Real-world evaluation of nivolumab in patients with non-nasopharyngeal recurrent or metastatic head and neck cancer: a retrospective multi-center study by the Turkish Oncology Group (TOG).

OBJECTIVES: Head and neck cancers (HNCs) represent a significant global health concern due to high morbidity and mortality rates. Despite therapeutic advances, the prognosis for advanced or recurrent cases remains challenging. Nivolumab obtained approval for recurrent or metastatic HNC based on the Phase III CheckMate 141 trial. This study aimed to evaluate the real-world outcomes of nivolumab in patients with non-nasopharyngeal HNC. DESIGN: In this multicenter retrospective study, we analyzed 124 patients with recurrent or metastatic non-nasopharyngeal HNC who received nivolumab in the second-line setting and beyond. Data were collected from 20 different cancer centers across Turkey. The effectiveness and safety of the treatment and survival outcomes were evaluated. RESULTS: Nivolumab exhibited favorable clinical responses, yielding an objective response rate of 29.9% and a disease control rate of 55.7%. Safety assessments revealed a generally well-tolerated profile, with no instances of treatment discontinuation or mortality due to side effects. Survival analysis disclosed a median overall survival (OS) of 11.8 (95% CI 8.4-15.2) months. Multivariate analysis revealed that ECOG-PS ≥ 1 (HR: 1.64, p = 0.045), laryngeal location (HR: 0.531, p = 0.024), and neutrophil-to-lymphocyte ratio > 3.5 (HR: 1.97, p = 0.007) were independent predictors of OS. CONCLUSIONS: Nivolumab is an effective and safe treatment option for patients with recurrent or metastatic non-nasopharyngeal HNC in real-world settings. Further studies are needed on factors affecting response to treatment and survival outcomes.

Efficacy and tolerability of current treatments for hormone-refractory prostate cancer patients with visceral metastases.

Aim: To assess the efficacy and tolerability of the first-line treatment options for hormone-refractory prostate cancer patients with visceral metastases. Materials & methods: The records of 191 patients diagnosed with hormone-refractory prostate cancer with visceral metastases were analyzed retrospectively. Results: Docetaxel was administered to 61.2% (n = 117), abiraterone to 14.2% (n = 27) and enzalutamide to 9.4% (n = 18) as the first-line treatment. The median survival of the patients receiving docetaxel, abiraterone and enzalutamide as the first-line treatment during the hormone-refractory period was 15 (95% Cl: 12.9-17) months, 6 (95% Cl: 1.8-10.1) months and 11 (95% Cl: 0.9-23.1) months (p = 0.038), respectively. Conclusion: The present study established a statistically significant difference in favor of docetaxel in terms of overall survival and progression-free survival.

Lay abstract The optimal therapeutic option for castration-resistant prostate cancer (CRPC) patients with visceral metastases is unknown. We assessed the efficacy and tolerability of the first-line treatment options for CRPC patients with visceral metastasis. One hundred ninety-one patients diagnosed with CRPC with visceral metastases were included in the study. The present study established a statistically significant difference in favor of docetaxel in terms of overall survival and progression-free survival between first-line docetaxel, abiraterone and enzalutamide treatments in CRPC patients with visceral metastases. For patients who cannot undergo chemotherapy, enzalutamide, among novel androgen pathway inhibitors, may be the most appropriate option, given its numerical, although statistically insignificant, difference in overall survival and its fewer side effects compared with abiraterone.

Prognostic factors in patients with metastatic urothelial carcinoma who have treated with Atezolizumab.

BACKGROUND: Atezolizumab (ATZ) has demonstrated antitumor activity and manageable safety in previous studies of patients with metastatic platinum-resistant urothelial carcinoma. However, the response rate of Atezolizumab was modest. In the current study, we evaluated the pretreatment prognostic factors for overall survival in patients with metastatic urothelial carcinoma who have progressed after first-line chemotherapy in the Expanded-Access Program of Atezolizumab. PATIENTS AND METHODS: In this study, we present a retrospective analysis of 113 patients with urothelial cancer treated with ATZ after progression on first-line chemotherapy. Data of the patients was obtained from patient files and hospital records. Eligible patients included metastatic urothelial carcinoma patients treated with at least one course of ATZ. Univariate analysis was used to identify clinical and laboratory factors that significantly impact OS. Variables were retained for multivariate analysis if they had a statistical relationship with OS (p < 0.1), and then included a final model of p < 0.05. RESULTS: The median follow-up duration was 23.5 months. Of the patients, 98 (86.7%) were male and 13.3% were female. The median age was 65 years of age (37-86). In univariate analysis, primary tumor location in the upper tract, increasing absolute neutrophil count (ANC), increasing absolute lymphocyte count, neutrophil-to-lymphocyte ratio (NLR) > 3, liver metastases, baseline creatinine clearance less (GFR) than 60 ml/min, Eastern Cooperative Oncology Group (ECOG) performance status (1 ≥), and hemoglobin levels below 10 mg/dl were all the significantly associated with OS. Three of the five adverse prognostic factors according to the Bellmunt criteria were independent of short survival: liver metastases HR 3.105; 95% CI 1.673-5.761; p < (0.001), ECOG PS (1 ≥) HR 2.184; 95% CI 1.120-4.256; p = 0.022, and Hemoglobin level below 10 mg/dl HR 2.680; 95% CI 1.558-4.608; p < (0.001). In addition, NLR > 3 hazard ratio [HR] 2.092; 95% CI 1.031-4.243; p = 0.041 and GFR less than 60 ml/min HR 1.829; 95% CI 1.1-3.041; p = 0.02, maintained a significant association with OS in multivariate analysis. CONCLUSIONS: This model confirms the Bellmunt model with the addition of NLR > 3 and GFR less than 60 ml/min and can be associated with clinical trials that use immunotherapy in patients with bladder cancer.

Real-World Efficacy and Safety of First-Line Nivolumab Plus Chemotherapy in Patients with Advanced Gastric, Gastroesophageal Junction, and Esophageal Adenocarcinoma: A Nationwide Observational Turkish Oncology Group (TOG) Study.

Based on the CheckMate 649 trial, nivolumab plus chemotherapy is the recommended first-line treatment for HER2-negative unresectable advanced or metastatic gastric, gastroesophageal junction (GEJ), or esophageal adenocarcinoma. This nationwide, multicenter, retrospective study evaluated the real-world effectiveness of this regimen in Turkish patients and identified subgroups that may experience superior outcomes. Conducted across 16 oncology centers in Turkey, this study retrospectively reviewed the clinical charts of adult patients diagnosed with HER2-negative unresectable advanced or metastatic gastric, GEJ, or esophageal adenocarcinoma from 2016 to 2023. This study included 111 patients (54 women, 57 men) with a median age of 58 years. The median progression-free survival (PFS) and overall survival (OS) were 11.7 months and 18.2 months, respectively, whereas the objective response rate (ORR) was 70.3%. Multivariable analyses revealed that previous curative surgery was a favorable independent prognostic factor for both PFS and OS. Conversely, an Eastern Cooperative Oncology Group performance status of 2 emerged as an adverse independent prognostic factor for OS. The safety profile of nivolumab plus chemotherapy was found to be manageable. Our findings support the use of nivolumab plus chemotherapy for the first-line treatment of Turkish patients with HER2-negative unresectable advanced or metastatic gastric, GEJ, or esophageal adenocarcinoma. Patient selection based on clinical characteristics is crucial for optimizing treatment outcomes.

Efficacy and safety of folfiri plus aflibercept in second-line treatment of metastatic colorectal cancer: Real-life data from Turkish oncology group.

Aims: The addition of aflibercept to the fluorouracil and irinotecan (FOLFIRI) regimen significantly improved clinical outcomes in patients with metastatic colorectal cancer (CRC) previously treated with oxaliplatin. We aimed to investigate the efficacy and safety of second-line FOLFIRI and aflibercept combination in patients with metastatic CRC in real-life experience. Materials and Methods: Four hundred and thirty-three patients who treated with FOLFIRI and aflibercept in the second-line were included in the study. The clinical and pathological features of the patients were recorded retrospectively. Survival (overall and progression-free survival [PFS]), response rates, and safety data were analyzed. Results: The median age was 61. Majority of patients (87.5%) received first-line bevacizumab and 10.1% of patients received anti-epidermal growth factor receptor agents. About 80% of patients had KRAS, 18.6% of patients had NRAS, and 6.4% of patients had BRAF mutations. The median OS was 11.6 months (95% confidence interval [CI], 10.6-12.6) and the median PFS was 6 months (95% CI, 5.5-6.5). About 4.6% of patients had complete response and 30.6% of patients had partial response as best tumor response. Grade 1-2 toxicities were seen in 33.4% of patients, while grade 3-4 toxicities were recorded in 27% of patients. Eight patients (2%) died due to treatment toxicity. Conclusions: Overall and PFS were similar in routine clinical practice compared to phase III pivotal VELOUR trial. However, response rates were found to be higher. It was observed that there were fewer adverse events compared to the VELOUR trial.

Atezolizumab in Patients with Metastatic Urothelial Carcinoma Who Have Progressed After First-line Chemotherapy: Results of Real-life Experiences.

BACKGROUND: Atezolizumab (ATZ) has demonstrated antitumor activity and manageable safety in previous studies in patients with locally advanced or metastatic platinum-resistant urothelial carcinoma. OBJECTIVE: To compare the real-life experience and data of clinical trials on ATZ treatment in metastatic urothelial carcinoma. DESIGN, SETTING, AND PARTICIPANTS: Patients with urothelial cancer treated with ATZ after progression on first-line chemotherapy from an expanded access program were retrospectively studied. Data of patients were obtained from their files and hospital records. Safety was evaluated for patients treated with at least one cycle of ATZ. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary endpoint was objective response rate (ORR). The secondary endpoints are overall survival (OS), progression-free survival (PFS), duration of response, and safety profile of patients. Kaplan-Meier methods were used to calculate median follow-up and estimate PFS and OS. RESULTS AND LIMITATIONS: Data of 115 enrolled patients were analyzed. Most of the patients (92.3%, n = 106) had received chemotherapy regimen only once prior to ATZ. The median follow-up duration was 23.5 mo. The complete response rate, partial response rate, and ORR were 8.7% (n = 10), 20.0% (n = 23), and 28.7% (n = 33), respectively. The median duration of response was 20.4 mo (95% confidence interval [CI], 6.47-28.8). Of the 33 patients who responded to treatment, 60% (n = 20) had an ongoing response at the time of the analysis. PFS and OS with ATZ were 3.8 mo (95% CI, 2.25-5.49) and 9.8 mo (95% CI, 6.7-12.9), respectively. All-cause and any-grade adverse events were observed in 113 (98%) patients. Of the patients, 64% experienced a treatment-related adverse event of any grade and 24 (21.2%) had a grade 3-4 treatment-related adverse event. Limitations of the study included its retrospective design, and determination of treatment response based on clinical notes and local radiographic studies. CONCLUSIONS: In these real-life data, ATZ was effective and well tolerated in patients with metastatic urothelial carcinoma who have progressed with platinum-based first-line chemotherapy. ATZ is an effective and tolerable treatment for patients with locally advanced or metastatic platinum-resistant urothelial carcinoma in our study, similar to previously reported trials. PATIENT SUMMARY: Atezolizumab is effective and well-tolerated in patients with metastatic urothelial cancer who progressed with first-line chemotherapy, consistent with the outcomes of the previous clinical trials in this setting.

Bevacizumab plus irinotecan-based therapy in metastatic colorectal cancer patients previously treated with oxaliplatin-based regimens.

BACKGROUND: Treatment of patients with metastatic colorectal cancer (MCRC) previously exposed to oxaliplatin-based regimen is challenging. Efficacy and toxicity of bevacizumab plus irinotecan-based regimens were assessed in the second-line treatment of MCRC patients. PATIENTS AND METHODS: Forty patients with a median age of 53 years (range, 31-75) were retrospectively evaluated. Patients progressing or relapsing after treatment with oxaliplatin-based regimens were given bevacizumab 5 mg/kg every 2 weeks in combination with irinotecan-based regimens. All patients had previously received oxaliplatin either in the adjuvant setting (n = 8) or for metastatic disease (n = 32). RESULTS: Three patients achieved a complete response (7.5%), 5 partial responses (12.5%) and 14 (35%) stable disease resulting in an overall response rate of 20%. Median progression-free survival was 6 months (95% CI, 4.0-8.0) with a median overall survival of 14 months (95% CI, 10.2-17.8). One-year survival rate was 55.9%. Grade 3-4 toxicities were as follows: neutropenia (n = 15, 37.5%), febrile neutropenia (n = 2, 5%), diarrhea (n = 11, 27.5%), nausea and vomiting (n = 3, 7.5%), gastrointestinal perforation (n = 2, 5%), and thromboembolism (n = 2, 5%). CONCLUSION: Bevacizumab plus irinotecan-based combination chemotherapy is an active and safe treatment option in patients failing oxaliplatin-based therapy.

Synchronous bilateral breast cancer in an aged male patient.

BACKGROUND: Male breast cancer is an uncommon disease. Moreover, synchronous bilateral breast cancer is extremely rare in men. The management is still undefined, although it shows similarities to breast cancers in women. CASE REPORT: We report the case of a 66-year-old male patient who presented with palpable bilateral breast masses. Synchronous bilateral breast cancer was diagnosed with imaging studies and tru-cut biopsy. Histopathological examination revealed bilateral early-stage breast cancer. None of the possible predisposing factors, including hormonal and hereditary history, could be detected. Following bilateral modified radical mastectomy, the patient received adjuvant chemotherapy with tamoxifen. The pertinent literature is reviewed. CONCLUSION: More studies are warranted to better identify possible risk factors for male breast cancers.

Docetaxel combined with oral etoposide as second-line treatment for advanced gastric carcinoma after failure of platinum- and fluoropyrimidine-based regimens.

BACKGROUND: Platinum, antracyline, and fluoropyrimidine combination chemotherapy has been widely used as a first-line treatment for advanced gastric cancer (AGC). In the present study, we determined the efficacy and the safety of docetaxel and oral etoposide as second-line combination chemotherapy after failure of commonly used combination regimens in AGC. METHODS: Patients with histologically proven gastric cancer and measurable metastatic disease received docetaxel 75 mg/m(2) as a 1-h intravenous infusion on day 1, and oral etoposide 50 mg/m(2) once daily on days 1-5, every 3 weeks until disease progression or unacceptable toxicities. RESULTS: Between June 2006 and September 2008, 32 patients, of median age 60 years (range 32-77 years) were included in the study. Overall response rate was 9.4% and 31.3% of patients achieved a stable disease. Median progression-free survival was 3 months (95% CI, 2.5-3.5). Median overall survival was 6 months (95% CI, 3.8-8.2) with 16.9% 1-year survival rate. Grade 3-4 toxicities included neutropenia (28.8%), febrile neutropenia (18.8%), thrombocytopenia (3.1%), nausea and vomiting (15.6%), diarrhea (9.4%), and mucositis (6.2%). CONCLUSION: Docetaxel and oral etoposide combination was moderately effective and safe in appropriately selected AGC patients after failure of platinum- and fluoropyrimidine-based combination regimens.

Cisplatin plus docetaxel combination in the first-line treatment of metastatic non-small cell lung cancer.

AIMS: To evaluate activity and toxicity of cisplatin plus docetaxel combination in the first-line treatment of chemotherapy-naive patients with metastatic non-small cell lung cancer. PATIENTS AND METHODS: Between October 2004 and July 2008, 186 patients with metastatic non-small cell lung cancer treated with first-line cisplatin plus docetaxel were retrospectively evaluated in 7 centers. The chemotherapy schedule consisted of cisplatin, 75 mg/m(2) iv infusion, and docetaxel, 75 mg/m(2) iv infusion on day 1, every 3 weeks. RESULTS: Median age was 56 years (range, 28-75). Eighteen patients (9.7%) were females and 168 (90.3%) were males, with a median ECOG performance status of 1 (range, 0-2). A total of 833 cycles of chemotherapy was administered (median, 4 cycles; range, 1-6). Two patients (1.1%) achieved clinical complete response, 77 patients (41.4%) partial response, and 66 patients (35.5%) stable disease. Median time to disease progression was 6 months (95% CI, 5.54-6.46). Median overall survival was 14.6 months (95% CI, 11.47-17.73). One- and 2-year overall survival was 55.2% and 19.7%, respectively. The most common grade 3-4 hematological toxicities were neutropenia (n = 32, 17.2%) and anemia (n = 4, 2.2%). CONCLUSIONS: The cisplatin plus docetaxel combination was effective and safe in the first-line treatment of patients with metastatic non-small cell lung cancer.

Clinical events in mad honey poisoning: a single centre experience.

The aim was to evaluate the clinical findings of patients who admitted to the hospital with the diagnosis of grayanotoxin/mad honey poisoning. Thirty-three patients were included in this study. Three patients were female (9%) and the others male (91%). Median age of patients was 52 (42-68). The most frequently observed findings were sinus bradycardia (91%), nausea-vomiting (81.8%), and dizziness (78.8%). Average heart rate was 55.35 +/- 6.72 beats/min. Mean systolic and diastolic blood pressures were 77.86 +/- 16.64 mmHg and 46.42 +/- 12.30 mmHg, respectively. Mad honey poisoning is an important problem that is life-threatening in the Black Sea region of Turkey.

UFT plus oral folinic acid with alternating oral and intravenous vinorelbine in patients with metastatic breast cancer previously treated with anthracyclines and taxanes.

BACKGROUND: We retrospectively evaluated the activity and toxicity of uracil/tegafur (UFT) plus oral folinic acid in combination with vinorelbine (alternating intravenous (IV) on day 1 and oral on day 8) in patients with metastatic breast cancer. PATIENTS AND METHODS: Treatment consisted of IV vinorelbine 25 mg/m(2) on day 1 and 60 mg/m(2) orally on day 8, and oral UFT 300 mg/m(2) plus leucovorin 60 mg/m(2) on days 1-14 with 21 days interval. All patients were refractory to anthracyclines and taxanes. RESULTS: Partial response (PR) was observed in 3 (9.7%) and stable disease (SD) was observed in 13 (41.9%) patients. Total clinical benefit (PR + SD) of the combination was 51.6%. The median response duration was 3 (range 1-11.8) months. Median overall survival was 9.8 months (95% confidence interval (CI): 7.5-12.1), and median time to progression was 3.4 months (95% CI: 2.3-4.5). The most common toxicities were hematologic, including 4 (12.9%) cases of grade 3 neutropenia and 4 (12.9%) cases of grade 4 neutropenia. Grade 3 diarrhea was reported in 2 (3.2%) patients. 3 (9.7%) patients had hand-foot syndrome. Febrile neutropenia was observed in 1 patient. CONCLUSIONS: Although the combination is safe and convenient in clinical practice, it has only moderate activity in metastatic breast cancer patients.

Opportunistic cytomegalovirus infection in a patient receiving temozolomide for treatment of malignant glioma.

Treatment of malignant gliomas has changed substantially over the last few years. An oral alkylating agent, temozolomide, has become the standard agent for glioma management. Although it is generally well tolerated, it can cause lymphopenia and may lead to opportunistic infections. We report on a patient with malignant glioma who developed opportunistic cytomegalovirus (CMV) pneumonia following the termination of temozolomide therapy. The patient was admitted with acute dyspnea, fever and hypoxia, and she was diagnosed with CMV pneumonitis using a PCR-based CMV-DNA analysis. After treatment with ganciclovir, she recovered dramatically. To our knowledge, although there have been reported cases of Pneumocystis carinii infection associated with temozolomide therapy, there has only been one other case of CMV infection. We also review this report.

Coexistence of gastrointestinal stromal tumor (GIST) of the rectum and adenocarcinoma of the prostate in a patient with familial GIST.

BACKGROUND: Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors of the gastrointestinal system. The rectum is a rare location for GIST. Prostate adenocarcinoma is the most common malignancy in geriatric men. Rarely, rectal GIST mimics prostate pathologies. CASE REPORT: We describe a 58-year-old male patient who was admitted with signs and symptoms of prostatism. A presumptive diagnosis of primary prostate sarcoma was made based on imaging studies and a trucut biopsy. Removal of the mass compressing both the prostate and the rectum revealed the final diagnosis of synchronous prostate adenocarcinoma and high-grade GIST originating from the rectum. The patient also had a family history of GIST. CONCLUSION: According to our knowledge, there are 5 more reported cases of rectal GIST, which were misdiagnosed as prostate malignancy. Rectal GIST may simulate prostate carcinoma clinically, and should always be kept in mind in the differential diagnosis of prostate pathologies.

Temozolomide in newly diagnosed malignant gliomas: administered concomitantly with radiotherapy, and thereafter as consolidation treatment.

BACKGROUND: Surgical resection followed by radiotherapy used to be the standard treatment in malignant gliomas. Recently, temozolomide has become a cornerstone in the treatment of these patients. We evaluated retrospectively the efficacy and the toxicity of temozolomide which was administered concomitantly with radiotherapy, and thereafter as consolidation treatment. PATIENTS AND METHODS: Medical records of 64 patients with malignant glioma were reviewed. Postoperatively, temozolomide was given at a dose of 75 mg/m(2)/day concomitantly with cranial radiotherapy. After 4 weeks of rest, patients were treated with temozolomide 200 mg/m(2) on days 1-5 every 28 days for 6 cycles. RESULTS: 62 patients were evaluable for response and toxicity. Objective response rate was 38.7% including 7 (11.3%) complete responses, and 17 (27.4%) partial responses. Median progression-free survival, and overall survival have not yet been reached in the grade III astrocytoma group at a median follow-up of 19 months. In the glioblastoma multiforme group, median progression-free survival, and median overall survival were 10 and 19 months, respectively. 2-year survival rates were 80% and 19% for the grade III astrocytoma, and for the glioblastoma multiforme groups, respectively. Toxicity was mild to moderate with rare grade 4 toxicities. CONCLUSION: Our data suggest that temozolomide is an active regimen for malignant gliomas. It was more effective in younger patients with better performance status.

Single agent gemcitabine in the second-line treatment of advanced non-small cell lung cancer after treatment with taxane + platinum regimens.

In this study, we investigated the activity of single agent gemcitabine in the second-line setting of non-small cell lung cancer (NSCLC). File records of 21 patients treated with single agent gemcitabine in advanced NSCLC who received one prior chemotherapy including a taxane and platinum combination were retrospectively evaluated. Treatment consisted of IV gemcitabine 1,250 mg/m2 on days 1 and 8, followed by a 1-week rest repeated every 3 weeks. A partial response was achieved in four (19%) patients. The median response duration was 16 (range, 12-32) weeks. Six (29%) patients had a SD more than 3 months. The median time to progression was 16 (range, 8-32) weeks. No complete response was observed. Median overall survival was 36 weeks for second-line gemcitabine in all patients (95%: CI 5-13 months). Hematological toxicity (all grades) was reported by 9 (42.9%) patients. One (4.75%) patient experienced grade 3/4 neutropenia. Grade 3/4 nausea and vomiting and mucositis were reported in one (4.75%) patient. In conclusion, this study shows that single agent gemcitabine is active and well tolerated as a second-line therapy for advanced NSCLC.

Carboplatin and oral cyclophosphamide combination after temozolomide failure in malignant gliomas.

BACKGROUND: Temozolomide is a novel cytotoxic agent for malignant gliomas. However, treatment failure occurs approximately in half of patients, and the optimal regimen in this setting has yet to be defined. In the present study, we assessed retrospectively the efficacy and toxicity of the combination of carboplatin and oral cyclophosphamide in temozolomide-resistant patients. METHODS: We evaluated the medical records of 30 patients with malignant gliomas. After failure of temozolomide therapy, patients were treated with a combination of carboplatin and oral cyclophosphamide. Treatment consisted of intravenous carboplatin AUC 6 (based on the Calvert Formula) on day 1 and oral cyclophosphamide 75 mg/m2 daily on days 1 to 14, followed by 14 days of rest, with the treatment repeated every 4 weeks. RESULTS: All patients were evaluated for response and toxicity. The objective response rate was 30%, including 9 partial responses. Median time to disease progression and median overall survival was 7 months and 8 months, respectively. Clinically responsive patients had statistically significant longer progression-free survival and overall survival than unresponsive patients. Hematological side effects were commonly observed toxicities, with neutropenia the most frequent. CONCLUSIONS: Our data suggest that carboplatin and oral cyclophosphamide therapy is a convenient regimen after failure of temozolomide therapy in patients with malignant gliomas because of its activity, feasibility and tolerability. Further prospective studies are needed in this setting.

Acute erythema and edematous skin reaction and ectropion following docetaxel in a patient with non-small cell lung cancer.

Docetaxel can cause skin reactions such as hypersensitivity, edema, and erythrodysesthesia syndrome as well as side effects involving the skin, including alopecia, nail onycholysis, nail pigmentation, photosensitivity, scleroderma, and paresthesia. In this case report, a patient was admitted to the hospital with widespread erythematous and edematous eruption in the head, neck, trunk, and lower and upper extremities, erythema around the eyes, and drooping of the lower eyelids that developed about 2 hours after receiving chemotherapy consisting of docetaxel. Use of the Naranjo Adverse Drug Reaction Probability Scale--a method for estimating the probability of adverse drug reactions--indicated a probable relationship between the skin reaction and docetaxel therapy in this patient. Docetaxel-associated skin reactions that are so extensive and severe as to lead to eye madarosis and ectropion are reported rarely in the literature.

Solitary iris metastasis from breast cancer with dramatic course: case report.

Intraocular metastases are the most common malignancy of eye. Breast cancer is more frequently a cause of intraocular metastases. As a first metastatic site, iris and ciliary body are relatively rare. We report a case of a 52-year-old woman, operated for breast cancer 16 months ago and diagnosed multiple brain metastases 1 month ago. After first course of chemotherapy she was admitted to hospital with the complaints of eye pain and she recognized a solid mass on iris. Iris and ciliary metastases were diagnosed by ophthalmological examination. Because of the patient's poor general condition, diagnostic aspiration from eye metastasis could not be performed. Intramedullary mass was determined 1 month later and she died 2 months later. Ciliary body and iris metastases of breast cancer must be considered as a manifestation of aggressive clinical course and poor prognosis. The eye metastases of breast cancer are a part of systemic illness and must be treated by systemic chemotherapy.

Capecitabine plus oxaliplatin (xelox) in the treatment of chemotherapy-naive patients with metastatic colorectal cancer.

BACKGROUND: Capecitabine and oxaliplatin are both synergistically active against metastatic colorectal cancer (MCRC). We evaluated our experience at two centers with capecitabine and oxaliplatin combination (XELOX) in previously untreated patients with MCRC. PATIENTS AND METHODS: We reviewed medical records of 85 previously untreated patients with MCRC who received first-line XELOX regimen. Oxaliplatin was given at a dose of 130 mg/m2 on day 1 in combination with capecitabine 1500 mg/m2/day on days 1-14 every 3 weeks. RESULTS: Seventy-six of 85 patients were evaluated for response and toxicity. Patients with a follow up of less than 6 months were excluded from the study. Objective response rate was 46% including 8 complete responses (10.5%) and 27 partial responses (35.5%). Additionally, 20 patients (26.3%) had disease stabilization at least 3 months after the treatment. The patients were followed for a median 12.5 months (range 2-32). Median time to disease progression (TTP) was 11 months (range 2-27 months). Median overall survival (OS) time has not yet been reached. One-year survival rate was 66%. Toxicity was modest with infrequent grade 3-4 adverse effects. CONCLUSION: XELOX is an active regimen against MCRC in the first-line setting with favorable toxicity profile. Our results appear to be comparable, if not superior, to the results of other reports of first-line XELOX therapy in respect to objective response rates, survival data, and safety profile. Convenience with oral administration of every 3-week schedule makes XELOX regimen a compelling therapeutic option in the treatment of first-line MCRC.
