure and use of concomitant chemotherapy. Long-term outlook and the risk of valve surgery are related to the effects of radiation on mediastinal structures including pulmonary fibrosis and pericardial constriction. Dose prediction models to predict the risk of heart valve disease in the future and newer radiation techniques to reduce the radiation dose to the heart are being developed. Surveillance strategies for this cohort of cancer survivors at risk of developing significant heart valve complications are required.

    Purpose: To investigate whether high-dose thoracic radiation given twice daily during cisplatin-etoposide chemotherapy for limited small-cell lung cancer (LSCLC) improves survival, acute esophagitis, and local control rates relative to findings from Intergroup trial 0096 (47%, 27%, and 64%). Patients and Methods: Patients were accrued over a 3-year period from 22 US and Canadian institutions. Patients with LSCLC and good performance status were given thoracic radiation to 61.2 Gy over 5 weeks (daily 1.8-Gy fractions on days 1-22, then twice-daily 1.8-Gy fractions on days 23-33). Cisplatin (60 mg/m{sup 2} IV) was given on day 1 and etoposide (120 mg/m{sup 2} IV) on days 1-3 and days 22-24, followed by 2 cycles of cisplatin plus etoposide alone. Patients who achieved complete response were offered prophylactic cranial irradiation. Endpoints included overall and progression-free survival; severe esophagitis (Common Toxicity Criteria v 2.0) and treatment-related fatalities; response (Response Evaluation Criteria in Solid Tumors); and local control. Results: Seventy-two patients were accrued from June 2003 through May 2006; 71 were evaluable (median age 63 years; 52% female; 58% Zubrod 0). Median survival time was 19 months; at 2 years, the overall survival rate was 36.6% (95% confidence interval [CI] 25.6%-47.7%), and progression-free survival 19.7% (95% CI 11.4%-29.6%). Thirteen patients (18%) experienced severe acute esophagitis, and 2 (3%) died of treatment-related causes; 41% achieved complete response, 39% partial response, 10% stable disease, and 6% progressive disease. The local control rate was 73%. Forty-three patients (61%) received prophylactic cranial irradiation. Conclusions: The overall survival rate did not reach the projected goal; however, rates of esophagitis were lower, and local control higher, than projected. This treatment strategy is now one of three arms of a prospective trial of chemoradiation for LSCLC (Radiation Therapy Oncology Group 0538

    Purpose: Comprehensive neck radiation therapy (RT) has been shown to increase cerebrovascular disease (CVD) risk in advanced-stage head-and-neck cancer. We assessed whether more limited neck RT used for early-stage (T1-T2 N0) glottic cancer is associated with increased CVD risk, using the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked database. Methods and Materials: We identified patients ≥66 years of age with early-stage glottic laryngeal cancer from SEER diagnosed from 1992 to 2007. Patients treated with combined surgery and RT were excluded. Medicare CPT codes for carotid interventions, Medicare ICD-9 codes for cerebrovascular events, and SEER data for stroke as the cause of death were collected. Similarly, Medicare CPT and ICD-9 codes for peripheral vascular disease (PVD) were assessed to serve as an internal control between treatment groups. Results: A total of 1413 assessable patients (RT, n=1055; surgery, n=358) were analyzed. The actuarial 10-year risk of CVD was 56.5% (95% confidence interval 51.5%-61.5%) for the RT cohort versus 48.7% (41.1%-56.3%) in the surgery cohort (P=.27). The actuarial 10-year risk of PVD did not differ between the RT (52.7% [48.1%-57.3%]) and surgery cohorts (52.6% [45.2%-60.0%]) (P=.89). Univariate analysis showed an increased association of CVD with more recent diagnosis (P=.001) and increasing age (P=.001). On multivariate Cox analysis, increasing age (P<.001) and recent diagnosis (P=.002) remained significantly associated with a higher CVD risk, whereas the association of RT and CVD remained not statistically significant (HR=1.11 [0.91-1.37,] P=.31). Conclusions: Elderly patients with early-stage laryngeal cancer have a high burden of cerebrovascular events after surgical management or RT. RT and surgery are associated with comparable risk for subsequent CVD development after treatment in elderly patients.

    Purpose: To study the prognostic value of human papillomavirus (HPV) genotypes in patients with advanced cervical cancer treated with radiation therapy (RT) alone or concurrent chemoradiation therapy (CCRT). Methods and Materials: Between August 1993 and May 2000, 327 patients with advanced squamous cell carcinoma of the cervix (International Federation of Gynecology and Obstetrics stage III/IVA or stage IIB with positive lymph nodes) were eligible for this study. HPV genotypes were determined using the Easychip Registered-Sign HPV genechip. Outcomes were analyzed using Kaplan-Meier survival analysis and the Cox proportional hazards model. Results: We detected 22 HPV genotypes in 323 (98.8%) patients. The leading 4 types were HPV16, 58, 18, and 33. The 5-year overall and disease-specific survival estimates for the entire cohort were 41.9% and 51.4%, respectively. CCRT improved the 5-year disease-specific survival by an absolute 9.8%, but this was not statistically significant (P=.089). There was a significant improvement in disease-specific survival in the CCRT group for HPV18-positive (60.9% vs 30.4%, P=.019) and HPV58-positive (69.3% vs 48.9%, P=.026) patients compared with the RT alone group. In contrast, the differences in survival with CCRT compared with RT alone in the HPV16-positive and HPV-33 positive subgroups were not statistically significant (P=.86 and P=.53, respectively). An improved disease-specific survival was observed for CCRT treated patients infected with both HPV16 and HPV18, but these differenced also were not statistically significant. Conclusions: The HPV genotype may be a useful predictive factor for the effect of CCRT in patients with advanced squamous cell carcinoma of the cervix. Verifying these results in prospective trials could have an impact on tailoring future treatment based on HPV genotype.

    To study the impact of postoperative radiation therapy (PORT) on survival in the Adjuvant Navelbine International Trialist Association (ANITA) randomized study of adjuvant chemotherapy. ANITA is a randomized trial of adjuvant cisplatin and vinorelbine chemotherapy vs. observation in completely resected non-small-cell lung carcinoma (NSCLC) Stages IB to IIIA. Use of PORT was recommended for pN+ disease but was not randomized or mandatory. Each center decided whether to use PORT before initiation of the study. We describe here the survival of patients with and without PORT within each treatment group of ANITA. No statistical comparison of survival was performed because this was an unplanned subgroup analysis. Overall, 232 of 840 patients received PORT (33.3% in the observation arm and 21.6% in the chemotherapy arm). In univariate analysis, PORT had a deleterious effect on the overall population survival. Patients with pN1 disease had an improved survival from PORT in the observation arm (median survival [MS] 25.9 vs. 50.2 months), whereas PORT had a detrimental effect in the chemotherapy group (MS 93.6 months and 46.6 months). In contrast, survival was improved in patients with pN2 disease who received PORT, both in the chemotherapy (MS 23.8 vs. 47.4 months) and observation arm (median 12.7 vs. 22.7 months). This retrospective evaluation suggests a positive effect of PORT in pN2 disease and a negative effect on pN1 disease when patients received adjuvant chemotherapy. The results support further evaluation of PORT in prospectively randomized studies in completely resected pN2 NSCLC.

    To test the difference in treatment outcome between breast-conservation surgery with radiation and total mastectomy without radiation, to evaluate the benefits of adjuvant radiotherapy in patients with one to three positive axillary lymph nodes. Using the Severance Hospital Breast Cancer Registry, we divided the study population of T1, T2 and one to three axillary node-positive patients into two groups: breast-conservation surgery with radiation (BCS/RT) and total mastectomy without radiation (TM/no-RT). Data related to locoregional recurrence, distant recurrence, and death were collected, and survival rates were calculated. The study population consisted of 125 patients treated with BCS/RT and 365 patients treated with TM/no-RT. With a median follow-up of 68.4 months, the 10-year locoregional recurrence-free survival rate with BCS/RT and TM/no-RT was 90.5% and 79.2%, respectively (p = 0.056). The 10-year distant recurrence-free survival rate was 78.8% for patients treated with BCS/RT vs. 68.0% for those treated with TM/no-RT (p = 0.012). The 10-years overall survival rate for patients treated with BCT/RT and TM/no-RT was 87.5% and 73.9%, respectively (p = 0.035). After multivariate analysis, patients treated with BCT/RT had better distant recurrence-free survival (hazard ratio [HR], 0.527; 95% confidence interval [CI], 0.297-0.934; p = 0.028), with improving locoregional recurrence-free survival (HR, 0.491; 95% CI, 0.231-1.041; p = 0.064) and overall survival trend (HR, 0.544; 95% CI, 0.277-1.067; p = 0.076). This study provides additional evidence that adjuvant radiation substantially reduces local recurrence, distant recurrence, and mortality for patients with one to three involved nodes.

    Approximately 13% of women diagnosed with endometrial cancer present with advanced stage disease (International Federation of Gynecology and Obstetrics (FIGO) stage III/IV). The standard treatment of advanced endometrial cancer consists of cytoreductive surgery followed by radiation therapy, or chemotherapy, or both. There is currently little agreement about which adjuvant treatment is the safest and most effective. To evaluate the effectiveness and safety of adjuvant chemotherapy compared with radiotherapy or chemoradiation, and to determine which chemotherapy agents are most effective in women presenting with advanced endometrial cancer (FIGO stage III/IV). We searched the Cochrane Gynaecological Cancer Collaborative Review Group's Trial Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 10 2013), MEDLINE and EMBASE up to November 2013. Also we searched electronic clinical trial registries for ongoing trials. Randomised controlled trials (RCTs) of adjuvant chemotherapy compared with radiotherapy or chemoradiation in women with FIGO stage III and IV endometrial cancer. Two review authors selected trials, extracted data, and assessed trials for risk of bias. Where necessary, we contacted trial investigators for relevant, unpublished data. We pooled data using the random-effects model in Review Manager (RevMan) software. We included four multicentre RCTs involving 1269 women with primary FIGO stage III/IV endometrial cancer. We considered the trials to be at low to moderate risk of bias. All participants received primary cytoreductive surgery. Two trials, evaluating 620 women (83% stage III, 17% stage IV), compared adjuvant chemotherapy with adjuvant radiotherapy; one trial evaluating 552 women (88% stage III, 12% stage IV) compared two chemotherapy regimens (cisplatin/doxorubicin/paclitaxel (CDP) versus cisplatin/doxorubicin (CD) treatment) in women who had all undergone adjuvant radiotherapy; and one trial contributed no data

    Metastatic gastric cancer remains a non-curative disease.Palliative chemotherapy has been demonstrated to prolong survival without quality of life compromise. Many single-agents and combinations have been confirmed to be active in the treatment of metastatic disease. Objective response rates ranged from 10-30% for single-agent therapy and 30-60% for polychemotherapy. Results of phase Ⅱ and Ⅲ studies are reviewed in this paper as well as the potential efficacy of new drugs. For patients with localized disease, the role of adjuvant and neoadjuvant chemotherapy and radiation therapy is discussed.Most studies on adjuvant chemotherapy failed to demonstrate a survival advantage, and therefore, it is not considered as standard treatment in most centres. Adjuvant immunochemotherapy has been developed fundamentally in Korea and Japan. A meta-analysis of phase Ⅲ trials with OK-432 suggested that immunochemotherapy may improve survival of patients with curatively resected gastric cancer. Based on the results of US Intergroup 0116study, postoperative chemoradiation has been Accepted as standard care in patients with resected gastric cancer in North America. However, the results are somewhat confounded by the fact that patients underwent less than a recommended D1 lymph node dissection and the pattern of recurrence suggested a positive effect derived from local radiotherapy without any effect on micrometastatic disease.Neoadjuvant chemotherapy or chemoradiation therapy remains experimental, but several phase Ⅱstudies are showing promising results. Phase Ⅲ trials are needed.

    Oncoplastic reconstructive surgery is performed in select patients with breast cancer to allow conservation treatment when the lumpectomy would be expected to have a poor cosmetic outcome. These techniques not only rearrange the breast tissue but may also shift the position of the tumor bed. The oncoplastic incision may have no relationship to the tumor bed. Although use of whole-breast radiation therapy (RT) is straightforward, difficulties in localization of the tumor bed for the local RT boost have not been investigated. A retrospective review was performed of 25 patients with 26 cancers who received RT after breast conservation surgery with oncoplastic reconstruction. Among 11 patients with a minimum of 4 surgical clips placed at tumor resection, 8 (73%) had the final tumor bed extend beyond the original breast quadrant or be completely relocated into a different region. In 3 (27%) cases, the clinical treatment volume was 2 to 3 separated regions within the breast. For breast cancer patients who have had oncoplastic surgery, the tumor bed is frequently more extensive and possibly relocated compared with original presentation. Placement of surgical clips after tumor resection and before oncoplastic reconstruction may be the most accurate method to localize the RT local boost field.

    Purpose: The purpose of this study was to evaluate the role of involved-lesion radiation therapy (ILRT) after rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) chemotherapy in limited stage diffuse large B-cell lymphoma (DLBCL) by comparing outcomes of R-CHOP therapy alone with R-CHOP followed by ILRT. Methods and Materials: We identified 198 patients treated with R-CHOP (median, 6 cycles) for pathologically confirmed DLBCL of limited stage from July 2004 to December 2012. Clinical characteristics of these patients were 33% with stage I and 66.7% with stage II; 79.8% were in the low or low-intermediate risk group; 13.6% had B symptoms; 29.8% had bulky tumors (≥7 cm); and 75.3% underwent ≥6 cycles of R-CHOP therapy. RT was given to 43 patients (21.7%) using ILRT technique, which included the prechemotherapy tumor volume with a median margin of 2 cm (median RT dose: 36 Gy). Results: After a median follow-up of 40 months, 3-year progression-free survival (PFS) and overall survival (OS) were 85.8% and 88.9%, respectively. Multivariate analysis showed ≥6 cycles of R-CHOP (PFS, P=.004; OS, P=.004) and ILRT (PFS, P=.021; OS, P=.014) were favorable prognosticators of PFS and OS. A bulky tumor (P=.027) and response to R-CHOP (P=.012) were also found to be independent factors of OS. In subgroup analysis, the effect of ILRT was prominent in patients with a bulky tumor (PFS, P=.014; OS, P=.030) or an elevated level of serum lactate dehydrogenase (LDH; PFS, P=.004; OS, P=.012). Conclusions: Our results suggest that ILRT after R-CHOP therapy improves PFS and OS in patients with limited stage DLBCL, especially in those with bulky disease or an elevated serum LDH level.

    Purpose: To report quality of life (QOL) results for patients receiving chemoradiation therapy for pancreatic cancer. Methods and Materials: Eligible patients (n=41 locally advanced, n=22 postsurgery) entered the B9E-AY-S168 study and received 1 cycle of induction gemcitabine (1000 mg/m{sup 2} weekly Multiplication-Sign 3 with 1-week break) followed by 3-dimensional conformal radiation therapy (RT) (54 Gy locally advanced and 45 Gy postsurgery) and concomitant continuous-infusion 5-fluorouracil (5FU) (200 mg/m{sup 2}/d throughout RT). After 4 weeks, patients received an additional 3 cycles of consolidation gemcitabine chemotherapy. Patients completed the European Organization for Research and Treatment of Cancer QLQ-C30 and QLQ-PAN26 questionnaires at baseline, before RT/5FU, at end of RT/5FU, before consolidation gemcitabine, and at treatment completion. Results: The patterns of change in global QOL scores differed between groups. In the locally advanced group global QOL scores were +13, +8, +3, and +1 compared with baseline before RT/5FU (P=.008), at end of RT/5FU, before consolidation gemcitabine, and at treatment completion, respectively. In the postsurgery group, global QOL scores were -3, +4, +15, and +17 compared with baseline at the same time points, with a significant improvement in global QOL before consolidation gemcitabine (P=.03). No significant declines in global QOL were reported by either cohort. Conclusions: This study demonstrates that global QOL and associated function and symptom profiles for pancreatic chemoradiation therapy differ between locally advanced and postsurgery patients, likely owing to differences in underlying disease status. For both groups, the treatment protocol was well tolerated and did not have a negative impact on patients' global QOL.

    Purpose: The role of consolidative radiation therapy (RT) for stage III and IV diffuse large B-cell lymphoma (DLBCL) in the era of rituximab is not well defined. There is evidence that some patients with bulky disease may benefit, but patient selection criteria are not well established. We sought to identify a subset of patients who experienced a high local failure rate after receiving rituximab-based chemotherapy alone and hence may benefit from the addition of consolidative RT. Methods and Materials: Two hundred eleven patients with stage III and IV DLBCL treated between August 1999 and January 2012 were reviewed. Of these, 89 had a complete response to systemic therapy including rituximab and received no initial RT. Kaplan-Meier analysis and Cox proportional hazards regression were performed, with local recurrence (LR) as the primary outcome. Results: The median follow-up time was 43.9 months. Fifty percent of patients experienced LR at 5 years. In multivariate analysis, tumor ≥5 cm and stage III disease were associated with increased risk of LR. The 5-year LR-free survival was 47.4% for patients with ≥5-cm lesions versus 74.7% for patients with <5-cm lesions (P=.01). In patients with <5-cm tumors, the maximum standardized uptake value (SUVmax) was ≥15 in all patients with LR. The 5-year LR-free survival was 100% in SUV<15 versus 68.8% in SUV≥15 (P=.10). Conclusions: Advanced-stage DLBCL patients with stage III disease or with disease ≥5 cm appear to be at an increased risk for LR. Patients with <5-cm disease and SUVmax ≥15 may be at higher risk for LR. These patients may benefit from consolidative RT after chemoimmunotherapy.

    Full Text Available In this paper, we reviewed the long-term survival outcomes, safety, and quality-of-life of androgen-deprivation therapy (ADT alone versus combined with radiation therapy (RT or chemotherapy for locally advanced and metastatic prostate cancer (PCa. A literature search was performed using OvidSP. Randomized controlled trials (RCTs that met the following criteria were included: including locally advanced or metastatic PCa, comparing ADT alone versus combined with any treatment method and reporting quantitative data of disease control or survival outcomes. Finally, eight RCTs met the inclusion criteria. Among these, three compared ADT versus ADT plus RT (n = 2344 and one compared ADT versus ADT plus docetaxel-estramustine (n = 413 in locally advanced PCa; two compared ADT versus ADT plus docetaxel (n = 1175 and two compared ADT versus ADT plus estramustine (n = 114 in metastatic PCa. For locally advanced PCa, the addition of RT to long-term ADT can improve the outcomes of survival and tumor control with fully acceptable adverse effects. Specially, the pooled odds ratio (OR of overall survival (OS was 1.43 (95% confidence interval 1.20-1.71 when compared ADT plus RT with ADT alone (P < 0.0001. For metastatic hormonally sensitive PCa, the concurrent use of docetaxel plus ADT was effective and safe (pooled OR of OS: 1.29 [1.01-1.65]: P = 0.04. In all, long-term ADT plus RT and long-term ADT plus docetaxel should be considered as proper treatment option in locally advanced and metastatic hormonally sensitive PCa, respectively. The major limitation for the paper was that only eight RCTs were available.

    Full Text Available Abstract Background To prospectively evaluate the efficacy and safety of selective internal radiation (SIR spheres in patients with inoperable liver metastases from colorectal cancer who have failed 5FU based chemotherapy. Methods Patients were prospectively enrolled at three Australian centres. All patients had previously received 5-FU based chemotherapy for metastatic colorectal cancer. Patients were ECOG 0–2 and had liver dominant or liver only disease. Concurrent 5-FU was given at investigator discretion. Results Thirty patients were treated between January 2002 and March 2004. As of July 2004 the median follow-up is 18.3 months. Median patient age was 61.7 years (range 36 – 77. Twenty-nine patients are evaluable for toxicity and response. There were 10 partial responses (33%, with the median duration of response being 8.3 months (range 2–18 and median time to progression of 5.3 mths. Response rates were lower (21% and progression free survival shorter (3.9 mths in patients that had received all standard chemotherapy options (n = 14. No responses were seen in patients with a poor performance status (n = 3 or extrahepatic disease (n = 6. Overall treatment related toxicity was acceptable, however significant late toxicity included 4 cases of gastric ulceration. Conclusion In patients with metastatic colorectal cancer that have previously received treatment with 5-FU based chemotherapy, treatment with SIR-spheres has demonstrated encouraging activity. Further studies are required to better define the subsets of patients most likely to respond.

    Purpose: Radiation Therapy Oncology Group 0417 was a phase II study that explored the safety and efficacy of the addition of bevacizumab to chemoradiation therapy. The safety results have been previously reported. Herein we report the secondary efficacy endpoints of overall survival (OS), locoregional failure (LRF), para-aortic nodal failure (PAF), distant failure (DF), and disease-free survival (DFS). Methods and Materials: Eligible patients with bulky Stage IB-IIIB disease were treated with once-weekly cisplatin (40 mg/m{sup 2}) chemotherapy and standard pelvic radiation therapy and brachytherapy. Bevacizumab was administered at 10 mg/kg intravenously every 2 weeks for 3 cycles during chemoradiation. For OS, failure was defined as death of any cause and was measured from study entry to date of death. LRF was defined as any failure in the pelvis. PAF was defined as any para-aortic nodal failure. DF was analyzed both including and excluding PAF. DFS was measured from study entry to date of first LRF. DF was measured with or without PAF or death. OS and DFS were estimated by the Kaplan-Meier method, and LRF and DF rates were estimated by the cumulative incidence method. Results: 49 eligible patients from 28 institutions were enrolled between 2006 and 2009. The median follow-up time was 3.8 years (range, 0.8-6.0 years). The surviving patients had a median follow-up time of 3.9 years (range, 2.1-6.0 years). Most patients had tumors of International Federation of Gynecology and Obstetrics Stage IIB (63%), and 80% were squamous. The 3-year OS, DFS, and LRF were 81.3% (95% confidence interval [CI], 67.2%-89.8%), 68.7% (95% CI, 53.5%-79.8%), and 23.2% (95% CI, 11%-35.4%), respectively. The PAF, DF without PAF, and DF with PAF at 3 years were 8.4% (95% CI, 0.4%-16.3%), 14.7% (95% CI, 4.5%-24.9%), and 23.1% (95% CI 11.0%-35.2%), respectively. Conclusion: In this study, bevacizumab in combination with standard pelvic chemoradiation therapy for locally advanced cervical

    Purpose: In the European HIT-SIOP PNET4 randomized controlled trial, children with standard risk medulloblastoma were allocated to hyperfractionated radiation therapy (HFRT arm, including a partially focused boost) or standard radiation therapy (STRT arm), followed, in both arms, by maintenance chemotherapy. Event-free survival was similar in both arms. Previous work showed that the HFRT arm was associated with worse growth and better questionnaire-based executive function, especially in children <8 years of age at diagnosis. Therefore, the aim of this study was to compare performance-based cognitive outcomes between treatment arms. Methods and Materials: Neuropsychological data were collected prospectively in 137 patients. Using the Wechsler Intelligence Scales, Kaufman Assessment Battery for Children, and Raven's Progressive Matrices, we estimated full-scale intelligence quotient (FSIQ) and, when available, verbal IQ (VIQ), performance IQ (PIQ), working memory index (WMI), and processing speed index (PSI). Results: Among the 137 participants (HFRT arm n=71, STRT arm n=66, 63.5% males), mean (±SD) ages at diagnosis and assessment respectively were 9.3 (±3.2) years of age (40.8% < 8 years of age at diagnosis) and 14.6 (±4.3) years of age. Mean (±SD) FSIQ was 88 (±19), and mean intergroup difference was 3.88 (95% confidence interval: −2.66 to 10.42, P=.24). No significant differences were found in children >8 years of age at diagnosis. In children <8 years of age at diagnosis, a marginally significant trend toward higher VIQ was found in those treated in the HFRT arm; a similar trend was found for PSI but not for PIQ, WMI, or FSIQ (mean intergroup differences were: 12.02 for VIQ [95% CI: 2.37-21.67; P=.02]; 3.77 for PIQ [95% CI: −5.19 to 12.74; P>.10]; 5.20 for WMI [95% CI: −2.07 to 12.47; P>.10]; 10.90 for PSI [95% CI: −1.54 to 23.36; P=.08]; and 5.28 for FSIQ [95% CI: −4.23 to 14.79; P>.10]). Conclusions: HFRT was associated with

    To examine the effect of suboptimal chemotherapy in patients undergoing preoperative chemoradiotherapy for the treatment of rectal cancer. The medical records of 43 patients who received preoperative concurrent chemoradiotherapy, followed by radical surgery for the treatment of pathologically proven adenocarcinoma of the rectum from April 2003 to April 2006 were retrospectively reviewed. The delivered radiation dose ranged from 41.4 to 50.4 Gy. The standard group consisted of patients receiving two cycles of a 5-FU bolus injection for three days on the first and fifth week of radiotherapy or twice daily with capecitabine. The standard group included six patients for each regimen. The non-standard group consisted of patients receiving one cycle of 5-FU bolus injection for three days on the first week of radiotherapy. The non-standard group included 31 patients. Radical surgery was performed at a median of 58 days after the end of radiotherapy. A low anterior resection was performed in 36 patients, whereas an abdominoperineal resection was performed in 7 patients. No significant difference was observed between the groups with respect to pathologic responses ranging from grades 3 to 5 (83.3% vs. 67.7%, p=0.456), downstaging (75.0% vs. 67.7%, p=0.727), and a radial resection margin greater than 2 mm (66.7% vs. 83.9%, p=0.237). The sphincter-saving surgery rate in low-lying rectal cancers was lower in the non-standard group (100% vs. 75%, p=0.068). There was no grade 3 or higher toxicity observed in all patients. Considering that the sphincter-saving surgery rate in low-lying rectal cancer was marginally lower for patients treated with non-standard, suboptimal chemotherapy, and that toxicity higher than grade 2 was not observed in the both groups, suboptimal chemotherapy should be avoided in this setting.

    Full Text Available Introduction/Aim. Lung cancer is a leading cause of mortality among patients with carcinomas. The aim of this study was to point out risk factors for brain metastases (BM appearance in patients with IIIA (N2 stage of nonsmall cell lung cancer (NSCLC treated with three-modal therapy. Methods. We analyzed data obtained from 107 patients with IIIA (N2 stage of NSCLC treated surgically with neoadjuvant therapy. The frequency of brain metastases was examined regarding age, sex, histological type and the size of tumor, nodal status, the sequence of radiotherapy and chemotherapy application and the type of chemotherapy. Results. Two and 3-year incidence rates of BM were 35% and 46%, respectively. Forty-six percent of the patients recurred in the brain as their first failure in the period of three years. Histologically, the patients with nonsquamous cell lung carcinoma had significantly higher frequency of metastases in the brain compared with the group of squamous cell lung carcinoma (46% : 30%; p = 0.021. Examining treatment-related parameters, treatment with taxane-platinum containing regimens was associated with a lower risk of brain metastases, than platinum-etoposide chemotherapy regimens (31% : 52%; p = 0.011. Preoperative radiotherapy, with or without postoperative treatment, showed lower rate of metastases in the brain compared with postoperative radiotherapy treatment only (33% : 48%; p = 0.035. Conclusion. Brain metastases are often site of recurrence in patients with NSCLC (IIIA-N2. Autonomous risk factors for brain metastases in this group of patients are non-squamous NSCLC, N1-N2 nodal status, postoperative radiotherapy without preoperative radiotherapy.

    Purpose: The purpose of this study was to investigate the role of postmastectomy radiation therapy (PMRT) after neoadjuvant chemotherapy (NAC) in clinical stage II-III breast cancer patients with pN0. Methods and Materials: We retrospectively identified 417 clinical stage II-III breast cancer patients who achieved an ypN0 at surgery after receiving NAC between 1998 and 2009. Of these, 151 patients underwent mastectomy after NAC. The effect of PMRT on disease-free survival (DFS), locoregional recurrence-free survival (LRRFS), and overall survival (OS) was evaluated by multivariate analysis including known prognostic factors using the Kaplan-Meier method and compared using the log–rank test and Cox proportional regression analysis. Results: Of the 151 patients who underwent mastectomy, 105 (69.5%) received PMRT and 46 patients (30.5%) did not. At a median follow-up of 59 months, 5 patients (3.3%) developed LRR (8 sites of recurrence) and 14 patients (9.3%) developed distant metastasis. The 5-year DFS, LRRFS, and OS rates were 91.2, 98.1, and 93.3% with PMRT and 83.0%, 92.3%, and 89.9% without PMRT, respectively (all P values not significant). By univariate analysis, only age (≤40 vs >40 years) was significantly associated with decreased DFS (P=.027). By multivariate analysis, age (≤40 vs >40 years) and pathologic T stage (0-is vs 1 vs 2-4) were significant prognostic factors affecting DFS (hazard ratio [HR] 0.353, 95% confidence interval [CI] 0.135-0.928, P=.035; HR 2.223, 95% CI 1.074-4.604, P=.031, respectively). PMRT showed no correlation with a difference in DFS, LRRFS, or OS by multivariate analysis. Conclusions: PMRT might not be necessary for pN0 patients after NAC, regardless of clinical stage. Prospective randomized clinical trial data are needed to assess whether PMRT can be safely omitted in pN0 patients after NAC and mastectomy for clinical stage II-III breast cancer.

    Ovarian cancer (OC) remains relatively rare, although it is among the top 4 causes of cancer death for women younger than 50. The aggressive nature of the disease and its often late diagnosis with peritoneal involvement have an impact on prognosis. The current scientific literature presents ambiguous or uncertain indications for management of peritoneal carcinosis (PC) from OC, both owing to the lack of sufficient scientific data and their heterogeneity or lack of consistency. Therefore, the Italian Society of Surgical Oncology (SICO), the Italian Society of Obstetrics and Gynaecology, the Italian Association of Hospital Obstetricians and Gynaecologists, and the Italian Association of Medical Oncology conducted a multidisciplinary consensus conference (CC) on management of advanced OC presenting with PC during the SICO annual meeting in Naples, Italy, on September 10-11, 2015. An expert committee developed questions on diagnosis and staging work-up, indications, and procedural aspects for peritonectomy, systemic chemotherapy, and hyperthermic intraperitoneal chemotherapy for PC from OC. These questions were provided to 6 invited speakers who answered with an evidence-based report. Each report was submitted to a jury panel, representative of Italian experts in the fields of surgical oncology, gynecology, and medical oncology. The jury panel revised the reports before and after the open discussion during the CC. This article is the final document containing the clinical evidence reports and statements, revised and approved by all the authors before submission.

    Full Text Available Objective: The objective of this study was to compare robotic-prostatectomy plus adjuvant radiation therapy (RPRAT versus primary RT for high-risk prostate cancer (HRPCa. Materials and Methods: A retrospective chart review was performed for the HRPCa patients treated in our institution between 2000 and 2010. One hundred and twenty-three patients with high-risk disease were identified. The Chi-square test and Fisher′s exact test were used to compare local control and distant failure rates between the two treatment modalities. For prostate-specific antigen comparisons between groups, Wilcoxon rank-sum test was used. Results: The median follow-up was 49 months (range: 3-138 months. Local control, biochemical recurrence rate, distant metastasis, toxicity, and disease-free survival were similar in the two groups. Conclusions: Primary RT is an excellent treatment option in patients with HRPCa, is equally effective and less expensive treatment compared with RPRAT. A prospective randomized study is required to guide treatment for patients with HRPCa.

    Purpose: The purpose of this study was to reveal the biological mechanisms underlying stereotactic body radiation therapy (SBRT) and stereotactic radiation surgery (SRS). Methods and Materials: FSaII fibrosarcomas grown subcutaneously in the hind limbs of C3H mice were irradiated with 10 to 30 Gy of X rays in a single fraction, and the clonogenic cell survival was determined with in vivo–in vitro excision assay immediately or 2 to 5 days after irradiation. The effects of radiation on the intratumor microenvironment were studied using immunohistochemical methods. Results: After cells were irradiated with 15 or 20 Gy, cell survival in FSaII tumors declined for 2 to 3 days and began to recover thereafter in some but not all tumors. After irradiation with 30 Gy, cell survival declined continuously for 5 days. Cell survival in some tumors 5 days after 20 to 30 Gy irradiation was 2 to 3 logs less than that immediately after irradiation. Irradiation with 20 Gy markedly reduced blood perfusion, upregulated HIF-1α, and increased carbonic anhydrase-9 expression, indicating that irradiation increased tumor hypoxia. In addition, expression of VEGF also increased in the tumor tissue after 20 Gy irradiation, probably due to the increase in HIF-1α activity. Conclusions: Irradiation of FSaII tumors with 15 to 30 Gy in a single dose caused dose-dependent secondary cell death, most likely by causing vascular damage accompanied by deterioration of intratumor microenvironment. Such indirect tumor cell death may play a crucial role in the control of human tumors with SBRT and SRS.

    Purpose: To propose, verify, and implement a simple and efficient methodology for the improvement of total geometric accuracy in multiple brain metastases gamma knife (GK) radiation surgery. Methods and Materials: The proposed methodology exploits the directional dependence of magnetic resonance imaging (MRI)-related spatial distortions stemming from background field inhomogeneities, also known as sequence-dependent distortions, with respect to the read-gradient polarity during MRI acquisition. First, an extra MRI pulse sequence is acquired with the same imaging parameters as those used for routine patient imaging, aside from a reversal in the read-gradient polarity. Then, “average” image data are compounded from data acquired from the 2 MRI sequences and are used for treatment planning purposes. The method was applied and verified in a polymer gel phantom irradiated with multiple shots in an extended region of the GK stereotactic space. Its clinical impact in dose delivery accuracy was assessed in 15 patients with a total of 96 relatively small (<2 cm) metastases treated with GK radiation surgery. Results: Phantom study results showed that use of average MR images eliminates the effect of sequence-dependent distortions, leading to a total spatial uncertainty of less than 0.3 mm, attributed mainly to gradient nonlinearities. In brain metastases patients, non-eliminated sequence-dependent distortions lead to target localization uncertainties of up to 1.3 mm (mean: 0.51 ± 0.37 mm) with respect to the corresponding target locations in the “average” MRI series. Due to these uncertainties, a considerable underdosage (5%-32% of the prescription dose) was found in 33% of the studied targets. Conclusions: The proposed methodology is simple and straightforward in its implementation. Regarding multiple brain metastases applications, the suggested approach may substantially improve total GK dose delivery accuracy in smaller, outlying targets.

    The reversal of anorexia and weight loss especially in patients with advanced cancer suffering from radiation treatment (RT) -related complications and debilitated further during RT would be a welcome relief. The purpose of this study is to evaluate the feasibility of supportive treatment with megestrol acetate (MA) in the weight-losing cancer patients increasingly experiencing anorexia, smell, taste, and weight loss due to the additive adverse effects of RT plus or minus chemotherapy and how MA changes the additive role of the severity of RT reactions on such patients. >From June 1997 to October 1998, 100 eligible patients were enrolled on a randomized, placebo-controlled clinical trial. Of the 100 patients, 46 received MA during RT and 4 after the end of the RT, and 50 received placebo for 3 months. Subjective parameters were assessed by a brief questionnaire form based on scoring from 1 to 5, according to the degree of the loss or change for each parameter of malnutrition, appetite, taste and smell developed by the researchers. At the end of the study a statistically significant weight gain was achieved in the patient group receiving MA compared to the placebo group (+ 3 to + 5 kg versus -3.7 to -5.9 kg, p=0.000). Significant improvements were seen in performance status (p=0.000), appetite (p=0.000), malnutrition (p=0.000), loss of taste (p=0.000) and smell qualities (p=0.02) in the MA group compared to the placebo group. In the MA group there was no statistically significant difference related to the weight changes according to the grade of either the acute or late RT effects (p=0.65 and 0.07, respectively). Whereas, in the placebo group a statistically significant additive effect of the acute and late RT effects was detected on weight loss (p=0.008 and 0.007, respectively). It was observed no side-effects of MA in a 3-month time follow-up. The use of MA 480 mg/day during RT was effective in reversing anorexia and weight loss in spite of the acute RT effects

    To describe voice and speech quality changes and their predictors in patients with locally advanced oropharyngeal cancer treated on prospective clinical studies of organ-preserving chemotherapy-intensity modulated radiation therapy (chemo-IMRT). Ninety-one patients with stage III/IV oropharyngeal cancer were treated on 2 consecutive prospective studies of definitive chemoradiation using whole-field IMRT from 2003 to 2011. Patient-reported voice and speech quality were longitudinally assessed from before treatment through 24 months using the Communication Domain of the Head and Neck Quality of Life (HNQOL-C) instrument and the Speech question of the University of Washington Quality of Life (UWQOL-S) instrument, respectively. Factors associated with patient-reported voice quality worsening from baseline and speech impairment were assessed. Voice quality decreased maximally at 1 month, with 68% and 41% of patients reporting worse HNQOL-C and UWQOL-S scores compared with before treatment, and improved thereafter, recovering to baseline by 12-18 months on average. In contrast, observer-rated larynx toxicity was rare (7% at 3 months; 5% at 6 months). Among patients with mean glottic larynx (GL) dose ≤20 Gy, >20-30 Gy, >30-40 Gy, >40-50 Gy, and >50 Gy, 10%, 32%, 25%, 30%, and 63%, respectively, reported worse voice quality at 12 months compared with before treatment (P=.011). Results for speech impairment were similar. Glottic larynx dose, N stage, neck dissection, oral cavity dose, and time since chemo-IMRT were univariately associated with either voice worsening or speech impairment. On multivariate analysis, mean GL dose remained independently predictive for both voice quality worsening (8.1%/Gy) and speech impairment (4.3%/Gy). Voice quality worsening and speech impairment after chemo-IMRT for locally advanced oropharyngeal cancer were frequently reported by patients, underrecognized by clinicians, and independently associated with GL dose. These findings support

    Purpose: To determine the ability of pharmacokinetic parameters derived from dynamic contrast-enhanced MRI (DCE- MRI) acquired before and during concurrent chemotherapy and radiation therapy to predict clinical response in patients with head and neck cancer. Methods: Eleven patients underwent a DCE-MRI scan at three time points: 1–2 weeks before treatment, 4–5 weeks after treatment initiation, and 3–4 months after treatment completion. Post-processing of MRI data included correction to reduce motion artifacts. The arterial input function was obtained by measuring the dynamic tracer concentration in the jugular veins. The volume transfer constant (Ktrans), extracellular extravascular volume fraction (ve), rate constant (Kep; Kep = Ktrans/ve), and plasma volume fraction (vp) were computed for primary tumors and cervical nodal masses. Patients were categorized into two groups based on response to therapy at 3–4 months: responders (no evidence of disease) and partial responders (regression of disease). Responses of the primary tumor and nodes were evaluated separately. A linear classifier and receiver operating characteristic curve analyses were used to determine the best model for discrimination of responders from partial responders. Results: When the above pharmacokinetic parameters of the primary tumor measured before and during treatment were incorporated into the linear classifier, a discriminative accuracy of 88.9%, with sensitivity =100% and specificity = 66.7%, was observed between responders (n=6) and partial responders (n=3) for the primary tumor with the corresponding accuracy = 44.4%, sensitivity = 66.7%, and specificity of 0% for nodal masses. When only pre-treatment parameters were used, the accuracy decreased to 66.7%, with sensitivity = 66.7% and specificity = 66.7% for the primary tumor and decreased to 33.3%, sensitivity of 50%, and specificity of 0% for nodal masses. Conclusion: Higher accuracy, sensitivity, and specificity were obtained

    AIM: To study the outcome of patients undergoing surgical resection of the bowel for sustained radiation-induced damage intractable to conservative management.METHODS: During a 7-year period we operated on 17 cases (5 male, 12 female) admitted to our surgical department with intestinal radiation injury (IRI). They were originally treated for a pelvic malignancy by surgical resection followed by postoperative radiotherapy. During follow-up, they developed radiation enteritis requiring surgical treatment due to failure of conservative management.RESULTS: IRI was located in the terminal ileum in 12 patients, in the rectum in 2 patients, in the descending colon in 2 patients, and in the cecum in one patient. All patients had resection of the affected region(s). There were no postoperative deaths, while 3 cases presented with postoperative complications (17.7%). All patients remained free of symptoms without evidence of recurrence of IRI for a median follow-up period of 42 mo (range, 6-96 mo).CONCLUSION: We report a favorable outcome without IRI recurrence of 17 patients treated by resection of the diseased bowel segment.

    Purpose: To evaluate cosmetic outcome and its association with breast wound seroma after breast-conserving surgery (BCS) with targeted intraoperative radiation therapy (tIORT) boost for early breast cancer. Methods and Materials: An analysis of a single-arm prospective study of 55 patients with early breast cancer treated with BCS and tIORT boost followed by conventional whole breast radiation therapy (WBRT) between August 2003 and January 2006 was performed. A seroma was defined as a fluid collection at the primary tumor resection site identified clinically or radiologically. Cosmetic assessments using the European Organization for Research and Treatment of Cancer rating system were performed at baseline before BCS and 30 months after WBRT was completed. Results: Twenty-eight patients (51%) developed a seroma, with 18 patients (33%) requiring at least 1 aspiration. Tumor location was significantly associated with seroma formation (P=.001). Ten of 11 patients with an upper inner quadrant tumor developed a seroma. Excellent or good overall cosmetic outcome at 30 months was observed in 34 patients (62%, 95% confidence interval 53%-80%). Seroma formation was not associated with the overall cosmetic result (P=.54). Conclusion: BCS with tIORT boost followed by WBRT was associated with an acceptable cosmetic outcome. Seroma formation was not significantly associated with an adverse cosmetic outcome.

    Our purpose was to examine the incidence and impact on survival of other primary malignancies (OPM) outside of the breast in breast cancer patients and to identify risk factors associated with OPM. Patients with stage 0-III breast cancer treated with breast conserving therapy at our center from 1979 to 2007 were included. Risk factors were compared between patients with/without OPM. Logistic regression was used to identify factors that were associated with OPM. Standardized incidence ratios (SIRs) were calculated. Among 4,198 patients in this study, 276 (6.6 %) developed an OPM after breast cancer treatment. Patients with OPM were older and had a higher proportion of stage 0/I disease and contralateral breast cancer compared with those without OPM. In a multivariate analysis, older patients, those with contralateral breast cancer, and those who did not receive chemotherapy or hormone therapy were more likely to develop OPM after breast cancer. Patients without OPM had better overall survival. The SIR for all OPM sites combined after a first primary breast cancer was 2.91 (95 % confidence interval: 2.57-3.24). Significantly elevated risks were seen for numerous cancer sites, with SIRs ranging from 1.84 for lung cancer to 5.69 for ovarian cancer. Our study shows that breast cancer patients have an increased risk of developing OPM over the general population. The use of systemic therapy was not associated with increased risk of OPM. In addition to screening for a contralateral breast cancer and recurrences, breast cancer survivors should undergo screening for other malignancies.

    Combined modality therapy, consisting of radiation, chemotherapy and surgery are used to treat primary tumours aiming to preserve function and increase tumour control. In the present prospective trial 112 patients underwent combined preoperative radio-chemotherapy, 35 patients were treated with combined radio-chemotherapy as only treatment. At a median follow-up of 26 months eight patients (2.8%) have developed an osteo-radionectrosis, which is comparable with data from the literature. When known risk factors are avoided the incidence of osteo-radionecrosis is not increased following combined therapy. The most important factors for development of osteo-radionecrosis following radio-chemotherapy are large tumours and tumor infiltration in the mandible. (orig.).

    2016-01-01

    Salvage primary tumor resection is sometimes considered for isolated local failures after definitive chemoradiation, urgent matters, such as hemoptysis (palliative intent), and in cases judged to be contraindicated for chemotherapy or definite radiation due to severe comorbidities, despite an initial clinical diagnosis of stage III or IV disease. However, salvage surgery is generally considered to be technically more difficult, with a potentially higher morbidity. This review discusses the current topics on salvage thoracic surgery such as the definition of salvage surgery and its outcome, and future perspectives. PMID:26948299

    Full Text Available Soft tissue sarcomas (STSs are an uncommon and diverse group of more than 50 mesenchymal malignancies. Each of these histologic subtypes represents a unique disease with distinct biologic behavior and varying sensitivity to chemotherapy. The judicious use of adjuvant/neoadjuvant chemotherapy along with surgery and radiation in the treatment of localized STS has a role in improving patient outcomes by decreasing local and distant recurrences. There is evidence that the use of adjuvant chemotherapy to a mixed cohort of chemo sensitive and insensitive sarcoma subtypes results in limited benefit. Therefore, it is of paramount importance to identify the subpopulation with high metastatic potential and to identify effective histology-specific treatment options to these patients. Present perspective, will focus on the rationale for adjuvant chemotherapy in sarcoma, with emphasis on the histology driven chemotherapy. It will outline key therapeutic opportunities and hurdles in adjuvant medical treatment of sarcoma, focusing on specific subtypes that are on the verge of new breakthroughs, as well as those in which promise has not lived up to expectations.

    Purpose: To assess the value of mid-therapy positron emission tomography (PET) findings for predicting survival and disease progression in patients with diffuse large B-cell lymphoma, considering type of therapy (chemotherapy with or without radiation therapy). Methods and Materials: We retrospectively evaluated 294 patients with histologically confirmed diffuse large B-cell lymphoma with respect to age, sex, disease stage, International Prognostic Index score, mid-therapy PET findings (positive or negative), and disease status after therapy and at last follow-up. Overall survival (OS) and progression-free survival (PFS) were compared according to mid-therapy PET findings. Results: Of the 294 patients, 163 (55%) were male, 144 (49%) were age >61 years, 110 (37%) had stage I or II disease, 219 (74%) had International Prognostic Index score ≤2, 216 (73%) received ≥6 cycles of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone, and 88 (30%) received consolidation radiation therapy. Five-year PFS and OS rates were associated with mid-therapy PET status: PFS was 78% for those with PET-negative (PET−) disease versus 63% for PET-positive (PET+) disease (P=.024), and OS was 82% for PET− versus 62% for PET+ (P<.002). These associations held true for patients who received chemotherapy only (PFS 71% for PET− vs 52% PET+ [P=.012], OS 78% for PET− and 51% for PET+ [P=.0055]) but not for those who received consolidation radiation therapy (PFS 84% PET− vs 81% PET+ [P=.88]; OS 90% PET− vs 81% PET+ [P=.39]). Conclusion: Mid-therapy PET can predict patient outcome, but the use of consolidation radiation therapy may negate the significance of mid-therapy findings.

    The best management for small mucosal esophageal cancer is generally endoscopic mucosal resection. However, for submucosal cancer and extensive mucosal caner, either radical surgery or radiation seems to be an equally efficacious option. Radiation therapy concurrent with chemotherapy is more effective than radiation therapy alone for patients with unresectable esophageal cancer. The key drugs are cisplatin and 5-fluorouracil. However, for patients with poor performance status or for aged patients, radiation therapy alone is still a choice of treatment. Surgery has generally been indicated for patients with resectable esophageal cancer. However, outcomes of concurrent chemoradiation therapy may be comparable with those of surgery. Therefore, a prospective randomized study should be performed to determine the best management for patients with resectable esophageal cancer. The usefulness of intra-cavitary irradiation for esophageal cancer has not been clarified. A prospective randomized trial with a large number of patients is necessary to determine the effectiveness of intra-cavitary irradiation. The best management for patients with loco-regionally recurrent esophageal cancer after surgery has not been determined. Intensive therapy should be considered if the site of recurrence is limited and the time interval from surgery to recurrence is long. Chemotherapy is essential in the management of patients with small cell esophageal cancer. However, the best local therapy has not been determined. (author)

    Purpose: The clinical benefits and risks of dose escalation (DE) for stage III non–small-cell lung cancer (NSCLC) remain uncertain despite the results from Radiation Therapy Oncology Group (RTOG) protocol 0617. There is significant heterogeneity of practice, with many clinicians prescribing intermediate dose levels between the 0617 study arms of 60 and 74 Gy. This study investigated whether this strategy is associated with any survival benefits/risks by analyzing a large multi-institutional database. Methods and Materials: An individual patient database of stage III NSCLC patients treated with radical intent concurrent chemoradiation therapy was created (13 institutions, n=1274 patients). Patients were divided into 2 groups based on tumor Biological Effective Dose at 10 Gy (BED 10): those receiving standard dose (SD; n=552), consisting of 72Gy ≤ BED 10 ≤ 76.8 Gy (eg 60-64 Gy/30-32 fractions [fr]), and those receiving intermediate dose (ID; n=497), consisting of 76.8Gy < BED 10 < 100.8 Gy (eg >64 Gy/32 fr and <74 Gy/37 fr), with lower-dose patients (n=225) excluded from consideration. Patients were then matched using propensity scores, leading to 2 matched groups of 196 patients. Outcomes were compared using various statistics including interquartile range (IQR), Kaplan-Meier curves, and adjusted Cox regression analysis. Results: Matched groups were found to be balanced except for N stage (more N3 disease in SD), median treatment year (SD in 2003; ID in 2007), platinum and taxane chemotherapy (SD in 28%; ID in 39%), and median follow-up (SD were 89 months; ID were 40 months). Median dose fractionation was 60 Gy/30 fr in SD (BED 10 IQR: 72.0-75.5 Gy) and 66 Gy/33 fr (BED 10 IQR: 78.6-79.2 Gy) in ID. Survival curves for SD and ID matched cohorts were statistically similar (P=.27); however, a nonstatistically significant trend toward better survival for ID was observed after 15 months (median survival SD: 19.3 months; ID: 21.0

    Objective To evaluate the value of preoperative neoadjuvant chemotherapy ( NAC) and surgery in the treatment of resectable small cell lung cancer ( SCLC). Methods Retrospective study was performed on the clinical and survival data from 82 patients with resectable SCLC who received surgical resection during Jan 2000 to Jan 2005. All patients were divided into two groups : NAC group (preoperative NAC followed by surgery ) and control group (surgery without NAC). Results NAC group had 53 patients and control group had 29 cases. The patients in NAC group were given 1 or 2 cycles of NAC with EP ( etoposide and cisplatin ) regimens , and operations were performed in 2 or 3 weeks after finishing the last chemotherapy. The tumor response to NAC was 81. 1% (43/53). 3 cases had histological complete response . The 1 -, 3 -, 5 -year survival rates were 86. 8 % , 49. 1 % , 28. 3 % in NAC group,and 79. 3% ,31. 0% , 10. 3% in control group respectively.

    Purpose: To determine factors associated with the durability of stereotactic radiation surgery (SRS) for treatment of trigeminal neuralgia (TN). Methods and Materials: Between 1999 and 2008, 446 of 777 patients with TN underwent SRS and had evaluable follow-up in our electronic medical records and phone interview records. The median follow-up was 21.2 months. The Barrow Neurologic Institute (BNI) pain scale was used to determine pre- and post-SRS pain. Dose-volume anatomical measurements, Burchiel pain subtype, pain quality, prior procedures, and medication usage were included in this retrospective cohort to identify factors impacting the time to BNI 4-5 pain relapse by using Cox proportional hazard regression. An internet-based nomogram was constructed based on predictive factors of durable relief pre- and posttreatment at 6-month intervals. Results: Rates of freedom from BNI 4-5 failure at 1, 3, and 5 years were 84.5%, 70.4%, and 46.9%, respectively. Pain relief was BNI 1-3 at 1, 3, and 5 years in 86.1%, 74.3%, and 51.3% of type 1 patients; 79.3%, 46.2%, and 29.3% of type 2 patients; and 62.7%, 50.2%, and 25% of atypical facial pain patients. BNI type 1 pain score was achieved at 1, 3, and 5 years in 62.9%, 43.5%, and 22.0% of patients with type 1 pain and in 47.5%, 25.2%, and 9.2% of type 2 patients, respectively. Only 13% of patients with atypical facial pain achieved BNI 1 response; 42% of patients developed post-Gamma Knife radiation surgery (GKRS) trigeminal dysfunction. Multivariate analysis revealed that post-SRS numbness (hazard ratio [HR], 0.47; P<.0001), type 1 (vs type 2) TN (HR, 0.6; P=.02), and improved post-SRS BNI score at 6 months (HR, 0.009; P<.0001) were predictive of a durable pain response. Conclusions: The durability of SRS for TN depends on the presenting Burchiel pain type, the post-SRS BNI score, and the presence of post-SRS facial numbness. The durability of pain relief can be estimated pre- and posttreatment by using our

    Parathyroid biopsy represents a means for normal and hyperfunctional glands to be distinguished intraoperatively. However, no data exist to guide surgeons regarding how much of a parathyroid gland must be biopsied to satisfy the 20% rule. To quantify the relative proportion of a hyperfunctional parathyroid gland that must be evaluated with the gamma probe to satisfy the 20% rule. A retrospective review of surgical data for 24 consecutive patients (16 women, 18 men; mean [SD] age, 66.6 [10] years; range, 51-83 years) who underwent surgery for primary hyperparathyroidism between May and October, 2015, in a tertieary academic medical center. Extirpated parathyroid glands were sectioned into parallel or pie-shaped biopsies and evaluated ex vivo with a gamma probe to determine what percentage of a hyperfunctional gland must be sampled to meet the Norman 20% rule. The hypothesis was formulated during data collection. In total, 253 ex vivo biopsy specimens were obtained from 33 surgically removed parathyroid glands. Parathyroid biopsies satisfied the 20% rule with an accuracy that depended on the relative proportion of the parent gland represented: half or more (96.6%; 95% CI, 91.7%-100.0%), a quarter to one-half (87.0%; 95% CI, 79.3%-94.7%), less than a quarter (63.6%; 95% CI, 54.5%-72.8%). When less than a quarter of the gland was removed, pie-shaped biopsies were more likely to satisfy the 20% rule compared with parallel biopsies of the same weight (78.4% vs 56.2%; absolute difference, 22.2%; 95% CI, 4.7%-39.7%). Unless half of a parathyroid gland is biopsied during radioguided parathyroidectomy, the 20% rule cannot reliably rule out the presence of a hyperfunctional parathyroid lesion. Pie-shaped biopsies originating from the center of the gland are associated with a lower rate of false-negative results compared with peripheral biopsies of similar size. Pie-shaped biopsies and biopsy of half or more of each nonexcised parathyroid gland for ex vivo counts may increase

    Purpose: The purpose of this study was to evaluate workflow and patient outcomes related to frameless stereotactic radiation surgery (SRS) for brain metastases. Methods and Materials: We reviewed all treatment demographics, clinical outcomes, and workflow timing, including time from magnetic resonance imaging (MRI), computed tomography (CT) simulation, insurance authorization, and consultation to the start of SRS for brain metastases. Results: A total of 82 patients with 151 brain metastases treated with SRS were evaluated. The median times from consultation, insurance authorization, CT simulation, and MRI for treatment planning were 15, 7, 6, and 11 days to SRS. Local freedom from progression (LFFP) was lower in metastases with MRI ≥14 days before treatment (P=.0003, log rank). The 6- and 12-month LFFP rate were 95% and 75% for metastasis with interval of <14 days from MRI to treatment compared to 56% and 34% for metastases with MRI ≥14 days before treatment. On multivariate analysis, LFFP remained significantly lower for lesions with MRI ≥14 days at SRS (P=.002, Cox proportional hazards; hazard ratio: 3.4, 95% confidence interval: 1.6-7.3). Conclusions: Delay from MRI to SRS treatment delivery for brain metastases appears to reduce local control. Future studies should monitor the timing from imaging acquisition to treatment delivery. Our experience suggests that the time from MRI to treatment should be <14 days.

    Conclusion: Chemopotentiating LDFRT combined with paclitaxel and carboplatin is effective in SCCHN and provided an excellent median overall survival of 107.2 months, with median PFS not yet reached in this locally advanced SCCHN cohort. This compares favorably to prior investigations and caused fewer grade 3 and 4 toxicities than more intensive, 3-drug induction regimens. This trial demonstrates the innovative use of LDFRT as a potentiator of chemotherapy.

    Full Text Available Background and objective Chemotherapy is a highly efficient primary treatment for extensive-stage small cell lung cancer (ES-SCLC. However, patients receiving such treatment are prone to develop drug resistance. Local treatment is palliative and thus can alleviate the local symptoms and improve quality of life, but limited evidence is available for prolonging survival. Hence, this study evaluated the role of local treatment in chemotherapy of patients with ES-SCLC. Methods A total of 302 ES-SCLC cases were enrolled in this retrospective study. Prognostic factors were analyzed by Kaplan-Meier and Cox multivariate proportional hazards model. Results Median progression-free survival (PFS and median survival time (MST of the patients were 4.4 and 10.4 months, respectively. 1-, 2-, and 3-year survival rates were 37.8%, 10.2% and 4.4%, correspondingly. The MST of the primary tumor radiotherapy plus chemotherapy group was 14.3 months, whereas that of the chemotherapy group was 8.2 months (P<0.01. The MSTs of multiple-site, single-site, and non-metastasis local treatments were 18.7, 12.3 and 8.9 months, respectively (P<0.01. The MSTs of initiative, passive, and non-metastasis local treatments were 16.0, 10.9 and 9.4 months, correspondingly (P<0.01. The MSTs of patients with prophylactic cranial irradiation (PCI and those without PCI were 19.8 and 9.9 months, respectively (P<0.01. Primary tumor radiotherapy, metastasis local treatment, and PCI were independent prognostic factors for ES-SCLC. Conclusion Primary tumor radiotherapy, metastasis local treatment, and PCI can significantly improve survival in patients with ES-SCLC.

    Purpose: This study compared treatment outcomes of stereotactic body radiation therapy (SBRT) with those of surgery in stage I non-small cell lung cancer (NSCLC). Methods and Materials: Eligible studies of SBRT and surgery were retrieved through extensive searches of the PubMed, Medline, Embase, and Cochrane library databases from 2000 to 2012. Original English publications of stage I NSCLC with adequate sample sizes and adequate SBRT doses were included. A multivariate random effects model was used to perform a meta-analysis to compare survival between treatments while adjusting for differences in patient characteristics. Results: Forty SBRT studies (4850 patients) and 23 surgery studies (7071 patients) published in the same period were eligible. The median age and follow-up duration were 74 years and 28.0 months for SBRT patients and 66 years and 37 months for surgery patients, respectively. The mean unadjusted overall survival rates at 1, 3, and 5 years with SBRT were 83.4%, 56.6%, and 41.2% compared to 92.5%, 77.9%, and 66.1% with lobectomy and 93.2%, 80.7%, and 71.7% with limited lung resections. In SBRT studies, overall survival improved with increasing proportion of operable patients. After we adjusted for proportion of operable patients and age, SBRT and surgery had similar estimated overall and disease-free survival. Conclusions: Patients treated with SBRT differ substantially from patients treated with surgery in age and operability. After adjustment for these differences, OS and DFS do not differ significantly between SBRT and surgery in patients with operable stage I NSCLC. A randomized prospective trial is warranted to compare the efficacy of SBRT and surgery.

    Purpose: Retrospective study of patients treated for high-grade glioma, with or without biodegradable carmustine wafers and according to the Stupp protocol. Methods and Materials: Between May 2007 and June 2008, 65 patients underwent surgery for high-grade glioma, 28 had implantation of Gliadel and 37 patients did not. Patients received radiotherapy with concomitant temozolomide followed by 5 consecutive days of temozolomide every month for 6 months. Results: Overall median follow-up was 17.1 months; the median relapse-free survival (RFS) was 14 months with a RFS of 54% at 12 months, and 38% at 24 months. For patient with and without Gliadel, median and 1-year RFS were 12.9 months and 52% vs. 14 months and 42%, respectively (p = 0.89). According to pathology, Gliadel did not influence RFS of patients with Grade III or glioblastoma. However, for all patients, in multivariate analysis, non-methylated methylguanine methyltransferase (MGMT) was the only unfavorable prognostic factor of RFS (p = 0.017; HR 2.8; CI [1.2-7]). Median overall survival (OS) was 20.8 months; the OS rate at 12 months was 78.5%, and at 24 months 35.4%. For patients treated with and without Gliadel, median and 1-year OS were 20.6 months and 78.6% vs. 20.8 months and 78.4%, respectively. According to pathology, Gliadel did not influence OS of patients with Grade III or glioblastoma. For all patients, in multivariate analysis, unfavorable prognosticators for OS were non-methylated MGMT (p = 0.001; HR: 6.5; CI [2-20]) and irradiation dose <60 Gy (p = 0.02; HR: 6.3; CI [2-20]). With carmustine wafers, before irradiation, median gross tumor volume plus edema was 84 mL (27-229), whereas it was 68 mL (10-362) without carmustine (p = nonsignificant). Four cases of Grade 3 thrombopenia occurred, all in the carmustine wafer group. Conclusion: In patients with high-grade gliomas, adding Gliadel before performing a Stupp protocol did not improve survival.

    Full Text Available Introduction: Intraoperative radiation therapy device (IORT is one of the several options for partial breast irradiation. IORT is sent to the tumor bed during surgery and can be replaced with conventional standard therapy (EBRT. The aim of this study was to evaluate the safety and effectiveness of IORT machine compared with EBRT and to determine the dominant option in terms of the cost-effectiveness. Method: This study was conducted in two phases; the first phase was a comprehensive review of the electronic databases search that was extracted after extraction and selection of the articles used in this article on effectiveness outcomes. Data collection form was completed by professionals and experts to estimate the cost of treatment, intraoperative radiotherapy and radiotherapy cost when using external radiation therapy process; direct costs were considered from the perspective of service provider and they were calculated in the second phase to determine the option of cost-effective ICER. Excel software was used for data analysis and sensitivity analysis was performed to determine the strength of the results of cost-effectiveness. Results:18 studies were selected but only 8 of them were shown to have acceptable quality. The consequences like “rate of cancer recurrence”, “seroma”, “necrosis”, “toxic”, “skin disorders and delayed wound healing” and “spread the pain” were among the consequences used in the selected articles. The total costs for each patient during a course of treatment for EBRT and IORT were estimated 1398 and $5337.5, respectively. During the analysis, cost-effectiveness of the consequences of cancer recurrence, seroma, necrosis and skin disorders and delayed wound healing ICER was calculated. And IORT was found to be the dominant supplier in all cases. Also, in terms of implications of toxicity and prevalence of pain, IORT had a lower cost and better effectiveness and consequently the result was more cost

    The authors reviewed 24 cerebellar medulloblastoma patients treated at Keio University to determine usefulness of combined chemotherapy including platinum derivatives (cisplatin, carboplatin) as the induction and maintenance treatment. All patients underwent radical surgery and craniospinal irradiation. Ten received adjuvant chemotherapy other than platinum derivatives (mainly with nitrosourea compounds), five were treated by induction and maintenance chemotherapy including platinum derivatives, and nine patients did not undergo chemotherapy. The progression-free survival rate of patients treated with platinum derivatives was better than that of patients treated with other modes of chemotherapy and also that of patients who did not receive chemotherapy. The results were especially good in the case of four patients treated with maintenance chemotherapy consisting of carboplatin and etoposide, two of whom had been free from relapse beyond the risk period of Collins. The occurrences of toxicity in maintenance chemotherapy with carboplatin and etoposide were limited to transient leucopenia. The present study indicates combined chemotherapy including platinum derivatives benefits patients with medulloblastoma, and could be useful, especially as maintenance treatment. (author)

    Gestational trophoblastic neoplasia (GTN) is a highly curable group of pregnancy-related tumours; however, approximately 25% of GTN tumours will be resistant to, or will relapse after, initial chemotherapy. These resistant and relapsed lesions will require salvage chemotherapy with or without surgery. Various salvage regimens are used worldwide. It is unclear which regimens are the most effective and the least toxic.

    To evaluate the contrast enhancement patterns of lung cancer after chemotherapy using a dynamic contrast-enhanced (DCE) CT and to determine whether the enhancement patterns of tumors at early stages of treatment can predict treatment responses. Forty-two patients with advanced lung cancers underwent DCE-CT and follow-up CT after chemotherapy. We evaluated peak and net enhancement (PE and NE, respectively) and time-density curves (TDCs) (type A, B, C, and D) on DCE-CT images. Treatment responses were evaluated using revised Response Evaluation Criteria in Solid Tumor criteria. NE and PE values were significantly higher in the progressive disease (PD) groups than in the stable disease (SD) or partial response (PR) groups (p < 0.05). Types B, C, and D on TDCs were observed mostly in the PR and SD groups (96.0%), whereas type A was most frequent in the SD and PD groups (97.2%), which were significantly different in terms of PE and NE. Contrast enhancement pattern regarding the response of treatment on DCE-CT images could be helpful in predicting treatment response of advanced lung cancer after treatment.

    Neurosurgical craniotomy, craniectomy, or other trans-galeal interventions are performed for a variety of indications, including the resection of benign or malignant tumors, hematoma evacuation, and for the management of intractable seizure disorders. Despite an overall low complication rate of intervention, wound healing complications such as dehiscence, surgical site infection, and cerebrospinal fluid leak are not uncommon. A retrospective review was performed of all patients who underwent scalp incision closure at a single institution by a single plastic surgeon between 2006 and 2013. Sixty patients (83 procedures) were included in the study. Fifty-seven patients (95.0 %) underwent previous craniotomy, craniectomy, or other trans-galeal procedure. Of the total 60 patients, 35 patients received preoperative radiation. Sixteen patients received bevacizumab prior to their index case, while 12 received bevacizumab postoperatively. Ten patients (16.7 %) required additional plastic surgical intervention for wound complications after their index plastic surgery procedure. Plastic surgery was consulted prophylactically in 34 patients (38 procedures). When plastic surgery was consulted prophylactically, 4 patients (11.8 %) required further wound revision. None of the 14 patients who underwent prophylactic plastic surgery closure for previous scalp incision, preoperative bevacizumab, and XRT administration required re-intervention. Plastic surgery closure of complex scalp incisions reduces the incidence of wound complications among patients who underwent previous neurosurgical intervention, XRT administration, and preoperative bevacizumab administration. This is particularly true when plastic surgery closure is performed "prophylactically." Further collaboration between the neurosurgical and plastic surgery teams is therefore warranted, particularly in the setting of these high-risk cases.

    The risk of iatrogenic tumors with radiation therapy is so outweighed by the benefit of cure that estimates of risk have not been considered necessary. However, with the introduction of chemotherapy, combined therapy, and particle radiation therapy, the comparative risks should be examined. In the case of radiation, total dose, fractionation, dose rate, dose distribution, and radiation quality should be considered in the estimation of risk. The biological factors that must be considered include incidence of tumors, latent period, degree of malignancy, and multiplicity of tumors. The risk of radiation induction of tumors is influenced by the genotype, sex, and age of the patient, the tissues that will be exposed, and previous therapy. With chemotherapy the number of cells at risk is usually markedly higher than with radiation therapy. Clearly the problem of the estimation of comparative risks is complex. This paper presents the current views on the comparative risks and the importance of the various factors that influence the estimation of risk.

  1. Studies of the effects of radiation or surgery on the salivary amylase activity and the isoamylase composition in salivary gland tumours

    Sirsat, A.V.; Talavdekar, R.V.; Rajpal, R.M. (Tata Memorial Hospital, Bombay (India))

    The total amylase activity and the isoamylase composition of saliva were studied in patients with salivary gland tumours before and after treatment to evaluate the efficiency of treatment in terms of its ability to restore normal or nearly normal salivary function. The material for the study comprised 35 normal subjects, one case of mumps and eight cases of histologically proved salivary gland tumours, three of which received radiation treatment and one was subjected to total parotidectomy. It is observed that there is a marked deviation from normal in the total salivary amylase activity and the isoamylase pattern in mumps and untreated salivary gland tumours and some increase in amylase activity is noticeable after treatment of these tumours, the increase being more marked after surgery. The salivary isoamylase pattern restored to normal in case of mumps after recovery and in salivary gland tumour after surgery but not after irradiation. These findings suggest that in view of the deleterious effects of radiaton on salivary gland function, surgery is preferable to radiation as the treatment of choice. Further studies are underway to assess the utility of the heat labile salivary amylase fraction obseved in these cases in detecting recurrences.

    A 52-year-old man had bloody stools during chemotherapy for gastric cancer. A colonoscopy revealed necrotizing ulcer-like changes. A biopsy confirmed the presence of amoebic trophozoites. Subsequently,peritonitis with intestinal perforation developed, and emergency peritoneal lavage and colostomy were performed. After surgery, endotoxin adsorption therapy was performed and metronidazole was given. Symptoms of peritonitis and colonitis resolved.with the progression of gastric cancer. The patient died 50 d after surgery. Fulminant amoebic colitis is very rarely associated with chemotherapy. Amoebic colitis should be considered in the differential diagnosis of patients who have bloody stools during chemotherapy.

    In patients with operable esophageal cancer, there is evidence supporting the use of preoperative chemotherapy or preoperative chemoradiation. The addition of radiotherapy to chemotherapy seems more relevant for the more locally advanced cancers. There is a need to examine in trials more modern chemotherapy combinations with and without concurrent radiation and for research into assessing methods for predicting outcomes from neoadjuvant therapy as part of the paradigm of therapy for this disease.

    Trastuzumab (Herceptin) is the first humanized monoclonal antibody targeting the HER2 antigen in breast cancer. HER2 receptor has been individualised 20 years ago. During the past 10 years, trastuzumab administration has radically modified the prognosis of the patients that are treated for HER2 positive breast cancer. Its efficacy has been demonstrated in the metastatic and adjuvant settings. While, trastuzumab based-regimens became the standard of care in the treatment of HER2/neu positive breast cancer, the optimal combination (concurrently or sequentially) to chemotherapy and radiation therapy is still unknown. Indeed, while the concurrent administration of trastuzumab and anthracyclines is not recommended because of a high risk of cardiac toxicity, there is no published data on the best sequence of trastuzumab and radiation therapy administration, particularly when internal mammary chain is involved. The benefit/risk ratio of the concurrent and sequential administration of trastuzumab with chemotherapy and radiation therapy will be discussed in this review. (authors)

    Malignant transformation of giant cell tumors of bones, that is, secondary malignant giant cell tumor of bone, is rare. The most common symptoms are local pain and swelling. There are no prior reports of giant cell tumor of bone with fever of unknown origin at the onset. Here we present a case of a secondary malignant giant cell tumor of bone due to malignant transformation 40 years after surgery without radiation therapy, presenting as fever of unknown origin. A 75-year-old Asian man presented with a 3-week history of continuous pyrexia and left knee pain and swelling. He had been diagnosed at age 35 years with a giant cell tumor of bone of his left distal femur and underwent bone curettage and avascular fibula grafting at that time. Postoperative radiation therapy was not performed. He remained recurrence-free for 40 years after surgery. At age 75, histopathological findings suggested a secondary malignant giant cell tumor of bone. The tumor specimen expressed tumor necrosis factor-α. Neoplastic fever was suspected, and a naproxen test was conducted. His pyrexia showed immediate resolution. Surgery was performed under a diagnosis of a secondary malignant giant cell tumor of bone with neoplastic fever. His pyrexia and inflammatory activities diminished postoperatively. This is the first reported case, to the best of our knowledge, of the detection of a secondary malignant giant cell tumor of bone based on fever of unknown origin after long-term (40 years) follow-up. After curettage and bone grafting, giant cell tumor of bone may transform to malignancies within a few years or even decades after surgery. Therefore, meticulous follow-up is essential. The fever might be attributable to the tumor releasing inflammatory cytokines. Not only pain and swelling but also continuous pyrexia may suggest the diagnosis of a secondary malignant giant cell tumor of bone.

    Purpose Our purpose was to evaluate the impact of post-mastectomy breast reconstruction on the timing of chemotherapy. Methods We included Stage I–III breast cancer patients from eight National Comprehensive Cancer Network institutions for whom guidelines recommended chemotherapy. Surgery type was categorized as breast conserving surgery (BCS), mastectomy alone, mastectomy with immediate reconstruction (M+IR), or mastectomy with delayed reconstruction (M+DR). A Cox regression analysis was used to assess the association between surgery type and timing of chemotherapy initiation. Results Of the 3,643 patients, only 5.1% received it ≥ 8 weeks from surgery. In the multivariate analysis, higher stage, Caucasian and Hispanic race/ethnicity, lower body-mass index and absence of comorbid conditions were all significantly associated with earlier time to chemotherapy. There was also significant interaction between age, surgery and chemotherapy delivery. Among women breast reconstruction does not appear to lead to omission of chemotherapy, but it is associated with a modest, but statistically significant, delay in initiating treatment. For most, it is unlikely that this delay has any clinical significance. PMID:20143440

    Full Text Available Colorectal cancer is one of the leading causes of cancer incidence and mortality. In 2008 inRussian Federation55 719 new cases of colorectal cancer were diagnosed and 37 911 patients died of this disease. A significant progress was achieved in metastatic colorectal cancer treatment during the last decades. A lot of treatment options became available: from 5-fluoruracil monotherapy to combined treatment treatment schemes including surgery. A group of patients with isolated liver metastases was distinguished, who can achieve 5-year survival rate of 40 % after systemic treatment and surgery. Today, based on clinical data and molecular analysis, we come close to individualized treatment of this patient group. In this literature review results of metastatic colorectal cancer chemotherapy are being analyzed and rational treatment tactic is proposed based on therapy goals.

    Chemotherapy stands today for cancer. In 1909, Paul Ehrlich (1854-1915) advocates the use of arsphenamine by infusion. So, he is considered as the father of chemotherapy. In fact, the first to have thought through chemotherapy was Sir Christopher Wren (1632-1723). In 1676, ideas and experiments on animals had sufficiently progressed to allow Michel Ettmuller (1644-1683) to publish the first edition of his book and several others were printed until 1753. In this book, he describes the first intravenous treatment, it sets the first indications, dosages and different products which can be used. However this method has been forgotten until the late 19th century.

    OBJECTIVE To investigate the role of maintenance chemotherapy on stage Ⅲ ovarian carcinoma.METHODS A retrospective analysis was conducted of 47 stage Ⅲ ovarian carcinoma patients with clinical complete remission after first-line chemotherapy. Among these patients, 21 cases were treated with maintenance chemotherapy, while the other 26 cases were free of treatment until progression. The 2 groups were compared with respect to progression-free survival (PFS) and overall survival(OS).RESULTS The median PFS and OS were not significantly different between the 2 groups. For those patients, in a subgroup of suboptimal surgery (residual disease >2 cm), the median PFS was 110 weeks and 56 weeks and the median OS was 223 weeks and 157 weeks for the maintenance and non-treated respectively. Both PFS and OS values favoured the maintenance group, P=0.004 and P=0.015 respectively. In a subgroup of optimal surgery (residual disease ≤2 cm), the differences were not significant.CONCLUSION Patients with stage Ⅲ ovarian carcinoma with clinical complete remission may benefit from maintenance chemotherapy, if the residual disease is >2 cm. To those with a residual disease ≤2 cm, the maintenance chemotherapy maybe of no value. So "individualized maintenance chemotherapy" should be conducted in the clinical setting.

    The development of curative chemotherapy regimens for the treatment of Hodgkin's lymphoma (HL) is one of the true success stories in oncology. Most patients diagnosed with HL today can be cured. The major task remaining before us is curing as many patients as possible with their initial therapeutic approach while minimizing the acute toxicities and limiting the lifetime risks of important secondary events such as cardiovascular complications and secondary malignancies. In the 40 years since DeVita et al. developed the mechlorethamine, vincristine, procarbazine, and prednisone chemotherapy regimen, we have learned a great deal about risk stratification to minimize treatment-related toxicity. Positron emission tomography may further assist us in reducing radiation treatment without compromising cures. This review will discuss the development of the chemotherapy regimens used in the management of early and advanced stage HL and the advantages and disadvantages of their use in combination with radiation therapy.

    Full Text Available Surgery is the only chance for cure in pancreatic ductal adenocarcinoma. In unresectable, locally advanced pancreatic cancer (LAPC, the National Comprehensive Cancer Network (NCCN suggests chemotherapy and consideration for radiation in cases of unresectable LAPC. Here we present a rare case of unresectable LAPC with a complete histopathological response after chemoradiation followed by surgical resection. A 54-year-old female presented to our clinic in December 2013 with complaints of abdominal pain and 30-pound weight loss. An MRI demonstrated a mass in the pancreatic body measuring 6.2×3.2 cm; biopsy revealed proven ductal adenocarcinoma. Due to splenic vein/artery and contiguous celiac artery encasement, she was deemed surgically unresectable. She was started on FOLFIRINOX therapy (three cycles, intensity modulated radiation to a dose of 54 Gy in 30 fractions concurrent with capecitabine, followed by FOLFIRI, and finally XELIRI. After 8 cycles of ongoing XELIRI completed in March 2015, restaging showed a remarkable decrease in tumor size, along with PET-CT revealing no FDG-avid uptake. She was reevaluated by surgery and taken for definitive resection. Histopathological evaluation demonstrated a complete R0 resection and no residual tumor. Based on this patient and literature review, this strategy demonstrates potential efficacy of neoadjuvant chemoradiation with prolonged chemotherapy, followed by surgery, which may improve outcomes in patients deemed previously unresectable.

    To clarify risk factors for breast recurrence of inflammatory type after breast conserving therapy, we examined clinicopathological findings and therapies given after initial surgery. Nine cases of inflammatory breast recurrence out of 133 recurrent cases collected from a collaborative group supported by a grant-in-aid for Cancer Research by Japanese Ministry of Health and Welfare (7-24, Chairman: H. Koyama) were analyzed by a case control study. And forty-three recurrent cases in Kumamoto City Hospital were also analyzed similarly. Inflammatory breast recurrence after breast conserving surgery is characterized as follows: Most cases have negative surgical margin and may be unresponsive to radiation therapy, unlike non-inflammatory breast recurrence. Lymph node metastasis is involved in recurrence, but the difference in patients with only distant metastasis was positive lymphatic invasion. Distant metastasis coexisted at the time of recurrence, and secondary surgery was impossible in most cases. The prognosis after recurrence was unfavorable. These findings suggest that inflammatory recurrence is manifestation of so-called ``occult`` inflammatory breast cancer. (author)

    A retrospective study of gastric adenocarcinoma treated with surgery as curative attempt was performed at the Oncology Service, in the Hospital Regional 20 de Noviembre, ISSSTE. Morbidity and mortality of the surgical procedures were evaluated, the significance of several risk factors and the survival impact of adjuvant chemotherapy with 5-fluorouracil (5-FU) and mitomycin C (MMC). In the period from 1975 to 1991 a total of 483 new cases were seen. In only 54 patients (11.2%) was it possible to undertake a curative resection. The patients were assigned to three groups of treatment: surgery alone (14 cases), surgery + 5-FU (19 cases), and surgery + 5-FU+MMC (21 cases). Three different types of surgical techniques are regularly performed in our service for gastric cancer treatment: Billroth II distal gastrectomy, total gastrectomy with Roux-En-Y reconstruction, and esophagogastrectomy with esophagogastrostomy. Surgical morbidity and mortality was low, with 9% of duodenal stump fistulas and 27% with partial stenosis of esophagojejunostomy; the operative mortality was zero. Chemotherapy toxicity was transient and low, no related deaths were recorded. The prognostic factors associated significantly with survival were lymph node status and tumor penetration. The histologic differentiation as well as the tumor location and type of surgery had no significance. The estimated 5-year survival of the patients treated with surgery alone was 62%, while that of the patients treated with surgery plus chemotherapy was 38%. These groups were not comparable, however, because of important differences in their prognostic factors. The groups treated with 5-FU alone or in combination with MMC had no survival difference between them.(ABSTRACT TRUNCATED AT 250 WORDS)

    Delayed gastric emptying symptoms are often reported after chemotherapy. This study aims to characterise the effects of chemotherapy on gastric neuro-muscular function. Patients undergoing elective surgery for oesophago-gastric cancer were recruited. Acetylcholinesterase, nNOS, ghrelin receptor and motilin expressions were studied in gastric sections from patients receiving no chemotherapy (n = 3) or oesophageal (n = 2) or gastric (n = 2) chemotherapy. A scoring system quantified staining intensity (0-3; no staining to strong). Stomach sections were separately suspended in tissue baths for electrical field stimulation (EFS) and exposure to erythromycin or carbachol; three patients had no chemotherapy; four completed cisplatin-based chemotherapy within 6 weeks prior to surgery. AChE expression was markedly decreased after chemotherapy (scores 2.3 ± 0.7, 0.5 ± 0.2 and 0 ± 0 in non-chemotherapy, oesophageal- and gastric-chemotherapy groups (p gastric function.

    The purpose of this study was to evaluate the risk factors associated with supraclavicular nodal failure (SCF) in patients with one to three positive axillary nodes treated with breast conserving surgery and axillary dissection without supraclavicular node radiation (S/C RT) to aid in the selection of patients for S/C RT. Two hundred two breast conservation patients with one to three positive axillary nodes on axillary dissection treated with breast irradiation without S/C RT and 20 patients with S/C RT between August 1985 and May 2002 were identified and retrospectively evaluated. The Kaplan-Meier method was used to determine SCF-free and overall survival curves. Risk factors for SCF were examined. The median follow-up from surgery was 72 months (range: 4-195). Nine of 202 patients (4%) failed in the ipsilateral breast, 4 (2%) in the ipsilateral supraclavicular lymph nodes, 4 (2%) in the ipsilateral axillary and/or internal mammary nodes and 30 (15%) distantly. The 5- and 10-year SCF-free survival was 97.92%. The overall survival at 5, 10, and 15 years was 91.35%, 75.58%, and 67.18%, respectively. SCFs were associated with high grade or ER negative cancers, but not with number of positive nodes. Two of the four SCFs were associated with distant metastases, and two with local failures. One patient with a SCF was salvaged and is disease-free at 134 months. The overall low incidence of SCF in patients with one to three positive nodes treated with breast radiation alone after breast conserving surgery and adequate axillary dissection suggests that additional S/C RT is unnecessary in this cohort. When it occurs, supraclavicular nodal failure is often associated with distant metastases.

    This prospective study was conducted to determine predictors of epidermal thickening during and after whole-breast radiation therapy (XRT) using objective measurements acquired with ultrasound. After breast-conserving surgery, 70 women received a definitive course of whole-breast XRT (50 Gy plus boost). Prior to XRT, at week 6 of XRT, and 6 weeks after XRT, patients underwent objective ultrasound measurements of epidermal thickness over the lumpectomy cavity and all 4 quadrants of the treated breast. A skin thickness ratio (STRA) was then generated normalizing for corresponding measurements taken of the untreated breast. Baseline measurements indicated that 87% of patients had skin thickening in the treated versus untreated breast (mean increase, 27%; SD, 0.29) prior to XRT. The STRA increased significantly by week 6 of XRT (mean, 25%; SD, 0.46) and continued to increase significantly 6 weeks after XRT (mean, 33%; SD, 0.46) above baseline measurements (Pbreast volume (P=.003) and surgical evaluation of the axilla with full lymph node dissection (Pskin toxicity according to Radiation Therapy Oncology Group grading criteria. This is one of the first studies to objectively document that lymph node surgery affects XRT-induced skin thickening in patients with breast cancer. Surgical evaluation of the axilla with complete lymph node dissection was associated with the most severe XRT-induced skin changes after XRT completion. These results may inform future studies aimed at minimizing side effects of XRT and surgery, particularly when surgical lymph node assessments may not alter breast cancer management or outcome.

    Purpose Despite aggressive therapies, median survival for malignant gliomas is less than 15 months. Patients with unmethylated O6-methylguanine–DNA methyltransferase (MGMT) fare worse, presumably because of temozolomide resistance. AdV-tk, an adenoviral vector containing the herpes simplex virus thymidine kinase gene, plus prodrug synergizes with surgery and chemoradiotherapy, kills tumor cells, has not shown MGMT dependency, and elicits an antitumor vaccine effect. Patients and Methods Patients with newly diagnosed malignant glioma received AdV-tk at 3 × 1010, 1 × 1011, or 3 × 1011 vector particles (vp) via tumor bed injection at time of surgery followed by 14 days of valacyclovir. Radiation was initiated within 9 days after AdV-tk injection to overlap with AdV-tk activity. Temozolomide was administered after completing valacyclovir treatment. Results Accrual began December 2005 and was completed in 13 months. Thirteen patients were enrolled and 12 completed therapy, three at dose levels 1 and 2 and six at dose level 3. There were no dose-limiting or significant added toxicities. One patient withdrew before completing prodrug because of an unrelated surgical complication. Survival at 2 years was 33% and at 3 years was 25%. Patient-reported quality of life assessed with the Functional Assessment of Cancer Therapy-Brain (FACT-Br) was stable or improved after treatment. A significant CD3+ T-cell infiltrate was found in four of four tumors analyzed after treatment. Three patients with MGMT unmethylated glioblastoma multiforme survived 6.5, 8.7, and 46.4 months. Conclusion AdV-tk plus valacyclovir can be safely delivered with surgery and accelerated radiation in newly diagnosed malignant gliomas. Temozolomide did not prevent immune responses. Although not powered for efficacy, the survival and MGMT independence trends are encouraging. A phase II trial is ongoing. PMID:21844505

    Full Text Available The triggers of secondary thrombotic thrombopcytopenic purpura (TTP include drug toxicity, radiation and high-dose chemotherapy, angioinvasive infections, surgery and acute graft versus host disease. TTP secondary to surgery have been reported in a number of cases. Most of the cases have been occurred after open heart surgery. Extensive endothelial damage is held responsible as the initiating mechanism in postoperative TTP cases. However, there is no report of secondary TTP describing development owing to ABO incompatible blood transfusion. Here, we describe a patient who developed TTP after transfusion of ABO incompatible blood during hospitalization for bypass surgery. We also propose a hypothesis which may account for the possible underlying mechanism.

    Full Text Available Ewing′s sarcoma constitutes three per cent of all pediatric malignancies. Ewing′s sarcoma has generally been more responsive to chemotherapy than adult-type sarcomas, and chemotherapy is now recommended for all patients with this disease. It is essential to integrate local control measures in the form of surgery and/or radiotherapy at the appropriate time, along with chemotherapy to eradicate the disease. This approach has improved the survival substantially to the tune of 70% in localized disease, although outcome for metastatic disease remains dismal. Newer therapeutic approaches are required to improve outcome for metastatic and recurrent or refractory Ewing′s sarcoma in organized co-operative group trials.

    Purpose: To evaluate mediastinal nodal clearance (MNC) rates after induction chemotherapy and concurrent, full-dose radiation therapy (RT) in a phase II trimodality trial (Radiation Therapy Oncology Group protocol 0229). Patients and Methods: Patients (n=57) with stage III non-small cell lung cancer (pathologically proven N2 or N3) were eligible. Induction chemotherapy consisted of weekly carboplatin (AUC = 2.0) and paclitaxel 50 mg/m{sup 2}. Concurrent RT was prescribed, with 50.4 Gy to the mediastinum and primary tumor and a boost of 10.8 Gy to all gross disease. The mediastinum was pathologically reassessed after completion of chemoradiation. The primary endpoint of the study was MNC, with secondary endpoints of 2-year overall survival and postoperative morbidity/mortality. Results: The grade 3/4 toxicities included hematologic 35%, gastrointestinal 14%, and pulmonary 23%. Forty-three patients (75%) were evaluable for the primary endpoint. Twenty-seven patients achieved the primary endpoint of MNC (63%). Thirty-seven patients underwent resection. There was a 14% incidence of grade 3 postoperative pulmonary complications and 1 30-day, postoperative grade 5 toxicity (3%). With a median follow-up of 24 months for all patients, the 2-year overall survival rate was 54%, and the 2-year progression-free survival rate was 33%. The 2-year overall survival rate was 75% for those who achieved nodal clearance, 52% for those with residual nodal disease, and 23% for those who were not evaluable for the primary endpoint (P=.0002). Conclusions: This multi-institutional trial confirms the ability of neoadjuvant concurrent chemoradiation with full-dose RT to sterilize known mediastinal nodal disease.

    Purpose Chemotherapy with alternating vincristine-doxorubicin-cyclophosphamide and ifosfamide-etoposide cycles and primary tumor treatment with surgery and/or radiation therapy constitute the usual approach to localized Ewing sarcoma in North America. We tested whether chemotherapy intensification through interval compression could improve outcome. Patients and Methods This was a prospective, randomized controlled trial for patients younger than 50 years old with newly diagnosed localized extradural Ewing sarcoma. Patients assigned to standard and intensified treatment were to begin chemotherapy cycles every 21 and 14 days, respectively, provided an absolute neutrophil count greater than 750 × 106/L and a platelet count greater than 75 × 109/L. Patients received vincristine (2 mg/m2), doxorubicin (75 mg/m2), and cyclophosphamide (1.2 g/m2) alternating with ifosfamide (9 g/m2) and etoposide (500 mg/m2) for 14 cycles, with filgrastim (5 mg/kg per day; maximum, 300 mg) between cycles. Primary tumor treatment (surgery, radiation, or both) was to begin at week 13 (after four cycles in the standard arm and six cycles in the intensified arm). The primary end point was event-free survival (EFS). The study is registered at ClinicalTrials.gov (identifier: NCT00006734). Results Five hundred eighty-seven patients were enrolled and randomly assigned, and 568 patients were eligible, with 284 patients in each regimen. For all cycles, the median cycle interval for standard treatment was 21 days (mean, 22.45 days); for intensified treatment, the median interval was 15 days (mean, 17.29 days). EFS at a median of 5 years was 65% in the standard arm and 73% in the intensified arm (P = .048). The toxicity of the regimens was similar. Conclusion For localized Ewing sarcoma, chemotherapy administered every 2 weeks is more effective than chemotherapy administered every 3 weeks, with no increase in toxicity. PMID:23091096

    Diagnostic imaging is pivotal in the initial detection, characterization, staging and post-treatment follow-up of patients with high-grade osteogenic and Ewing`s sarcoma. In the present review article, conventional and new imaging modalities are discussed with regard to the monitoring of the effect of neoadjuvant chemotherapy in such patients. Presurgical monitoring of response to chemotherapy may have an impact on modification of neoadjuvant treatment protocols, on patient selection for the performance and timing of limb-salvage surgery and on planning of radiation therapy (in non-operated Ewing`s sarcomas) and selection of postoperative chemotherapy regimens. Dynamic contrast-enhanced MR imaging, as part of a routine MR protocol, assists in the detection of the most viable parts of the tumour and serves as an initial standard for follow-up of the metabolic activity of the tumour during and after chemotherapy, both in small intraosseous tumours and in tumours with an associated soft tissue mass. In combination with selected morphological features, dynamic imaging parameters are therefore advocated for monitoring the effect of neoadjuvant chemotherapy in patients with osteogenic and Ewing`s sarcoma.

    In colorectal cancer (CRC), unresectable liver metastases are associated with a poor prognosis. The FOXFIRE (an open-label randomized phase III trial of 5-fluorouracil, oxaliplatin, and folinic acid +/- interventional radioembolization as first-line treatment for patients with unresectable liver-only or liver-predominant metastatic colorectal cancer), SIRFLOX (randomized comparative study of FOLFOX6m plus SIR-Spheres microspheres versus FOLFOX6m alone as first-line treatment in patients with nonresectable liver metastases from primary colorectal carcinoma), and FOXFIRE-Global (assessment of overall survival of FOLFOX6m plus SIR-Spheres microspheres versus FOLFOX6m alone as first-line treatment in patients with nonresectable liver metastases from primary colorectal carcinoma in a randomized clinical study) clinical trials were designed to evaluate the efficacy and safety of combining first-line chemotherapy with selective internal radiation therapy (SIRT) using yttrium-90 resin microspheres, also called transarterial radioembolization. The aim of this analysis is to prospectively combine clinical data from 3 trials to allow adequate power to evaluate the impact of chemotherapy with SIRT on overall survival. Eligible patients are adults with histologically confirmed CRC and unequivocal evidence of liver metastases which are not treatable by surgical resection or local ablation with curative intent at the time of study entry. Patients may also have limited extrahepatic metastases. Final analysis will take place when all participants have been followed up for a minimum of 2 years. Efficacy and safety estimates derived using individual participant data (IPD) from SIRFLOX, FOXFIRE, and FOXFIRE-Global will be pooled using 2-stage prospective meta-analysis. Secondary outcome measures include progression-free survival (PFS), liver-specific PFS, health-related quality of life, response rate, resection rate, and adverse event profile.

    The objective of the study was to evaluate the effect of neoadjuvant chemotherapy on the survival of patients with oropharyngeal cancer. Patients with a squamous cell carcinoma of the oropharynx for whom curative radiotherapy or surgery was considered feasible were entered in a multicentric randomized trial comparing neoadjuvant chemotherapy followed by loco-regional treatment to the same loco-regional treatment without chemotherapy. The loco-regional treatment consisted either of surgery plus radiotherapy or of radiotherapy alone. Three cycles of chemotherapy consisting of Cisplatin (100 mg/m2) on day 1 followed by a 24-hour i.v. infusion of fluorouracil (1000 mg/m2/day) for 5 days were delivered every 21 days. 2–3 weeks after the end of chemotherapy, local treatment was performed. The trial was conducted by the Groupe d'Etude des Tumeurs de la Tête Et du Cou (GETTEC). A total of 318 patients were enrolled in the study between 1986 and 1992. Overall survival was significantly better (P = 0.03) in the neoadjuvant chemotherapy group than in the control group, with a median survival of 5.1 years versus 3.3 years in the no chemotherapy group. The effect of neoadjuvant chemotherapy on event-free survival was smaller and of borderline significance (P = 0.11). Stratification of the results on the type of local treatment, surgery plus radiotherapy or radiotherapy alone, did not reveal any heterogeneity in the effect of chemotherapy. © 2000 Cancer Research Campaign http://www.bjcancer.com PMID:11189100

    Antineoplastic chemotherapy (CT) represents the systemic treatment of malignant tumors. It can be used alone or combined with surgery and / or radiotherapy. The cytotoxic agents used in chemotherapy work on both cancerous cells and noncancerous cells of the body, generally resulting in high toxicity. The biological aggressiveness of chemotherapy particularly affects rapidly replicating cells, such as those of the digestive tract, resulting in adverse effects that impair food intake, leading to compromised nutritional status and which may lead to cachexia. The main toxic effects of chemotherapy in the gastrointestinal tract include nausea, vomiting -these are the most frequent- constipation, diarrhea, xerostomia, mucositis, dysphagia and anorexia. Given the high frequency of such effects, nutritional intervention should be an integral part of cancer treatment, to maintain and/or improve the patient's nutritional status and reduce or minimize the side effects caused by treatment. Accordingly, the goal of this study is to review dietetic conduct in the process of caring for patients undergoing cancer chemotherapy.

    2014-01-01

    The optimal antiretroviral therapy (ART) regimen for human immunodeficiency virus (HIV)–infected patients with cancer remains unknown, as clinical trials are lacking and published data are insufficient to guide recommendations. When concomitant use of chemotherapy and ART is anticipated, overlap of toxic effects and drug–drug interactions between chemotherapy and ART may alter the optimal choice of ART. Prospective studies are urgently needed to further define the toxic effects of combined chemotherapy and ART in HIV-positive cancer patients. Such studies should aid the development of guidelines for treatment of this population. For now, clinicians should individualize decisions regarding treatment of HIV according to clinical and laboratory findings, cancer treatment plan (chemotherapy, radiotherapy, or surgery), liver or renal disease, potential adverse drug effects (eg, rash, gastrointestinal intolerance, bone marrow suppression), and patient preference. This review focuses on what infectious disease specialists need to know to select the most appropriate ART regimens for patients receiving chemotherapy. PMID:24642555

    Purpose: To evaluate the association between radiation pneumonitis and dose-volume histogram parameters and to provide practical guidelines to prevent radiation pneumonitis following radiotherapy administered for breast cancer including internal mammary lymph nodes. Materials and Methods: Twenty patients with early breast cancer who underwent a partial mastectomy were involved in this study. The entire breast, supraclavicular lymph nodes, and internal mammary lymph nodes were irradiated with a dose of 50.4 Gy in 28 fractions. Radiation pneumonitis was assessed by both radiological pulmonary change (RPC) and by evaluation of symptomatic radiation pneumonitis. Dose-volume histogram parameters were compared between patients with grade <2 RPC and those with grade {>=}2 RPC. The parameters were the mean lung dose, V10 (percent lung volume receiving equal to and more than 10 Gy), V20, V30, V40, and normal tissue complication probability (NTCP). Results: Of the 20 patients, 9 (45%) developed grade 2 RPC and 11 (55%) did not develop RPC (grade 0). Only one patient developed grade 1 symptomatic radiation pneumonitis. Univariate analysis showed that among the dose-volume histogram parameters, NTCP was significantly different between the two RPC grade groups (p <0.05). Fisher's exact test indicated that an NTCP value of 45% was appropriate as an RPC threshold level. Conclusion: This study shows that NTCP can be used as a predictor of RPC after radiotherapy of the internal mammary lymph nodes in breast cancer. Clinically, it indicates that an RPC is likely to develop when the NTCP is greater than 45%.

    Purpose: To describe voice and speech quality changes and their predictors in patients with locally advanced oropharyngeal cancer treated on prospective clinical studies of organ-preserving chemotherapy–intensity modulated radiation therapy (chemo-IMRT). Methods and Materials: Ninety-one patients with stage III/IV oropharyngeal cancer were treated on 2 consecutive prospective studies of definitive chemoradiation using whole-field IMRT from 2003 to 2011. Patient-reported voice and speech quality were longitudinally assessed from before treatment through 24 months using the Communication Domain of the Head and Neck Quality of Life (HNQOL-C) instrument and the Speech question of the University of Washington Quality of Life (UWQOL-S) instrument, respectively. Factors associated with patient-reported voice quality worsening from baseline and speech impairment were assessed. Results: Voice quality decreased maximally at 1 month, with 68% and 41% of patients reporting worse HNQOL-C and UWQOL-S scores compared with before treatment, and improved thereafter, recovering to baseline by 12-18 months on average. In contrast, observer-rated larynx toxicity was rare (7% at 3 months; 5% at 6 months). Among patients with mean glottic larynx (GL) dose ≤20 Gy, >20-30 Gy, >30-40 Gy, >40-50 Gy, and >50 Gy, 10%, 32%, 25%, 30%, and 63%, respectively, reported worse voice quality at 12 months compared with before treatment (P=.011). Results for speech impairment were similar. Glottic larynx dose, N stage, neck dissection, oral cavity dose, and time since chemo-IMRT were univariately associated with either voice worsening or speech impairment. On multivariate analysis, mean GL dose remained independently predictive for both voice quality worsening (8.1%/Gy) and speech impairment (4.3%/Gy). Conclusions: Voice quality worsening and speech impairment after chemo-IMRT for locally advanced oropharyngeal cancer were frequently reported by patients, underrecognized by clinicians, and

    Functional tumor volume (FTV) and total lesion glycolysis (TLG) are measures of metabolic activity of tumors determined by fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT images. These parameters could potentially have clinical value in response to treatment evaluation and disease prognostication. The objectives of this study were to investigate the relationship between functional tumor parameters (FTV and TLG) and clinical outcomes in patients with colorectal cancer liver metastases (CRCLM) undergoing {sup 90}Y-resin microsphere selective internal radiation therapy (SIRT) (SIR-Spheres {sup registered}, Sirtex Medical Limited, Lane Cove, NSW, Australia). FDG PET/CT studies of 20 patients with unresectable CRCLM who underwent {sup 90}Y SIRT under a phase II clinical trial were analyzed. FTV and TLG were calculated using PET VCAR (GE Healthcare, Milwaukee, WI, USA) on pretreatment and 4-week posttreatment scans. The effects of pretreatment and posttreatment functional tumor activity on patient survival were evaluated using Kaplan-Meier survival curves. The median survival in the study group was 14.8 months (range 2.0-27.7 months). The median survival for patients with pretreatment FTV values of above and below 200 cc were 11.2 and 26.9 months, respectively (p < 0.05). The median survival for patients with 4-week posttreatment FTV values of above and below 30 cc were 10.9 and 26.9 months, respectively (p < 0.05). The median survival for patients with pretreatment TLG values of above and below 600 g were 11.2 and 26.9 months, respectively (p < 0.05). The median survival for patients with 4-week posttreatment TLG values of above and below 100 g were 10.9 and 26.9 months, respectively (p < 0.05). Pretreatment and posttreatment FTV and TLG showed very strong association with survival. These values can be useful quantitative criteria for patient selection and disease prognostication when {sup 90}Y SIRT is contemplated in patients with CRCLM. (orig.)

    Full Text Available Abstract Background The treatment strategy for gastric diffuse large cell lymphoma (DLBCL has not been standardized in such as to the cycles of chemotherapy, dose of radiation, or necessity for the surgery. Although the results of CHOP or R-CHOP treatments have demonstrated the good prognosis, the treatments have been controversial in many cases. Methods We retrospectively analyzed 40 gastric DLBCL patients receiving chemotherapy with or without radiation in our institute. Those in stages II-IV were treated with six cycles of R-CHOP without radiation; for those in stage I, we administered three cycles of R-CHOP with radiation. Results The three-year overall survival (OS and progression-free survival (PFS rates were 95.2 and 91.8%, respectively. Those in stage I obtained 100% of OS. The radiation dose prescribed was 30.6 Gy for CR cases and 39.6 to 40 Gy for PR after chemotherapy. Although survival rates tended to correlate with staging groups or age-adjusted IPI classifications, multivariate statistical analysis did not show clear differences. All 14 patients with initial bleeding were successfully managed without surgery during treatment. Conclusion R-CHOP therapy was very effective for gastric DLBCL. It may be not necessary to use more than 30.6 Gy of radiotherapy in the highly chemo-sensitive cases. Less toxic treatments should be made available to gastric DLBCL patients.

    SUMMARY Purpose This study was aimed at assessing the effectiveness and the importance of an oral hygiene (OH) protocol in patients undergoing radiation therapy and chemotherapy after prosthesis rehabilitation, in order to reduce or minimize oral complications. Materials and methods This study was carried out at the Department of Dental Science, at the University of Bari-Italy from December 2012 to December 2015 on 34 selected patients with primary oral cancer undergoing chemotherapy and radiotherapy after prosthesis rehabilitation. They were divided into 2 groups according to their age, sex and cancer therapy. Seventeen patients were assigned to the control group and seventeen in the experimental one. In the experimental group (Table 1), patients underwent an oral hygiene protocol whereas in the control group (Table 2) patients received the usual care provided within the clinical setting. All the patients gave written informed consent. It has been asked and obtained the authorisation from the Ethics Committee of the Dental Science and Surgery Department. Results Results show that in patients undergoing the oral hygiene protocol, the complications and the risks of infection and permanent dental problems have been minimized. Indeed, of the seventeen patients undergoing the OH protocol, 70% obtained positive results and were satisfied with the program outcome. Conclusions The role of the health care providers is essential to educate patients to adhere to the prescribed treatments and reinforce their motivation in oral hygiene. The oral hygiene procedures prevent and ameliorate oral complications due to the radiation therapy and chemotherapy. PMID:28280537

    To explore the impact of treatment modality on survival in patients with brain metastases from epithelial ovarian cancer. We conducted a retrospective review of cases of ovarian cancer with brain metastases treated at institutions in three countries (Canada, China, and India) and conducted a search for studies regarding brain metastases in ovarian cancer reporting survival related to treatment modality. Survival was analyzed according to treatment regimens involving (1) some form of surgical excision or gamma-knife radiation with or without other modalities, (2) other modalities without surgery or gamma-knife radiation, or (3) palliation only. Twelve patients (mean age 56 years) with detailed treatment/outcome data were included; five were from China, four from Canada, and three from India. Median time from diagnosis of ovarian cancer to brain metastasis was 19 months (range 10 to 37 months), and overall median survival time from diagnosis of ovarian cancer was 38 months (13 to 82 months). Median survival time from diagnosis of brain metastasis was 17 months (1 to 45 months). Among patients who had multimodal treatment including gamma-knife radiotherapy or surgical excision, the median survival time after the identification of brain metastasis was 25.6 months, compared with 6.0 months in patients whose treatment did not include this type of focused localized modality (P = 0.006). Analysis of 20 studies also indicated that use of gamma-knife radiotherapy and excisional surgery in multi-modal treatment resulted in improved median survival interval (25 months vs. 6.0 months, P gamma-knife radiotherapy and surgical excision.

    With longer survival time of cancer patients, spine metastasis is of growing importance. Management of spine metastasis is quite complicated. Advances in research, surgical techniques and radiosurgical implementation have altered drastically the treatment paradigm for spine metastasis. At present, multi-disciplinary therapy including orthopedics, oncology, radiation oncology, neurosurgery and other disciplines are recommended. Radiation therapy has been proven effective to relieve the pain of spinal metastases. In patients with severe spinal metastases, who is unfavorable for operation, radiotherapy is preferred. Radiation therapy can be used alone or combined with chemotherapy and surgery. Stereotactic radiotherapy makes up for the deficiency of the traditional radiation therapy, giving maximum radiation dose to tumors on the premise of suitable surrounding organ tolerance. Traditional external radiation therapy, brachytherapy, intensity-modulated radiotherapy, stereotactic radiotherapy are commonly used. Radiation therapy of spinal metastases will be reviewed in this paper.

    To investigate the utility of acoustic radiation force impulse (ARFI) imaging, with the determination of shear wave velocity (SWV), to differentiate non-alcoholic fatty liver disease (NAFLD) from non-alcoholic steatohepatitis (NASH) in patients with morbid obesity before bariatric surgery. Thirty-two patients with morbid obesity were evaluated with ARFI and conventional ultrasound before bariatric surgery. The ARFI and ultrasound results were compared with liver biopsy findings, which is the reference standard. The patients were classed according to their histological findings into three groups: group A, simple steatosis; group B, inflammation; and group C, fibrosis. The median SWV was 1.57 {+-} 0.79 m/s. Hepatic alterations were observed in the histopathological findings for all the patients in the study (100 %), with the results of the laboratory tests proving normal. Differences in SWV were also observed between groups A, B and C: 1.34 {+-} 0.90 m/s, 1.55 {+-} 0.79 m/s and 1.86 {+-} 0.75 m/s (P < 0.001), respectively. The Az for differentiating NAFLD from NASH or fibrosis was 0.899 (optimal cut-off value 1.3 m/s; sensitivity 85 %; specificity 83.3 %). The ARFI technique is a useful diagnostic tool for differentiating NAFLD from NASH in asymptomatic patients with morbid obesity. (orig.)

    Purpose: Concurrent chemo-radiation therapy (CCRT) has become a more common cancer treatment option with a better tumor control rate for several tumor sites, including head and neck and lung cancer. In this work, possible optimal chemotherapy schedules were investigated by implementing chemotherapy cell-kill into a tumor response model of RT. Methods: The chemotherapy effect has been added into a published model (Jeong et al., PMB (2013) 58:4897), in which the tumor response to RT can be simulated with the effects of hypoxia and proliferation. Based on the two-compartment pharmacokinetic model, the temporal concentration of chemotherapy agent was estimated. Log cell-kill was assumed and the cell-kill constant was estimated from the observed increase in local control due to concurrent chemotherapy. For a simplified two cycle CCRT regime, several different starting times and intervals were simulated with conventional RT regime (2Gy/fx, 5fx/wk). The effectiveness of CCRT was evaluated in terms of reduction in radiation dose required for 50% of control to find the optimal chemotherapy schedule. Results: Assuming the typical slope of dose response curve (γ50=2), the observed 10% increase in local control rate was evaluated to be equivalent to an extra RT dose of about 4 Gy, from which the cell-kill rate of chemotherapy was derived to be about 0.35. Best response was obtained when chemotherapy was started at about 3 weeks after RT began. As the interval between two cycles decreases, the efficacy of chemotherapy increases with broader range of optimal starting times. Conclusion: The effect of chemotherapy has been implemented into the resource-conservation tumor response model to investigate CCRT. The results suggest that the concurrent chemotherapy might be more effective when delayed for about 3 weeks, due to lower tumor burden and a larger fraction of proliferating cells after reoxygenation.

    Brachytherapy in the treatment of locally advanced cervical cancer has changed substantially because of the introduction of combined intracavitary/interstitial applicators and an adaptive target concept, which is the focus of the prospective, multi-institutional EMBRACE study (www.embracestudy.dk) on image-guided adaptive brachytherapy (IGABT). So far, little has been reported about the development of early to late vaginal morbidity in the frame of IGABT. Therefore, the aim of the present EMBRACE analysis was to evaluate the manifestation pattern of vaginal morbidity during the first 2 years of follow-up. In total, 588 patients with a median follow-up time of 15 months and information on vaginal morbidity were included. Morbidity was prospectively assessed at baseline, every 3 months during the first year, and every 6 months in the second year according to the Common Terminology Criteria for Adverse Events, version 3, regarding vaginal stenosis, dryness, mucositis, bleeding, fistula, and other symptoms. Crude incidence rates, actuarial probabilities, and prevalence rates were analyzed. At 2 years, the actuarial probability of severe vaginal morbidity (grade ≥3) was 3.6%. However, mild and moderate vaginal symptoms were still pronounced (grade ≥1, 89%; grade ≥2, 29%), of which the majority developed within 6 months. Stenosis was most frequently observed, followed by vaginal dryness. Vaginal bleeding and mucositis were mainly mild and infrequently reported. Severe vaginal morbidity within the first 2 years after definitive radiation (chemo)therapy including IGABT with intracavitary/interstitial techniques for locally advanced cervical cancer is limited and is significantly less than has been reported from earlier studies. Thus, the new adaptive target concept seems to be a safe treatment with regard to the vagina being an organ at risk. However, mild to moderate vaginal morbidity is still pronounced with currently applied IGABT, and it needs further attention

    In patients with advanced or recurrent breast cancer, it is difficult to reconstruct chest wall ulcers due to postoperative irradiation, which is often infected. We present a laparoscopic technique for creating and mobilizing an omental flap. A 63-year-old woman diagnosed with parasternal lymph node metastases from left breast cancer 11 months after standard radical mastectomy underwent lymph node resection with radiation therapy. She developed ulceration of the irradiated chest wall 3 years and 10 months later. An omental flap obtained by laparoscopy was used to fill the space after the radiation-induced ulcer was resected and covered with a free skin graft. The skin graft adapted to the omentum. This laparoscopic procedure is more cosmetrically acceptable and less invasive than laparotomy in obtaining the omentum while yielding equivalent results in chest wall reconstruction. (author)

    Endoscopic laser surgery provides an advantageous alternative to Argon Plasma Coagulation, endoscopic tweezers or electro-ablation in gastroenterology that facilitates a selective ablation of stomach tumors with an additional hemostatic effect in the surrounding tissue. This coagulation effect can also be employed for the treatment of gastric ulcers. It is mandatory to control the laser parameters regardless of the desired effect, either cancerous tissue ablation or coagulation to prevent ulcerous bleeding, in order to avoid stomach wall perforation or an insufficient therapeutic outcome. Dosimetric models constitute an attractive tool to determine the proper light dose in order to offer a customized therapy planning that optimizes the treatment results. In this work, a model for Nd:YAG laser surgery is applied to predict both the coagulation zone in gastric ulcers and the removal in adenocarcinomas under different laser setups. Results show clear differences in the effective zone of the gastric malignancy affected by both coagulation and ablation. Therefore the current model could be employed in the clinical practice to plan the optimal laser beam parameters to treat a certain type of pathologic stomach tissue with variable morphology and without risk of perforation or undertreated parts.

    Cancer therapies can be associated with significant central nervous system (CNS) toxicity. While radiation-induced brain damage has been long recognized both in pediatric and adult cancer patients, CNS toxicity from chemotherapy has only recently been acknowledged. Clinical studies suggest that the most frequent neurotoxic adverse effects associated with chemotherapy include memory and learning deficits, alterations of attention, concentration, processing speed and executive function. Preclinical studies have started to shed light on how chemotherapy targets the CNS both on cellular and molecular levels to disrupt neural function and brain plasticity. Potential mechanisms include direct cellular toxicity, alterations in cellular metabolism, oxidative stress, and induction of pro-inflammatory processes with subsequent disruption of normal cellular and neurological function. Damage to neural progenitor cell populations within germinal zones of the adult CNS has been identified as one of the key mechanisms by which chemotherapy might exert long-lasting and progressive neurotoxic effects. Based on the important role of the hippocampus for maintenance of brain plasticity throughout life, several experimental studies have focused on the study of chemotherapy effects on hippocampal neurogenesis and associated learning and memory. An increasing body of literature from both animal studies and neuroimaging studies in cancer patients suggests a possible relationship between chemotherapy induced hippocampal damage and the spectrum of neurocognitive deficits and mood alterations observed in cancer patients. This review aims to briefly summarize current preclinical and neuroimaging studies that are providing a potential link between the neurotoxic effects of chemotherapy and hippocampal dysfunction, highlighting challenges and future directions in this field of investigation.

    Purpose: Whole-breast radiation therapy (XRT) after breast-conserving surgery (BCS) for ductal carcinoma in situ (DCIS) may decrease the risk of local recurrence, but the optimal dose regimen remains unclear. Past studies administered 50 Gy in 25 fractions (conventional); however, treatment pattern studies report that hypofractionated (HF) regimens (42.4 Gy in 16 fractions) are frequently used. We report the impact of HF (vs conventional) on the risk of local recurrence after BCS for DCIS. Methods and Materials: All women with DCIS treated with BCS and XRT in Ontario, Canada from 1994 to 2003 were identified. Treatment and outcomes were assessed through administrative databases and validated by chart review. Survival analyses were performed. To account for systematic differences between women treated with alternate regimens, we used a propensity score adjustment approach. Results: We identified 1609 women, of whom 971 (60%) received conventional regimens and 638 (40%) received HF. A total of 489 patients (30%) received a boost dose, of whom 143 (15%) received conventional radiation therapy and 346 (54%) received HF. The median follow-up time was 9.2 years. The median age at diagnosis was 56 years (interquartile range [IQR], 49-65 years). On univariate analyses, the 10-year actuarial local recurrence–free survival was 86% for conventional radiation therapy and 89% for HF (P=.03). On multivariable analyses, age <45 years (hazard ratio [HR] = 2.4; 95% CI: 1.6-3.4; P<.0001), high (HR=2.9; 95% CI: 1.2-7.3; P=.02) or intermediate nuclear grade (HR=2.7; 95% CI: 1.1-6.6; P=.04), and positive resection margins (HR=1.4; 95% CI: 1.0-2.1; P=.05) were associated with an increased risk of local recurrence. HF was not significantly associated with an increased risk of local recurrence compared with conventional radiation therapy on multivariate analysis (HR=0.8; 95% CI: 0.5-1.2; P=.34). Conclusions: The risk of local recurrence among individuals treated with HF regimens

  15. Cancer immunotherapy with surgery

    1977-08-01

    Full Text Available With the recent advances in the immunological surveillance system, an understanding of the role of host immunity has become essential to the management of carcinogenesis, tumor proliferation, recurrence and metastasis. Although it is important to continue chemical and surgical treatment of cancer, support of the anti-tumor immune system of the host should also be considered. Long term remission has been reported in leukemia by treating with BCG after chemotherapy whereas surgical treatment is usually more effective in preventing cancer recurrence in digestive organ cancer. The first step is extirpating the tumor as thoroughly as possible and the second step is chemo-immunotherapy. Cancer immunity, however weak, constitutes the basis for other treatments in selectively attacking cancer cells remaining after surgery, chemotherapy or irradiation. Immunotherapy should thus not replace chemotherapy or radiotherapy, but these methods should be employed in combination to attain more favorable results.

    The National Institute of Neurology and Neurosurgery in Mexico City has acquired a Novalis® shaped beam radiosurgery unit. The institute is pioneer in the use of new technologies for neuroscience. The Novalis® unit allows the use of conformal beam radiosurgery/therapy and the more advanced modality of conformal therapy: Intensity Modulated Radiation Therapy (IMRT). In the present work we present the first cases of treatments that use the IMRT technique and show its ability to protect organs at risk, such as brainstem and optical vias.

    There is accumulating clinical evidence that chemotherapeutic agents induce neurological side effects, including memory deficits and mood disorders, in cancer patients who have undergone chemotherapeutic treatments. This review focuses on chemotherapy-induced neurodegeneration and hippocampal dysfunctions and related mechanisms as measured by in vivo and in vitro approaches. These investigations are helpful in determining how best to further explore the causal mechanisms of chemotherapy-induced neurological side effects and in providing direction for the future development of novel optimized chemotherapeutic agents.

    A 46-year-old man had surgery for a mixed glioma of the frontotemporal lobe. Postoperatively he received 50 Gy of irradiation. Sixteen months later he developed left hemiparesis and left facial palsy. MRI revealed lesion brain stem and basal ganglia. Despite chemotherapy and an additional 50 Gy dose, the patient deteriorated. Autopsy revealed a wide spread radiation-induced necrosis in the right cerebral hemisphere, midbrain and pons. In radiation therapy, great care must be taken to protect the normal brain tissue. (author).

    Prior to the recent therapeutic advances, chemotherapy was the mainstay of treatment options for advanced-stage melanoma. A number of studies have investigated various chemotherapy combinations in order to expand on the clinical responses achieved with single-agent dacarbazine, but these have not demonstrated an improvement in overall survival. Similar objective responses were observed with the combination of carboplatin and paclitaxel as were seen with single-agent dacarbazine. The combination of chemotherapy and immunotherapy, known as biochemo-therapy, has shown high clinical responses; however, biochemo-therapy has not been shown to improve overall survival and resulted in increased toxicities. In contrast, palliation and long-term responses have been observed with localized treatment with isolated limb perfusion or infusion in limb-isolated disease. Although new, improved therapeutic options exist for first-line management of advanced-stage melanoma, chemotherapy may still be important in the palliative treatment of refractory, progressive, and relapsed melanoma. We review the various chemotherapy options available for use in the treatment and palliation of advanced-stage melanoma, discuss the important clinical trials supporting the treatment recommendations, and focus on the clinical circumstances in which treatment with chemotherapy is useful.

    The O-arm system has recently been introduced and has the capability of combined two-dimensional (2-D) fluoroscopy imaging and three-dimensional computed tomography imaging. In this study, an orthopaedic surgical procedure using C-arm and O-arm systems in their 2-D fluoroscopy modes was simulated and the radiation doses to susceptible organs to which operators can be exposed were investigated. The experiments were performed in four configurations of the location of the X-ray source and detector. Shielding effects on the thyroid surface and the direct exposure delivered to the surgeon's hands were also compared. The results obtained show that the O-arm delivered higher doses to the sensitive organs of the operator in all configurations. The thyroid shield cut-off 89 % of the dose in the posteroanterior configuration of both imaging systems. Thus, the operators need to pay more attention to managing radiation exposure, especially when using the O-arm system.

    There are many questions that have to be answered concerning the role of radiotherapy in the management of primary breast cancer. Hopefully, prospective clinical trials will provide some answers, but more basic research into the biology of breast cancer and the host-tumor relationship will be needed. There are indications that radiotherapy alone, or following minimal extirpative surgery in selected cases, may be as effective for control of breast cancer as conventional mastectomies. The role of radiotherapy following segmental mastectomy, with or without axillary dissection, needs to be clarified. The possibility exists that high LET (linear energy transfer) radiation such as neutron or pi meson beams may provide better local control than conventional radiation. Thus, it may be possible to treat effectively all primary breast cancers with such radiations and obviate the need for any type of mastectomy. It remains to be demonstrated whether adjuvant chemotherapy is as effective as radiotherapy in preventing chest wall and regional node recurrences. If it is not, there may be a place for both adjuvant chemotherapy and radiotherapy in the treatment of operable cancer of the breast. Likewise, effective chemotherapy combined with radiotherapy may increase the local and regional control achieved with radiotherapy alone and make more primary lesions suitable for treatment without mastectomy. Meyer (1970) recently called attention to the leukopenia and cellualr immune deficiency produced by irradiation to the thorax and mediastinum. Further study is necessary to define exactly how much immunosuppression results from radiotherapy, its clinical significance and what can be done to avoid or counter it. If Stjervsward's thesis (1974) concerning the deleterious effects of radiotherapy on survival is correct, then it is of great importance to identify those patients most likely to be adversely affected by radiotherapy. Conversely, it may be possible in the future to identify a

    To evaluate the positioning accuracies of two image-guided localization systems, ExacTrac and On-Board Imager (OBI), in a stereotactic treatment unit. An anthropomorphic pelvis phantom with eight internal metal markers (BBs) was used. The center of one BB was set as plan isocenter. The phantom was set up on a treatment table with various initial setup errors. Then, the errors were corrected using each of the investigated systems. The residual errors were measured with respect to the radiation isocenter using orthogonal portal images with field size 3 × 3 cm(2). The angular localization discrepancies of the two systems and the correction accuracy of the robotic couch were also studied. A pair of pre- and post-cone beam computed tomography (CBCT) images was acquired for each angular correction. Then, the correction errors were estimated by using the internal BBs through fiducial marker-based registrations. The isocenter localization errors (μ ±σ) in the left/right, posterior/anterior, and superior/inferior directions were, respectively, -0.2 ± 0.2 mm, -0.8 ± 0.2 mm, and -0.8 ± 0.4 mm for ExacTrac, and 0.5 ± 0.7 mm, 0.6 ± 0.5 mm, and 0.0 ± 0.5 mm for OBI CBCT. The registration angular discrepancy was 0.1 ± 0.2° between the two systems, and the maximum angle correction error of the robotic couch was 0.2° about all axes. Both the ExacTrac and the OBI CBCT systems showed approximately 1 mm isocenter localization accuracies. The angular discrepancy of two systems was minimal, and the robotic couch angle correction was accurate. These positioning uncertainties should be taken as a lower bound because the results were based on a rigid dosimetry phantom. Copyright © 2011 Elsevier Inc. All rights reserved.

    We report the case of a 60-year-old woman with multiple lymph node metastases after ascending colon cancer who received radiation therapy and then chemotherapy with S-1. She was diagnosed with lymph node metastasis of the para aorta and left upper clavicle 10 months after surgery. We performed radiation therapy for the left upper clavicle (64 Gy)and para aorta (40 Gy). Consequently, we administered S-1(100mg/day)orally. After three months, the upper clavicle lymph nodes had disappeared and the para-aortic lymph nodes reduced. All metastatic lesions disappeared after 10 months. She survived for 32 months after the radiation therapy.

    The aim of the present study was to evaluate whether angiogenic parameters as assessed by trans vaginal color Doppler ultrasound and by enhanced cervix ultrasound may predict prognostic factors of stage I B greater than 4 cm and II cervical cancer treated by radio chemotherapy. A total of 40 patients with histologically proven advanced stage invasive cervical cancer will be evaluated by color Doppler, contrast ultrasound, and MRI before radiotherapy, after the second chemotherapy cycle and prior to surgery. Subjective assessment of the amount of vessels within the tumor (scanty-moderate or abundant) and resistance index (R.I.) will be recorded for Doppler, enhancement and washout period will be studied after injection of SonoVue for contrast ultrasound. All patients will have radical hysterectomy and pelvic lymph node dissection. Comparison with MRI results will be done. The main parameter studied will be persistence of tumor cells in the analysis of the radical hysterectomy. We expected to correlate contrast parameters with persistent disease in order to confirm ultrasound parameters that will be useful to monitor radio chemotherapy and to predict therapeutic answer of such treatment.

    Background Endometrial adenocarcinoma (womb cancer) is a malignant growth of the lining (endometrium) of the womb (uterus). It is distinct from sarcomas (tumours of the uterine muscle). Survival depends the risk of microscopic metastases after surgery. Adjuvant (postoperative) chemotherapy improves survival from some other adenocarcinomas, and there is evidence that endometrial cancer is sensitive to cytotoxic therapy. This systematic review examines the effect of chemotherapy on survival after hysterectomy for endometrial cancer. Objectives To assess efficacy of adjuvant (postoperative) chemotherapy for endometrial cancer. Search methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library 2010, Issue 3), MEDLINE and EMBASE up to August 2010, registers of clinical trials, abstracts of scientific meetings, reference lists of included studies and contacted experts in the field. Selection criteria Randomised controlled trials (RCTs) comparing adjuvant chemotherapy with any other adjuvant treatment or no other treatment. Data collection and analysis We used a random-effects meta-analysis to assess hazard ratios (HR) for overall and progression-free survival and risk ratios (RR) to compare death rates and site of initial relapse. Main results Five RCTs compared no additional treatment with additional chemotherapy after hysterectomy and radiotherapy. Four trials compared platinum based combination chemotherapy directly with radiotherapy. Indiscriminate pooling of survival data from 2197 women shows a significant overall survival advantage from adjuvant chemotherapy (RR (95% CI) = 0.88 (0.79 to 0.99)). Sensitivity analysis focused on trials of modern platinum based chemotherapy regimens and found the relative risk of death to be 0.85 ((0.76 to 0.96); number needed to treat for an additional beneficial outcome (NNT) = 25; absolute risk reduction = 4% (1% to 8%)). The HR for overall survival is 0.74 (0.64 to 0.89), significantly

    Accurately assessing the potential benefit of chemotherapy to cancer patients is an important prerequisite to developing precision medicine in cancer treatment. The previous study has shown that total psoas area (TPA) measured on preoperative cross-section CT image might be a good image marker to predict long-term outcome of pancreatic cancer patients after surgery. However, accurate and automated segmentation of TPA from the CT image is difficult due to the fuzzy boundary or connection of TPA to other muscle areas. In this study, we developed a new interactive computer-aided detection (ICAD) scheme aiming to segment TPA from the abdominal CT images more accurately and assess the feasibility of using this new quantitative image marker to predict the benefit of ovarian cancer patients receiving Bevacizumab-based chemotherapy. ICAD scheme was applied to identify a CT image slice of interest, which is located at the level of L3 (vertebral spines). The cross-sections of the right and left TPA are segmented using a set of adaptively adjusted boundary conditions. TPA is then quantitatively measured. In addition, recent studies have investigated that muscle radiation attenuation which reflects fat deposition in the tissue might be a good image feature for predicting the survival rate of cancer patients. The scheme and TPA measurement task were applied to a large national clinical trial database involving 1,247 ovarian cancer patients. By comparing with manual segmentation results, we found that ICAD scheme could yield higher accuracy and consistency for this task. Using a new ICAD scheme can provide clinical researchers a useful tool to more efficiently and accurately extract TPA as well as muscle radiation attenuation as new image makers, and allow them to investigate the discriminatory power of it to predict progression-free survival and/or overall survival of the cancer patients before and after taking chemotherapy.

    Purpose: A flat-panel detector based mobile isocentric C-arm for cone-beam CT (CBCT) has been developed to allow intraoperative 3D imaging with sub-millimeter spatial resolution and soft-tissue visibility. Image quality and radiation dose were evaluated in spinal surgery, commonly relying on lower-performance image intensifier based mobile C-arms. Scan protocols were developed for task-specific imaging at minimum dose, in-room exposure was evaluated, and integration of the imaging system with a surgical guidance system was demonstrated in preclinical studies of minimally invasive spine surgery. Methods: Radiation dose was assessed as a function of kilovolt (peak) (80-120 kVp) and milliampere second using thoracic and lumbar spine dosimetry phantoms. In-room radiation exposure was measured throughout the operating room for various CBCT scan protocols. Image quality was assessed using tissue-equivalent inserts in chest and abdomen phantoms to evaluate bone and soft-tissue contrast-to-noise ratio as a function of dose, and task-specific protocols (i.e., visualization of bone or soft-tissues) were defined. Results were applied in preclinical studies using a cadaveric torso simulating minimally invasive, transpedicular surgery. Results: Task-specific CBCT protocols identified include: thoracic bone visualization (100 kVp; 60 mAs; 1.8 mGy); lumbar bone visualization (100 kVp; 130 mAs; 3.2 mGy); thoracic soft-tissue visualization (100 kVp; 230 mAs; 4.3 mGy); and lumbar soft-tissue visualization (120 kVp; 460 mAs; 10.6 mGy) - each at (0.3 x 0.3 x 0.9 mm{sup 3}) voxel size. Alternative lower-dose, lower-resolution soft-tissue visualization protocols were identified (100 kVp; 230 mAs; 5.1 mGy) for the lumbar region at (0.3 x 0.3 x 1.5 mm{sup 3}) voxel size. Half-scan orbit of the C-arm (x-ray tube traversing under the table) was dosimetrically advantageous (prepatient attenuation) with a nonuniform dose distribution ({approx}2 x higher at the entrance side than at isocenter

    Liver surgery has been known to cure metastatic colorectal cancer in a small proportion of patients. However, advances in procedural technique and chemotherapy now allow more patients to have safe, potentially curative surgery. Here we review surgery for unresectable colorectal liver metastases using an expert multidisciplinary approach. With multidisciplinary management of patients with effective chemotherapy that can downstage metastases, more patients with previously inoperable disease can benefit from surgery. Portal vein embolization results in hypertrophy of the future liver remnant; on occasions, combining embolization with staged liver resection permits potentially curative surgery for patients previously unable to survive resection. However, increasing use of chemotherapy has raised awareness of potential hepatotoxicity and other deleterious effects of cytotoxic agents. Prolonged prehepatectomy chemotherapy therefore can reduce resectability even using a 2-stage procedure. Suitable timing of surgery for unresectable liver metastases during chemotherapy is critical. Because of advances in chemotherapy, colorectal cancer, like ovarian cancer, can now show survival benefit from maximum surgical debulking. Benefit from such maximum hepatic debulking surgery for metastatic colorectal disease is uncertain, but likely. Surgery in isolation may be approaching technical limits, but is now likely to help more patients because of the success of complementary strategies, particularly newer chemotherapy and targeted therapy. Expert individualized multidisciplinary treatment planning and problem-solving is essential.

    colon cancer is a public health problem worldwide and in Tunisia. The prognosis of patients with unresectable colorectal cancer varies according to the stage. The indication for adjuvant chemotherapy is well established in the colon cancer stage III, while it remains a matter of controversy for stage II. The aim of this work is to identify the epidemiological and anatomoclinical assess therapeutic outcomes in terms of overall survival of patients with high-risk stage II and stage III colon cancer treated with surgery and adjuvant chemotherapy. DS: It's a retrospective study based on 119 patients with colon adenocarcinoma from 1996 to 2010. This patients suffering from colon cancer classified stage II and III having them all radical surgery and adjuvant chemotherapy. The average age of our patients was 53 years. The surgery was performed in an emergency situation in 53 patients (44%). Stages II and III, respectively, were observed in 47% and 53% of cases. Three regimens of chemotherapy were used: protocol FUFOL (50%), followed by FOLFOX (34%) and the protocol LV5FU2 (16%). Overall survival of patients all stages combined was 73.4% at 5 years. Stage III of the TNM classification (p = 0.03) and the number of cycles of chemotherapy colon cancer is improving thanks to recent advances that have enabled the integration of new cytogenetic factors in the therapeutic decision.

    Background and Purpose: Brachytherapy in the treatment of locally advanced cervical cancer has changed substantially because of the introduction of combined intracavitary/interstitial applicators and an adaptive target concept, which is the focus of the prospective, multi-institutional EMBRACE study ( (www.embracestudy.dk)) on image-guided adaptive brachytherapy (IGABT). So far, little has been reported about the development of early to late vaginal morbidity in the frame of IGABT. Therefore, the aim of the present EMBRACE analysis was to evaluate the manifestation pattern of vaginal morbidity during the first 2 years of follow-up. Methods and Materials: In total, 588 patients with a median follow-up time of 15 months and information on vaginal morbidity were included. Morbidity was prospectively assessed at baseline, every 3 months during the first year, and every 6 months in the second year according to the Common Terminology Criteria for Adverse Events, version 3, regarding vaginal stenosis, dryness, mucositis, bleeding, fistula, and other symptoms. Crude incidence rates, actuarial probabilities, and prevalence rates were analyzed. Results: At 2 years, the actuarial probability of severe vaginal morbidity (grade ≥3) was 3.6%. However, mild and moderate vaginal symptoms were still pronounced (grade ≥1, 89%; grade ≥2, 29%), of which the majority developed within 6 months. Stenosis was most frequently observed, followed by vaginal dryness. Vaginal bleeding and mucositis were mainly mild and infrequently reported. Conclusion: Severe vaginal morbidity within the first 2 years after definitive radiation (chemo)therapy including IGABT with intracavitary/interstitial techniques for locally advanced cervical cancer is limited and is significantly less than has been reported from earlier studies. Thus, the new adaptive target concept seems to be a safe treatment with regard to the vagina being an organ at risk. However, mild to moderate vaginal morbidity

Patients and methods: Eighty-two postmenopausal women with estrogen receptor-positive, human epidermal growth-factor receptor 2-negative breast cancer who had completed adjuvant chemotherapy were asked about their preferred route of administration of chemotherapy and the reason. Women also answered questions about their physical and psychological status and quality of life during chemotherapy. Results: Patients who had received oral chemotherapy preferred it more frequently than those who had received intravenous chemotherapy (100% versus 37%, respectively, chi-square =15.5; P<0.001. Patients who preferred the same route of administration of chemotherapy as they had previously received showed a significantly better psychological status during chemotherapy compared with those who preferred a different route. Conclusion: Our study showed that preferences for oral and intravenous chemotherapy strongly depended on the actual prior administration of chemotherapy and patients' own experiences during chemotherapy.

    OBJECTIVE: To investigate the clinical feature,diagnosis,therapies and prognosis of the high intracranial pressure caused by meningitis metastasis, and explore the role of ventriculoperitoneal shunt and intrathecal chemotherapy in the me-ningeal metastases. METHODS! A total of 30 consecutive diagnosed meningitis metastasis patients' whole saliva samples collected from Aug 2009 to Jul 2011 were retrospectively reviewed and analyzed systematically. RESULTS; 30 meningitis metastasis patients had manifested increased intracranial pressure by lumbar puncture tests which were detected greater than 200 mm H2O and appeared headache. Twenty-four cases were positive in cerebro-spinal fluid (CSF) cytology detection. All patients were dealed with peritoneal shunt, and 23 patients received peritoneal shunt and chemotherapy pump implantation. These patients received therapies including surgery, intrathecal chemotherapy, radiotherapy and systemical chemotherapy. The median survival time was 10 months (range 4 weeks to 24 months). CONCLUSIONS;MC is one of the most serious complications of cancer due to the poor prognosis. In this study, MR combined with CSF cytology detection is helpful to the diagnosis of this disease. The ventriculoperitoneal shunt surgery plus chemotherapy pump placement should be considered having satisfactory efficacy for these patients.%目的:总结颅内高压的脑膜转移瘤病例的临床资料,探讨腹腔分流+化疗泵置入术在脑膜转移瘤中的治疗作用.方法:对2009-08-2011-07收治的72例脑膜转移病例中30例颅内压增高的患者进行系统的临床资料回顾性分析.结果:30例患者均有头痛等颅内压增高表现,行腰穿检查均>200 mm H2O.C
