In patients initially staged as unresectable this may be achieved with neoadjuvant treatment which is usually chemoradiotherapy based. We report the case of a 46-year-old patient with an unresectable, locally advanced pancreatic cancer (pT4 Nx cM0 G2) who was treated with a sequential neoadjuvant chemotherapy regimen consisting of 2 cycles of nab-paclitaxel plus gemcitabine followed by 4 cycles of FOLFIRINOX. Neoadjuvant chemotherapy resulted in secondary resectability (R0 resection). After 2 cycles of nab-paclitaxel plus gemcitabine, the patient already had a complete metabolic remission as measured by integrated fludeoxyglucose ((18)F) positron emission tomography and computerized tomography. After a follow-up of 18 months the patient is alive without progression of disease. We propose to assess the clinical benefit of sequencing the combinations nab-paclitaxel plus gemcitabine and FOLFIRINOX as neoadjuvant therapy for patients with locally advanced and initially unresectable pancreatic cancer in a controlled clinical trial.}, language = {en} } @article{WilhelmSmetakSchaeferEckartetal.2014, author = {Wilhelm, Martin and Smetak, Manfred and Schaefer-Eckart, Kerstin and Kimmel, Brigitte and Birkmann, Josef and Einsele, Hermann and Kunzmann, Volker}, title = {Successful adoptive transfer and in vivo expansion of haploidentical γδ T cells}, series = {Journal of Translational Medicine}, volume = {12}, journal = {Journal of Translational Medicine}, number = {45}, doi = {10.1186/1479-5876-12-45}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-117290}, year = {2014}, abstract = {Background: The primary aim of this pilot study was to determine the feasibility and safety of an adoptive transfer and in vivo expansion of human haploidentical gamma delta T lymphocytes. Methods: Patients with advanced haematological malignancies who are not eligible for allogeneic transplantation received peripheral blood mononuclear cells from half-matched family donors. For that, a single unstimulated leukapheresis product was incubated with both the anti-CD4 and anti-CD8 antibodies conjugated to paramagnetic particles. The depletion procedure was performed on a fully automated CliniMACS (R) device according to the manufacturer's instructions. On average, patients received 2.17 x 10(6)/kg (range 0.9-3.48) γδ T cells with <1\% CD4-or CD8-positive cells remaining in the product. All patients received prior lymphopenia-inducing chemotherapy (fludarabine 20-25 mg/m(2) day -6 until day -2 and cyclophosphamide 30-60 mg/kg day -6 and -5) and were treated with 4 mg zoledronate on day 0 and 1.0x10(6) IU/m(2) IL-2 on day +1 until day +6 for the induction of gamma delta T cell proliferation in vivo. Results: This resulted in a marked in vivo expansion of donor γδ T cells and, to a lower extent, natural killer cells and double-negative αβ T cells (mean 68-fold, eight-fold, and eight-fold, respectively). Proliferation peaked by around day +8 and donor cells persisted up to 28 days. Although refractory to all prior therapies, three out of four patients achieved a complete remission, which lasted for 8 months in a patient with plasma cell leukaemia. One patient died from an infection 6 weeks after treatment. Conclusion: This pilot study shows that adoptive transfer and in vivo expansion of haploidentical γδ T lymphocytes is feasible and suggests a potential role of these cells in the treatment of haematological diseases.}, language = {en} } @article{WiegeringIsbertDietzetal.2014, author = {Wiegering, Armin and Isbert, Christoph and Dietz, Ulrich A. and Kunzmann, Volker and Ackermann, Sabine and Kerscher, Alexander and Maeder, Uwe and Flentje, Michael and Schlegel, Nicolas and Reibetanz, Joachim and Germer, Christoph-Thomas and Klein, Ingo}, title = {Multimodal therapy in treatment of rectal cancer is associated with improved survival and reduced local recurrence - a retrospective analysis over two decades}, doi = {10.1186/1471-2407-14-816}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-110606}, year = {2014}, abstract = {Background The management of rectal cancer (RC) has substantially changed over the last decades with the implementation of neoadjuvant chemoradiotherapy, adjuvant therapy and improved surgery such as total mesorectal excision (TME). It remains unclear in which way these approaches overall influenced the rate of local recurrence and overall survival. Methods Clinical, histological and survival data of 658 out of 662 consecutive patients with RC were analyzed for treatment and prognostic factors from a prospectively expanded single-institutional database. Findings were then stratified according to time of diagnosis in patient groups treated between 1993 and 2001 and 2002 and 2010. Results The study population included 658 consecutive patients with rectal cancer between 1993 and 2010. Follow up data was available for 99.6\% of all 662 treated patients. During the time period between 2002 and 2010 significantly more patients underwent neoadjuvant chemoradiotherapy (17.6\% vs. 60\%) and adjuvant chemotherapy (37.9\% vs. 58.4\%). Also, the rate of reported TME during surgery increased. The rate of local or distant metastasis decreased over time, and tumor related 5-year survival increased significantly with from 60\% to 79\%.

Findings were then stratified to the time periods of treatment with surgery alone, 5-Fluorouracil-only and contemporary combined systemic perioperative chemotherapy strategies, respectively. Results Despite R0 D2 gastrectomy (n = 560), 49.6\% (±5.4\%) of the patients were diagnosed with tumour recurrence and 15.5\% (±1.8\%) developed metaPC after a median time of 17.7 (15.1-20.3) months after surgery resulting in a tumour related mortality of 100\% with a median survival of 3.0 months (2.1 - 4.0). Independent risk factors for the development of metaPC were serosa positive T-category, nodal positive-status, signet cell and undifferentiated gradings (G3/G4). Contemporary systemic combination chemotherapy did not improve the incidence and prognosis of metaPC (p = 0.54). Conclusions Despite significant improvements in the overall survival for the complete cohort with gastric cancer over time, those patients with metaPC did not experience the same benefits.

However, the role of adjuvant postoperative CTx (postCTx) in addition to neoadjuvant preoperative CTx (preCTx) in this setting remains controversial. Methods Between 4/2006 and 12/2013, 116 patients with locally advanced gastric cancer were treated with preCTx. 72 patients (62 \%), in whom complete tumor resection (R0, subtotal/total gastrectomy with D2-lymphadenectomy) was achieved, were divided into two groups, one of which receiving adjuvant therapy (n = 52) and one without (n = 20). These groups were analyzed with regard to survival and exclusion criteria for adjuvant therapy. Results Postoperative complications, as well as their severity grade, did not correlate with fewer postCTx cycles administered (p = n.s.). Long-term survival was shorter in patients receiving postCTx in comparison to patients without postCTx, but did not show statistical significance. In per protocol analysis by excluding two patients with perioperative death, a shorter 3-year survival rate was observed in patients receiving postCTx compared to patients without postCTx (3-year survival: 71.2 \% postCTx group vs. 90.0 \% non-postCTx group; p = 0.038). Conclusion These results appear contradicting to the anticipated outcome. While speculative, they question the value of post-CTx.

We report the case of a 60-year-old patient with an R0-resected node-positive adenocarcinoma of the papilla of Vater of an initially diagnosed intestinal subtype who developed pulmonary metastases 2 months after adjuvant gemcitabine chemotherapy and, subsequently, liver metastases. Palliative combination chemotherapy with standard regimens for intestinal-type adenocarcinoma (FOLFOX and FOLFIRI) failed. However, subsequent combination chemotherapy with nanoparticle albumin-bound paclitaxel and gemcitabine, a regimen with proven efficacy in metastatic adenocarcinoma of the pancreas, resulted in a durable, very good partial remission. Treatment was manageable and well tolerated. Primary tumor and metastatic tissue were reassessed by immunohistochemistry and had to be reclassified to a mixed phenotype containing predominant elements of the pancreatobiliary subtype. Our case suggests that combination chemotherapy with nanoparticle albumin-bound paclitaxel and gemcitabine could represent a promising option for the treatment of this rare disease and warrants further investigation within controlled clinical trials. Moreover, thorough characterization of ampullary carcinomas by histomorphology and additional immunohistochemistry should become mandatory in order to start a chemotherapeutic regimen tailored for the definitive subtype.}, language = {en} } @article{HefnerBerberichLanversetal.2017, author = {Hefner, Jochen and Berberich, Sara and Lanvers, Elena and Sanning, Maria and Steimer, Ann-Kathrin and Kunzmann, Volker}, title = {New insights into frequency and contents of fear of cancer progression/recurrence (FOP/FCR) in outpatients with colorectal carcinoma (CRC) receiving oral capecitabine: a pilot study at a comprehensive cancer center}, series = {Patient Preference and Adherence}, volume = {11}, journal = {Patient Preference and Adherence}, doi = {10.2147/PPA.S142784}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-158476}, pages = {1907-1914}, year = {2017}, abstract = {Background: Fear of cancer progression/recurrence (FOP/FCR) is considered one of the most prevalent sources of distress in cancer survivors and associated with lower quality of life and functional impairment. Detailed measures of FOP/FCR are needed because little is known about the knowledge of FOP/FCR, its associations with the patient-doctor relationship, and the rate of adequate therapy. Colorectal cancer (CRC) is one of the most prevalent cancer entities, and oral capecitabine is widely prescribed as treatment. Therefore, we initiated a pilot study to expand the literature on FOP/FCR in CRC outpatients receiving capecitabine and to generate hypotheses for future investigations. Methods: This study included 58 patients treated at a comprehensive cancer center. FOP/FCR was assessed with the Fear of Progression Questionnaire (FOP-Q-SF). Satisfaction with the relationships with doctors was assessed with the Patient-Doctor Relationship Questionnaire-9 (PRDQ-9). Levels of side effects were rated by the patients on a visual analog scale. Clinical data were extracted from the charts. Results: A total of 19 out of 58 patients (36\%) suffered from FOP/FCR according to our assessment. Levels of FOP/FCR seemed to be mostly moderate to high. Only four out of the 19 distressed patients (21\%) were treated accordingly. Typical side effects of oncological treatment were associated with higher FOP/FCR. Satisfaction with doctor-patient relationships was not associated with FOP/FCR. Regarding single items of FOP/FCR, three out of the five most prevalent fears were associated with close relatives. Discussion: FOP/FCR occurred frequently in more than one in three patients, but was mostly untreated in this sample of consecutive outpatients with CRC receiving oral capecitabine. In detail, most fears were related to family and friends. In addition to an unmet need of patients, our data indicate sources of distress not considered thus far.

Methods 137 consecutive patients with CRLM, were analyzed regarding survival data, clinical, histological data and treatment. Results were stratified according to the occurrence of pulmonary metastases and metastases resection. Results 39\% of all patients with liver resection due to CRLM developed additional lung metastases. 44\% of these patients underwent subsequent pulmonary resection. Patients undergoing pulmonary metastasectomy showed a significantly better five-year survival compared to patients not qualified for curative resection (5-year survival 71.2\% vs. 28.0\%; p = 0.001). Interestingly, the 5-year survival of these patients was even superior to all patients with CRLM, who did not develop pulmonary metastases (77.5\% vs. 63.5\%; p = 0.015). Patients, whose pulmonary metastases were not resected, were more likely to redevelop liver metastases (50.0\% vs 78.6\%; p = 0.034). However, the rate of distant metastases did not differ between both groups (54.5 vs.53.6; p = 0.945).

Aspects of a close patient-doctor relationship are reported to be correlated with adherence to oral anticancer drugs, but data on capecitabine are scarce. Patients and methods: Sixty-four outpatients with a diagnosis of cancer and prescribed capecitabine were recruited from a German Comprehensive Cancer Center. We used the Patient-Doctor Relationship Questionnaire (PDRQ-9), the Medical Adherence Rating Scale (MARS), the Beliefs about Medicines Questionnaire (BMQ), and the Satisfaction with Information about Medicines Scale (SIMS) to assess patients' perceptions and behavior. Medical data were extracted from the charts. Results: Non-adherence was reported by 20\% of the 64 participants. The perceived quality of the patient-doctor relationship was high in general, but it did not emerge as a predictor of adherence in our survey (odds ratio [OR]=0.915, P=0.162, 95\% CI=0.808-1.036). However, beliefs about medicine (OR=1.268, P<0.002; 95\% CI=1.090-1.475) as well as satisfaction with information about medicine (OR=1.252, P<0.040, 95\% CI=1.010-1.551) were predictors of adherence and the quality of the patient-doctor relationship was correlated with both variables (r=0.373, P=0.002 for SIMS sum score; r=0.263, P=0.036 for BMQ necessity/concern difference). Overall, adherence to capecitabine was high with a conviction that the therapy is necessary. However, concerns were expressed regarding the long-term effect of capecitabine use. Patients have unmet information needs regarding interactions of capecitabine with other medicines and the impairment of their intimate life. Conclusions: In order to ensure adherence to capecitabine, our results seem to encourage the default use of modern and perhaps more impersonal means of information brokerage (eg, email, internet).
