Evaluation of EGFR inhibitor-mediated acneiform skin toxicity within the double-blind randomized EVITA trial: A thorough gender-specific analysis using the WoMo score.

Acne-like skin reactions frequently occur in patients undergoing treatment with drugs inhibiting the epidermal growth factor receptor. Recently, the effects of vitamin K1 containing cream (Reconval K1) as prophylactic skin treatment in addition to doxycycline were explored in a double-blind randomized phase II trial (EVITA) in patients with metastatic colorectal cancer receiving cetuximab. EVITA demonstrated a trend towards less severe skin rash in Reconval K1-treated patients using the tripartite WoMo skin reaction grading score as a thorough tool for quantification of drug related skin reactions. This gender-specific analysis of the EVITA trial evaluated the application of the WoMo score for assessment of epidermal growth factor receptor (EGFR)-related skin toxicities according to treatment arm and gender. To show the robustness of results parametric and non-parametric statistical analyses were conducted. All three parts of the WoMo score independently demonstrated the superiority of the treatment arm (Reconval K1) regarding a significant reduction in acneiform skin reactions in women. Men did not benefit from Reconval K1 cream at any time point in none of the WoMo score analyses. The treatment effect in women was confirmed by the use of skin rash categories based on the final WoMo overall score and mixed effect longitudinal multiple linear regression analysis. The WoMo score represents a sensitive tool for studies exploiting treatments against EGFR mediated acne-like skin rash. Part C of the WoMo score seems to be sufficient for quantification of drug related skin toxicities in further studies. Standard WoMo skin reaction score values for future studies are provided.

AIO LQ-0110: a randomized phase II trial comparing oral doxycycline versus local administration of erythromycin as preemptive treatment strategies of panitumumab-mediated skin toxicity in patients with metastatic colorectal cancer.

BACKGROUND: Dermatologic toxicities, especially akne-like skin rash, are the most common side-effects associated with anti-epidermal growth factor receptor (EGFR) therapy. Preemptive treatment with oral tetracyclines is recommended as a standard. Topical prophylactic options have thus far not been compared to tetracyclines. In the current study, we sought to establish an alternative topical treatment. PATIENTS AND METHODS: In this multicentre, randomized, open-label phase II study patients with (K)Ras-wildtype colorectal cancer receiving panitumumab were randomized (1:1) to receive either doxycycline 100 mg b.i.d. (standard arm) or erythromycin ointment 2% followed by doxycycline in case of insufficient activity. The primary endpoint was the percentage of patients developing no skin toxicity ≥ grade 2 at any time during the first 8 weeks of panitumumab treatment. Skin toxicity was assessed using the NCI CTCAE v 4.0. Secondary endpoints comprised the assessment of skin toxicity using a more thorough grading system (WoMo score), evaluation of skin-related (DLQI) and global quality of life (EORTC QLQ C30). RESULTS: In total, 88 patients were included in this trial. 69% of the patients in the erythromycin arm suffered from skin toxicity of grade ≥ 2 versus 63% in the standard arm (P = n.s.). However, as per WoMo score significantly more patients in the erythromycin arm developed moderate or severe skin toxicity at earlier time points. Skin related and overall quality of life was comparable between both arms. CONCLUSIONS: Based on this data erythromycin cannot be regarded as an alternative to doxycycline as prevention of EGFR-related skin toxicity.

Panitumumab in Combination With Preoperative Radiation Therapy in Patients With Locally Advanced RAS Wild-type Rectal Cancer: Results of the Multicenter Explorative Single-Arm Phase 2 Study NEORIT.

PURPOSE: Studies investigating combinations of anti-epidermal growth factor receptor monoclonal antibodies such as panitumumab or cetuximab with standard chemoradiation therapy protocols in rectal cancer have yielded disappointing results. Because of the supposed negative interaction of epidermal growth factor receptor inhibition and chemoradiation therapy, we conducted a phase 2 study using single-agent panitumumab in combination with radiation therapy in patients with RAS wild-type locally advanced rectal cancer. METHODS AND MATERIALS: Patients with RAS wild-type locally advanced (clinical stage II or III) rectal cancer localized 0 to 12 cm from the anus were eligible for study participation. The primary objective of the study was to determine pathologic complete response (pCR). Secondary objectives comprised assessing the safety, surgical morbidity, clinical response, tumor downstaging, and tumor regression grading according to Dworak. RESULTS: A total of 54 patients with a median age of 58 years were treated. In 3.7% of patients, pCR was achieved. Downstaging of the primary tumor or lymph nodes was seen in 65% of patients. No grade ≥2 hematologic toxicity was seen. The most common grade ≥3 nonhematologic toxicities were skin toxicity (24%) and diarrhea (10%). CONCLUSIONS: Panitumumab in combination with radiation therapy as neoadjuvant treatment for locally advanced rectal cancer showed a favorable toxicity profile but failed to meet the predefined pCR rate to justify further clinical trials.

Baseline and On-Treatment Markers Determining Prognosis of First-Line Chemotherapy in Combination with Bevacizumab in Patients with Metastatic Colorectal Cancer.

BACKGROUND: In metastatic colorectal cancer, no upfront or on-treatment markers are available to determine the prognosis or efficacy for chemotherapy in combination with bevacizumab. PATIENTS AND METHODS: The current analysis was performed to evaluate the prognostic value of disease and patient characteristics (age, number of metastatic sites, stage of primary tumor, performance status, carcinoembryonic antigen (CEA)) and on-treatment changes of CEA (response after 8-12 weeks of treatment and specific patterns of CEA kinetics) in patients from an observational cohort study of chemotherapy with bevacizumab. RESULTS: Baseline factors were available from 1,438 patients. Patients with baseline CEA levels > 20 ng/ml, more than 1 metastatic site, and age > 75 years showed significantly lower progression-free (PFS) and overall survival in multivariate analysis. A CEA response of > 30% during treatment was associated with increased PFS. In addition, the pattern of CEA kinetics predicts survival and response to treatment. CONCLUSION: In summary, baseline CEA, number of metastatic sites, and age are strong independent prognostic factors for survival. By monitoring CEA, clear patterns with distinct prognostic value can be determined. CEA kinetics and/or response after 8-12 weeks might be a useful and simple tool to stratify the post-induction treatment approach based on individual prognosis in the future.

Outcome of Colorectal Cancer Patients Treated with Combination Bevacizumab Therapy: A Pooled Retrospective Analysis of Three European Cohorts from the Angiopredict Initiative.

BACKGROUND/AIMS: This study is aimed at analyzing the survival rates and prognostic factors of stage IV colorectal cancer patients from 3 European cohorts undergoing combination chemotherapy with bevacizumab. METHODS: Progression free-survival (PFS) and overall survival (OS) were analyzed in 172 patients using the Kaplan-Meier method and uni- and multivariable Cox proportional hazards regression models. RESULTS: The median PFS was 9.7 and the median OS 27.4 months. Patients treated at centers in Germany (n = 97), Ireland (n = 32), and The Netherlands (n = 43) showed a median PFS of 9.9, 9.2, and 9.7 months, OS of 34.0, 20.5, and 25.1 months, respectively. Patients >65 years had a significantly shorter PFS (9.5 vs. 9.8 months) but not OS (27.4 vs. 27.5 months) than younger patients. High tumor grade (G3/4) was associated with a shorter PFS, T4 classification with both shorter PFS and OS. Fluoropyrimidine (FP) chemotherapy backbones (doublets and single) had comparable outcomes, while patients not receiving FP backbones had a shorter PFS. In multivariable analysis, age and non-FP backbone were associated with inferior PFS, T4 classification and therapy line >2nd were significantly associated with poor PFS and OS. CONCLUSION: The observed survival rates confirm previous studies and demonstrate reproducible benefits of combination bevacizumab regimens. Classification T4, non-FP chemotherapy backbone, and age >65 were associated with inferior outcome.

Prognostic Impact of mRNA Expression Levels of HER1-4 (ERBB1-4) in Patients with Locally Advanced Rectal Cancer.

Background. No predictive or prognostic biomarker is available for patients with locally advanced rectal cancer (LARC) undergoing perioperative chemoradiotherapy (CRT). Members of the human epidermal growth factor receptor (HER) family of receptor tyrosine kinases EGFR (HER1, ERBB1), HER2 (ERBB2), HER3 (ERBB3), and HER4 (ERBB4) are therapeutic targets in several cancers. The analysis was performed to assess expression levels and study the potential prognostic impact for disease-free and overall survival in patients with LARC. Patients and Methods. ERBB1-4 mRNA expression and tumor proliferation using Ki-67 (MKI67) mRNA were evaluated using RT-quantitative PCR in paraffin-embedded tumor samples from 86 patients (median age: 63) treated with capecitabine or 5-fluorouracil-based CRT within a phase 3 clinical trial. Results. A positive correlation of HER4 and HER2, HER3 and HER2, and HER4 and HER3 with each other was observed. Patients with high mRNA expression of ERBB1 (EGFR, HER1) had significantly increased risk for recurrence and death. Patients with high mRNA expression of MKI67 had reduced risk for relapse. Conclusion. This analysis suggests a prognostic impact of both ERBB1 and MKi67 mRNA expression in LARC patients treated with capecitabine or fluorouracil-based chemoradiotherapy.

Use of Complementary and Alternative Medicine in Cancer Patients: A Prospective Questionnaire-Based Study in an Oncological Outpatient Clinic.

BACKGROUND: A questionnaire-based prospective study was conducted to evaluate the current use of complementary and alternative medicine (CAM) in a hemato-oncological outpatient clinic. METHODS: A multiple-choice questionnaire was designed to assess the use of CAM in a hemato-oncological outpatient clinic. It consisted of questions on sociodemographic and general patient data, and of different kind of questions concerning the use of CAM, including disclosure rates to oncologists and general physicians. The data was analyzed with SAS and a p-value < 0.05 was considered as statistically significant. RESULTS: 46 out of 251 patients (18%) indicated to use CAM. 62 out of all patients (25%) discussed the topic with their general physician or oncologist. Praying or nutritional supplements were the most often used type of CAM. 95 of all participating patients found that the use of CAM could be helpful. CONCLUSIONS: The findings of our monocentric study in an outpatient setting do not support the relatively high percentage of CAM users described in the current literature. Nevertheless, CAM needs to be defined more clearly, in order to increase the patients' awareness of CAM.

Integrating patient reported measures as predictive parameters into decisionmaking about palliative chemotherapy: a pilot study.

BACKGROUND: Systemic treatment has proven to improve physical symptoms in patients with advanced cancer. Relationship between quality of life (QoL) or symptom burden (SYB) and treatment efficacy (tumour response and survival) is poorly described. Therefore, we evaluated the predictive value of pretreatment QoL and SYB on treatment outcomes. METHODS: Eligible patients had metastatic gastrointestinal cancers and were about to receive 1st/2nd line palliative chemotherapy. 47 patients were consecutively enrolled. QoL and SYB were assessed by EORTC QLQ-C30 and MSKCC MSAS questionnaires before treatment and after first response evaluation after 8-12 weeks. Logistic regression analysis of QoL and SYB for prediction of objective treatment efficacy was performed. Patients were categorized according to response rate (RR) based on RECIST1.1 and progression free survival (PFS). PFS was categorized by a ratio (individual PFS/expected PFS) in above median (ratio ≥ 1) or below median PFS (ratio < 1). QoL and SYB were analysed for RR groups (partial response, stable or progressive disease) and PFS ratio (PFSR). RESULTS: Objective response to chemotherapy and increase in PFS were associated with better pretreatment QoL and less SYB. Patients with future objective treatment efficacy (PFSR ≥ 1) evidenced clinically relevant better role/emotional/cognitive/social functioning and less fatigue and appetite loss at baseline in comparison to PFSR < 1 (>10 points difference). Lowest scores in all functioning scales at treatment start were seen in patients with future PFSR < 1. Global health status (EORTC), PSYCH subscale and global distress index (MSAS) predicted PFSR, even if adjusted for gender, age, cancer type, ECOG and line of treatment (p < 0.05). Interestingly, improved QoL and SYB (subjective benefit) were noted even in patients with worse pretreatment status and no objective tumour response. CONCLUSION: Future non-responders seem to show distinct QoL patterns before chemotherapy. This may facilitate early detection of patients deriving less or even no benefit from treatment regarding prolongation of survival. Even in patients with primarily progressive disease QoL and SYB may improve during treatment. Integration of QoL and SYB assessment into decision-making about palliative chemotherapy seem to be an important approach to improve patient outcome and should be further evaluated.

Does physical activity improve quality of life in cancer patients undergoing chemotherapy?

BACKGROUND: Improved cancer treatments have resulted in prolonged survival. Nevertheless, tumor symptoms and side effects still compromise physical activity and quality of life (QoL). PATIENTS AND METHODS: We conducted an anonymous survey among cancer patients undergoing chemotherapy using standardized questionnaires: the 'Freiburger Fragebogen zur körperlichen Aktivität' (Freiburg Questionnaire on Physical Activity) and European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30. Two main questions were addressed: were there differences (1) in physical activity and QoL between patients who do not believe that sport could improve their QoL and those who believe it could (group A vs. B); and (2) in QoL between patients with a total activity (TA) < 18 metabolic equivalent of task (MET) h/week and those with a TA of ≥ 18 MET h/week (group C vs. D)? RESULTS: 276 of 400 questionnaires were completed. Groups A and B were balanced in terms of baseline characteristics. Group A suffered significantly more from fatigue and pain; group B reported higher levels of global health status (GHS) and TA. Groups C and D differed in gender distribution, age, and educational background. Group D had significantly higher levels of GHS, group C suffered more from fatigue, pain, and appetite loss. CONCLUSION: Physical activity correlates with a better QoL of cancer patients undergoing chemotherapy.

Mitomycin C and capecitabine in pretreated patients with metastatic gastric cancer: a multicenter phase II study.

PURPOSE: We conducted a multicenter phase II study to assess the toxicity and efficacy of a combination of mitomycin C (MMC) and capecitabine in pretreated patients with metastatic or locally advanced gastric cancer. METHODS: Thirty-nine patients (77 % male) between 33 and 78 years (median 66) with pretreated locally advanced or metastatic esophagogastric adenocarcinoma and eastern cooperative oncology group performance status of ≤2, measurable lesions, and adequate organ functions were recruited into the study. Eight patients (21 %) had received more than one prior chemotherapy regimen. Treatment consisted of three-weekly MMC 10 mg/m(2) day 1 and capecitabine 2,000 mg/m(2) (day 1-14; repeated day 22). RESULTS: A median of three cycles of therapy was administered. Grade 3 toxicity occurred in 20 patients (54 %). Main grade 3 adverse events were thrombocytopenia (11 %, n = 4), fatigue (8 %, n = 3), and neuropathy (8 %, n = 3). Two events of grade 4 toxicity were reported (5 %) (dyspnea and elevation of alkaline phosphatase due to bone metastases). Partial remission was noticed in 10.3 % (n = 4), stable disease in 33.3 % (n = 13) adding to a tumor control rate of 43.6 %. The median progression-free and overall survival were 2.8 and 5.6 months, respectively. CONCLUSION: The combination of MMC and capecitabine exhibited a favorable tolerability profile in pretreated patients with gastric cancer. The disease control rate compares adequately with that of other phase II and phase III trials for second-line therapy in gastric cancer. This regimen may be considered as an alternative second-line treatment, especially for patients not suitable for or pretreated with taxanes and/or irinotecan.

Quality of life of older adult patients receiving docetaxel-based chemotherapy triplets for esophagogastric adenocarcinoma: a randomized study of the Arbeitsgemeinschaft Internistische Onkologie (AIO).

BACKGROUND: Treatment of patients with advanced or metastatic esophagogastric adenocarcinoma should not only prolong life but also provide relief of symptoms and improve quality of life (QOL). Esophagogastric adenocarcinoma mainly occurs in elderly patients, but they are underrepresented in most clinical trials and often do not receive effective combination chemotherapy, most probably for fear of intolerance. Using validated instruments, we prospectively assessed QOL within the randomized FLOT65+ phase II trial. METHODS: Within the FLOT65+ trial, a total of 143 patients aged ≥65 years were randomly allocated to receive biweekly oxaliplatin plus 5-fluorouracil (5-FU) continuous infusion and folinic acid (FLO) or the same regimen in combination with docetaxel 50 mg/m(2) (FLOT). The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30) and the gastric module STO22 were administered every 8 weeks until progression. Time to definitive deterioration of QOL parameters was analyzed and compared within the treatment arms. RESULTS: The median age of patients was 70 years. Patients receiving FLOT exhibited higher response rates and had improved disease-free and progression-free survival (PFS). The proportions of patients with evaluable baseline EORTC QLQ-C30 and STO22 questionnaires were balanced (83 % in FLOT and 89 % in FLO). Considering evaluable patients with assessable questionnaires (n = 123), neither functioning nor symptom parameters differed significantly in favor of one of the two treatment groups. Particularly, there was no significant difference regarding time to definitive deterioration of global health status/quality of life from baseline (primary endpoint). Notably, patients receiving FLO or FLOT as palliative treatment (n = 98) achieved comparable QOL results. CONCLUSIONS: Although toxicity was higher in patients receiving FLOT, no negative impact of the addition of docetaxel on QOL parameters could be demonstrated. Thus, elderly patients in need of intensified chemotherapy may receive FLOT without compromising patient-reported outcome parameters.

Cancer patients and advance directives: a survey of patients in a hematology and oncology outpatient clinic.

BACKGROUND: In 2009, Germany enacted a new law supporting advance directives that led to heated discussions in the media and the public. 3 years after the law passed, we surveyed patients with malignant diseases with regards to their views on advance directives. PATIENTS AND METHODS: Between September 2011 and July 2012 an anonymous survey on advance directives was conducted among 617 patients at the hematology and oncology outpatient department of the University Hospital Mannheim, using a standardized questionnaire developed for this investigation. RESULTS: Of the 503 patients who returned the questionnaire, 31% (n = 157) indicated having an advance directive. Of these 157, 54% (n = 85) completed the advance directive after 2009. 56% (282 out of 503) desired more information on advance directives. Of these, 71% (201 out of 282) wanted their general physician and 45% (128 out of 282) their specialist, to provide more information about this issue. Of the 339 patients without an advance directive, 47% (n = 158) stated that they had 'not worried about that yet'. CONCLUSION: Although the percentage of patients with advance directives has increased since the legislative amendment, more information is still required by patients. It is recommended that physicians should discuss advance directives more frequently with their patients.

Efficacy and safety of capecitabine in combination with docetaxel and mitomycin C in patients with pre-treated pancreatic, gallbladder, and bile duct carcinoma.

PURPOSE: Preclinical data indicate the improvement of the antitumor activity of capecitabine by mitomycin C and docetaxel through upregulation of thymidine phosphorylase activity. Therefore, we have established a combination regimen of these drugs (DocMitoCape), which demonstrated preliminary activity especially in bile duct and pancreatic carcinoma. METHODS: Here we report the safety and efficacy of the DocMitoCape regimen in pre-treated patients with gallbladder, bile duct, or pancreatic carcinoma. Treatment consisted of capecitabine (2,000 mg/m(2) days 1-14) in combination with docetaxel (40 mg/m(2) day 1) and mitomycin C (4 mg/m(2) day 1). Cycles were repeated on day 22. Toxicity was graded according to NCI-CTC criteria, and the antitumor activity was assessed by RECIST criteria. RESULTS: Twenty-eight pre-treated patients with a median age of 59 suffering from pancreatic, gallbladder, intra- (IHCCC) or extrahepatic (EHCCC) bile duct carcinoma were included. Eleven patients had received ≥2 lines of prior chemotherapy. A total of 183 and a median of six cycles were administered (range 1-21). The mean dose intensity was as follows (cycles 1-2/3-4; %): capecitabine 97/92, docetaxel 100/100, mitomycin C 99/100. Main adverse events grades 2/3/4 were (n): leukocytopenia 3/2/2, anemia 13/4/0, thrombocytopenia 3/1/0, nausea/vomiting 2/1/0, diarrhea 5/1/0, hand-foot-skin reaction 7/0/0. Six patients achieved partial and seven patients minor remissions, while six patients had stable disease adding to a tumor control rate of 68%. Median progression-free and overall survival was 4.5 (range 1.0-44.9) and 6.8 months (range 1.5-44.9), respectively, calculated from the start of treatment. CONCLUSION: In all, the DocMitoCape regimen exhibited a favorable safety profile and a high rate of tumor stabilizations in patients with pre-treated gallbladder, bile duct and pancreatic carcinoma. It might be considered after failure of standard regimens in these types of cancer.

Treatment of epidermal growth factor receptor antagonist-induced skin rash: results of a survey among German oncologists.

BACKGROUND: Skin toxicities are frequent in patients receiving epidermal growth factor receptor (EGFR) antagonists. Grading and management of these skin reactions are poorly standardized. MATERIALS AND METHODS: We conducted a survey among German oncologists using a 7-item questionnaire distributed by e-mail via the working groups Internistische Onkologie (AIO) and Dermatologische Onkologie (ADO). The oncologists were provided with pictures and history of a patient with an acneiform rash and were asked to provide information on grading and treatment strategies. RESULTS: 106 medical oncologists and 43 dermatooncologists responded to the survey. The scoring of the skin rash was indicated as follows (National Cancer Institute common toxicity criteria (NCICTC) grades 1/2/3;%): 10/59/31. 22% of the polled medical oncologists use preemptive treatment of skin rash. In the presented case, 91% chose local treatment with mainly hydrocortisone or antibiotic cream, and 64% chose systemic treatment with an antibiotic or isotretinoin. Only 9% of the medical oncologists would have referred the patient to a dermatologist. Dermatooncologists used more local antibiotics (p = 0.006) and rather less local steroids (p = 0.199). With regard to systemic treatment, dermatooncologists more often used isotretinoin (p = 0.002). In addition, dermatooncologists less often delayed cetuximab treatment because of skin toxicity (p = 0.009). CONCLUSIONS: The results of the present analysis illustrate that grading and treatment of EGFR antagonistinduced skin toxicities are very heterogeneous. Clearly, more randomized trials and a simple and reliable grading system are warranted.

Cetuximab-based treatment of metastatic anal cancer: correlation of response with KRAS mutational status.

BACKGROUND: No standard chemotherapy regimen can be defined for patients with metastatic squamous cell carcinoma of the anus due to the low incidence of this disease and the high cure rate of localized tumors. Anal cancers universally express the epidermal growth factor receptor (EGFR) and KRAS mutations have not been reported in anal cancer thus far. METHODS: We report on 7 patients with metastatic anal cancer treated with cetuximab - a chimeric antibody against EGFR - on a compassionate use basis along with the results of KRAS mutational analysis. RESULTS: Marked tumor shrinkage was noted in several patients using cetuximab monotherapy or cetuximab/irinotecan combination as first or subsequent treatment line (usually after failure of cisplatin-based regimens). Two out of seven patients harbored KRAS mutations. Both patients had progressive disease receiving cetuximab, while the remaining 5 patients had either a partial remission (n = 3), a minor remission (n = 1) or no change lasting > or =6 months after previous rapid tumor progression. CONCLUSION: Cetuximab-based treatment appears to be a valuable treatment option for patients with metastatic KRAS wild-type anal cancer after failure of or as an alternative to cisplatin/5-fluorouracil-based therapy.

The soluble transferrin receptor (TfR)-F-Index is not applicable as a test for iron status in patients with chronic lymphocytic leukemia.

BACKGROUND: The soluble transferrin receptor (sTfR) is established as a test for iron deficiency (ID). In chronic lymphocytic leukemia (CLL), sTfR is not reliable for screening for ID as the latter is strongly dependent on tumor burden. METHODS: We investigated whether the influence of the tumor load can be excluded or minimized using the sTfR/log ferritin ratio (TfR-F-Index) and the C-reactive protein (CRP)-adjusted TfR-F-Index in 87 patients with CLL. sTfR was measured nephelometrically (normal: 0.81-1.75 mg/L). A cut-off value of 1.5 for the TfR-F-Index and 0.8 for the CRP-adjusted TfR-F-Index, in patients with a CRP >5 mg/L, was used. RESULTS: All Binet A patients had normal sTfR values (1.34+/-0.2 mg/L), TfR-F-Index (0.67+/-0.2) and a CRP-adjusted TfR-F-Index. In Binet B and C, sTfR and the TfR-F-Index were significantly increased compared to Binet A patients (p<0.0001). The differences between Binet B and C were not significant. sTfR was increased in 85%, TfR-F-Index in 46% and the CRP-adjusted TfR-F-Index in 54% of the Binet B patients, in Binet C patients, 80%, 50% and 60% showed increases, respectively. sTfR and the TfR-F-Index decreased or even normalized following successful treatment. CONCLUSIONS: Similar to sTfR, the TfR-F-Index is strongly associated with tumor burden in patients with CLL. Thus, these parameters do not allow for a reliable diagnosis of ID in this patient group.

Alpha-fetoprotein expressing metastastic adenocarcinoma of the esophago-gastric junction responding favorably to capecitabine and oxaliplatin.

Alpha-fetoprotein-producing metastatic adenocarcinoma of the stomach or the esophago-gastric junction usually exhibits either no or only short-term remission while receiving palliative chemotherapy. We report on a 76-year-old male patient suffering from an unresectable alpha-fetoprotein-producing adenocarcinoma of the esophago-gastric junction with several liver metastases. He was treated with capecitabine and oxaliplatin-based combination therapy. A long-lasting major remission was observed resulting in a survival of 18.5 months.

Oxaliplatin and capecitabine-based chemoradiotherapy for gastric cancer--an extended phase I MARGIT and AIO trial.

PURPOSE: Adjuvant 5-fluorouracil-based chemoradiotherapy has been shown to improve the prognosis of gastric cancer. To optimize these results, in the present study oxaliplatin and capecitabine were used instead of 5-fluorouracil. We sought to determine the maximum tolerated dose and the dose-limiting toxicities (DLT) of these drugs in combination with intensity-modulated radiotherapy. METHODS AND MATERIALS: Patients with resected adenocarcinoma of the stomach or the gastroesophageal junction were included. They received two cycles of induction chemotherapy (oxaliplatin and capecitabine [XelOx] regimen). Using standard Phase I methodology, patients received 45 Gy in 1.8-Gy fractions either in combination with capecitabine 825 mg m(-1) twice a day (Dose Level [DL] I) or capecitabine in combination with weekly oxaliplatin 40 or 50 mg m(-1) (DL II and III). After the completion of chemoradiation, two additional cycles of XelOx were scheduled. RESULTS: A total of 32 patients were recruited. Only 1 of 6 patients evaluable on DL I had DLT. Of the first 6 patients on DL II, 1 patient experienced DLT, and 3 of the remaining patients had Grade 3 toxicity. Therefore, DL II was defined as the maximum tolerated dose and a total of 20 patients were treated at this DL. The most frequently observed toxicities (Common Toxicity Criteria Grades 1, 2 and 3) were, respectively, leukocytopenia in 5, 5, and 4 patients; nausea in 3, 7, and 3; and diarrhea in 4, 0, and 1. CONCLUSIONS: In summary, capecitabine 825 mg m(-1) twice a day (Days 1-33) and weekly oxaliplatin 40 mg m(-1) was safe and tolerable in combination with intensity-modulated radiotherapy. Furthermore, four cycles of XelOx could be applied before and after chemoradiotherapy in two thirds of the patients.
