      &lt;p&gt;The addition of trastuzumab (Herceptin) before and after surgery significantly improved event-free survival compared with neoadjuvant chemotherapy alone in women with HER2-positive locally advanced or inflammatory breast cancer, investigators in a multicenter European trial reported.&lt;/p&gt;
&lt;p&gt;Patients treated with trastuzumab had a 40% reduction in the hazard ratio for the composite endpoint of recurrence, progression, or death from any cause.&lt;/p&gt;
&lt;p&gt;&quot;Although locally advanced breast cancer is relatively infrequent in affluent countries compared with nonaffluent countries, it is still an area of medical need, especially in regions of the world where diagnosis tends to occur late for cultural or economic reasons,&quot; Luca Gianni, MD, of the National Cancer Institute in Milan, Italy, and colleagues wrote in the Jan. 30 issue of &lt;em&gt;The Lancet&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;Neoadjuvant chemotherapy has a key role in the management of patients with locally advanced and inflammatory cancers. Anthracycline- and taxane-based regimens have produced high response rates and rates of breast-conserving surgery for patients with operable breast cancer, the authors wrote.&lt;/p&gt;
&lt;p&gt;About 35% of locally advanced and 40% of inflammatory breast cancers are associated with HER2 amplification or overexpression. Trastuzumab, which targets HER2, has demonstrated efficacy as monotherapy and in combination with chemotherapy for patients with HER2-positive metastatic and early operable breast cancer, the authors continued.&lt;/p&gt;
&lt;p&gt;Trastuzumab does not have specific approval for treatment of locally advanced or inflammatory breast cancer and has not been studied extensively for those indications. So the investigators designed the neoadjuvant Herceptin (NOAH) study to assess the efficacy of neoadjuvant chemotherapy plus trastuzumab followed by adjuvant trastuzumab.&lt;/p&gt;
&lt;p&gt;The randomized trial compared the regimen versus neoadjuvant chemotherapy alone in 235 patients with newly diagnosed HER2-positive locally advanced or inflammatory breast cancer.&lt;/p&gt;
&lt;p&gt;The investigators conducted a parallel observational study involving 99 patients with newly diagnosed HER2-negative locally advanced or inflammatory breast cancer. Those patients too were treated with chemotherapy alone, which consisted of doxorubicin, paclitaxel, cyclophosphamide, methotrexate, and 5-FU.&lt;/p&gt;
&lt;p&gt;The primary endpoint was event-free survival, defined as the time from randomization to disease recurrence or progression or death from any cause.&lt;/p&gt;
&lt;p&gt;After a median follow-up of 3.2 years, the three-year event-free survival was 71% in the trastuzumab arm and 56% in the patients who received chemotherapy without trastuzumab. The difference translated into an unadjusted hazard ratio of 0.59 (95% CI 0.38 to 0.90, &lt;em&gt;P&lt;/em&gt;=0.013).&lt;/p&gt;
&lt;p&gt;Regression analysis confirmed that treatment with trastuzumab was the only factor that significantly affected event-free survival, resulting in a hazard ratio of 0.58 compared with the chemotherapy-only arm (&lt;em&gt;P&lt;/em&gt;=0.126).&lt;/p&gt;
&lt;p&gt;Three-year overall survival was not significantly different between the treatment arms of HER2-positive patients but trended in favor of the trastuzumab arm (87% versus 79%). The authors noted that the 17% crossover to treatment with trastuzumab may have lessened the observed survival difference.&lt;/p&gt;
&lt;p&gt;The HER2-negative patients had a three-year event-free survival of 67% and overall survival of 86%.&lt;/p&gt;
&lt;p&gt;Rates and severity of noncardiac adverse events were similar in all three treatment groups, the authors reported. Fewer patients in the trastuzumab arm maintained normal left ventricular ejection fraction (LVEF) throughout the study, but most reductions in LVEF were grade 1 in severity. Two patients had grade 2 (asymptomatic) reductions in LVEF, and two had reversible grade 3 decreases.&lt;/p&gt;
&lt;p&gt;Gianni and colleagues acknowledged that the benefit in the trastuzumab arm could have occurred as a result of both neoadjuvant and adjuvant use of trastuzumab. However, the magnitude of the benefit (HR 0.59) was greater and the number needed to treat was lower compared with adjuvant trials of trastuzumab, Melanie D. Seal, MD, and Stephen K. Chia, MD, of the British Columbia Cancer Agency in Vancouver, wrote in a commentary.&lt;/p&gt;
&lt;p&gt;&quot;Adjuvant studies require thousands of women to show survival benefits, at high cost and often long follow-up,&quot; Seal and Chia wrote. &quot;Studies such as NOAH illustrate the benefits and potential of neoadjuvant trials and should challenge the dogma of our current strategies of therapeutic trials in early-stage breast cancer.&quot;&lt;/p&gt;

                     title="Good Results in Poor-Risk Rectal Cancer (CME/CE)"
                     score="0.004"
                     href="http://www.medpagetoday.com/HematologyOncology/ColonCancer/tb/18169?impressionId=1265780571816"
                     
      &lt;p&gt;Patients with high-risk rectal cancer had high response and three-year survival rates on a regimen of preoperative chemotherapy, followed by standard chemoradiation and then surgical resection, according to results of a multicenter study.&lt;/p&gt;
&lt;p&gt;Three-fourths of patients had objective responses to neoadjuvant chemotherapy, increasing to 89% after chemoradiation, researchers reported online in &lt;em&gt;The Lancet Oncology&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;Additionally, 97% of patients who underwent surgery had microscopically clear surgical margins. At three years, 83% of patients remained alive, including almost 70% who were progression free.&lt;/p&gt;
&lt;p&gt;&quot;Intensification of systemic therapy with neoadjuvant combination chemotherapy before standard treatment is feasible in poor-risk, potentially operable rectal cancer, with acceptable safety and promising long-term outcomes,&quot; David Cunningham, MD, of the Royal Marsden Hospital in Sutton, England, and co-authors concluded.&lt;/p&gt;
&lt;p&gt;&quot;Future development of this multidisciplinary treatment strategy in randomized trials is warranted.&quot;&lt;/p&gt;
&lt;p&gt;Although surgery remains the primary and potentially curative therapy for localized rectal cancer, local recurrence rates as high as 40% have been reported with conventional resection.&lt;/p&gt;
&lt;p&gt;The introduction of standardized surgery and total mesorectal excision reduced local recurrence rates to less than 10%, which has been associated with improved survival, the authors noted.&lt;/p&gt;
&lt;p&gt;Preoperative radiotherapy and then chemoradiation further reduced the risk of local recurrence, but did not improve overall survival compared with surgery alone.&lt;/p&gt;
&lt;p&gt;Combination chemotherapy has led to higher response rates and progression-free survival compared with monotherapy for patients with advanced rectal cancer, the authors continued. Adjuvant chemotherapy containing oxaliplatin (Eloxatin) also has improved outcomes in resected colon cancer.&lt;/p&gt;
&lt;p&gt;Given that oxaliplatin-fluoropyrimidine combinations have become a preferred standard, investigators designed a clinical trial of high-risk rectal cancer to investigate preoperative treatment with oxaliplatin and capecitabine (Xeloda).&lt;/p&gt;
&lt;p&gt;A previous report involving the first 77 patients enrolled in the trial showed substantial tumor regression, rapid improvement in symptoms, and a high rate of clear surgical margins (&lt;em&gt;J Clin Oncol&lt;/em&gt; 2006; 24: 668-74).&lt;/p&gt;
&lt;p&gt;Nine treatment-related cardiac events occurred in eight of the 77 patients, prompting a protocol amendment to exclude patients with a recent history of clinically significant cardiac problems.&lt;/p&gt;
&lt;p&gt;The updated results comprised 105 patients, and only one cardiac event occurred after the change in eligibility criteria, the authors wrote.&lt;/p&gt;
&lt;p&gt;All of the patients had MRI-defined, poor-risk but nonmetastatic rectal cancer. Patients received four cycles of neoadjuvant chemotherapy over 12 weeks, followed by chemoradiotherapy consisting of a total radiation dose of 54 Gy administered over six weeks, plus daily capecitabine.&lt;/p&gt;
&lt;p&gt;After total mesorectal excision, patients received 12 weeks of adjuvant capecitabine.&lt;/p&gt;
&lt;p&gt;The primary endpoint was pathologic complete response, and median follow-up was 55 months.&lt;/p&gt;
&lt;p&gt;Radiologically confirmed response rates were 74% after neoadjuvant chemotherapy and 89% after chemoradiation. Of 97 patients who had surgery, 93 had microscopically clear margins, and 21 of 105 patients had pathologic complete responses.&lt;/p&gt;
&lt;p&gt;Three-year progression-free and overall survival were 68% and 83%, respectively. Among patients who had surgery, three-year, relapse-free survival was 74%.&lt;/p&gt;
&lt;p&gt;&quot;Our findings show the feasibility of neoadjuvant chemotherapy with capecitabine and oxaliplatin before chemoradiotherapy and total mesorectal excision, which accord with the initial results of this study,&quot; the authors declared.&lt;/p&gt;
&lt;p&gt;&quot;High radiological response rates to preoperative treatment were recorded, and the number of pathological complete responses surpassed the prespecified number needed to meet the primary objective of this trial.&quot;&lt;/p&gt;

                     score="-0.004"
                     href="http://www.medpagetoday.com/Oncology/OtherCancers/tb/18039?impressionId=1265780571816"
                     
      &lt;p&gt;Adjuvant chemoradiotherapy significantly improves survival of patients with resectable pancreatic cancer, according to medical records of almost 3,000 patients.&lt;/p&gt;
&lt;p&gt;Chemoradiotherapy extended median survival by more than 30% compared with surgical resection only, researchers reported in the January &lt;em&gt;Archives of Surgery&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;&lt;em&gt; &lt;/em&gt;In a multivariate analysis, adjuvant chemoradiotherapy proved to be one of only three predictors of improved survival, the other two being treatment at high-volume and academic centers.&lt;/p&gt;
&lt;p&gt;&quot;This analysis provides strong evidence in a real-world setting that postoperative chemoradiotherapy and possibly adjuvant radiotherapy alone improve clinical outcome in patients with pancreatic cancer,&quot; Relin Yang, MD, of the University of Miami, and colleagues wrote.&lt;/p&gt;
&lt;p&gt;&quot;We further substantiate that this benefit is independent of the improved clinical outcomes obtained at high-volume centers and teaching facilities,&quot; they added.&lt;/p&gt;
&lt;p&gt;&quot;Nonetheless, this benefit remains modest, underscoring that further investigation is needed to establish a better adjuvant regimen after complete resection of pancreatic cancer.&quot;&lt;/p&gt;
&lt;p&gt;Complete surgical resection remains the only curative option for patients with early-stage pancreatic adenocarcinoma. Fewer than 25% of patients have cancer amenable to resection. For that small subset of patients, the role of adjuvant therapy remains controversial, the authors wrote.&lt;/p&gt;
&lt;p&gt;To address the issue, Yang and colleagues analyzed data from a population-based cancer registry. They augmented the data&apos;s predictive potential with information related to patient demographics, comorbidities, treatment, and type of facility.&lt;/p&gt;
&lt;p&gt;The authors identified 2,877 patients whose pancreatic adenocarcinoma was diagnosed and treated surgically with curative intent from 1998 to 2002. About 60% of the patients were older than 65. Some 90% were white (86.7% non-Hispanic), and 90% had no history of alcohol abuse.&lt;/p&gt;
&lt;p&gt;The authors reported that 51.9% of patients received neither chemotherapy nor chemoradiotherapy. About 25% received chemoradiotherapy, and another 10% received chemotherapy alone. Most patients were treated at low-volume centers (57.6%) and nonteaching facilities (72.8%).&lt;/p&gt;
&lt;p&gt;Median overall survival was 15 months, and 90-day postsurgical survival was 88.8%. Patients younger than 40 had the best survival (25.7 months versus 13.4 months for patients older than 65, &lt;em&gt;P&lt;/em&gt;&amp;lt;0.001).&lt;/p&gt;
&lt;p&gt;Race, ethnicity, and abstention from alcohol and tobacco did not significantly influence survival. Survival decreased as a patient&apos;s poverty level increased. Localized disease, well-differentiated tumors, and smaller tumor size were associated with significantly better survival (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.001).&lt;/p&gt;
&lt;p&gt;Patients treated with surgery only had a significantly lower (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.001) median overall survival of 12.6 months compared with patients who received chemotherapy or radiation preoperatively (19.9 months) or postoperatively (17.0 months).&lt;/p&gt;
&lt;p&gt;Median survival was 18.2 months among patients treated at high-volume centers versus 13.1 months at low-volume centers (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.001). Treatment at a teaching facility was associated with a median survival of 19.8 months compared with 13.6 months for nonteaching facilities (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.001).&lt;/p&gt;
&lt;p&gt;Multivariate analysis correcting for comorbidities showed that postoperative chemoradiotherapy significantly reduced the mortality hazard ratio (HR 0.69, &lt;em&gt;P&lt;/em&gt;=0.04). The reduced hazard exceeded the benefit associated with treatment at a high-volume center (HR 0.85, &lt;em&gt;P&lt;/em&gt;&amp;lt;0.001) or at a teaching facility (HR 0.84, &lt;em&gt;P&lt;/em&gt;&amp;lt;0.001) and was independent of facility type.&lt;/p&gt;
&lt;p&gt;The authors confirmed findings from other studies showing a beneficial effect of treatment in high-volume and teaching facilities, and a benefit for all patients who receive adjuvant chemoradiotherapy, Nita Ahuja, MD, of Johns Hopkins, wrote in a commentary.&lt;/p&gt;
&lt;p&gt;However, the study had several prominent weaknesses: missing information on cancer stage in more than 50% of patients, unknown margin status, and no information on the type or duration of adjuvant therapy.&lt;/p&gt;
&lt;p&gt;The study also did not address another major controversy involving adjuvant therapy for pancreatic cancer.&lt;/p&gt;
&lt;p&gt;&quot;At the end of the day, the present study will do little to quell the debate over the relative benefits of adjuvant chemoradiotherapy compared with chemotherapy alone after surgical resection of pancreatic cancer,&quot; Ahuja wrote.&lt;/p&gt;
&lt;p&gt;North Americans have a bias toward adjuvant chemoradiotherapy, supported primarily by data from a single small randomized clinical trial and several retrospective studies, Ahuja continued. European clinicians favor adjuvant chemotherapy based on one large clinical trial showing a benefit for chemotherapy and another showing no survival advantage for chemoradiotherapy.&lt;/p&gt;
&lt;p&gt;&quot;The present study will do little to change the minds of either camp,&quot; Ahuja concluded.&lt;/p&gt;
&lt;div style=&quot;float:left;border-style:solid;border-width:1px;border-color:#8dabbc;font-family:arial;font-size:12px;background-color:#DBE9F2;padding:5px;&quot;&gt;&lt;p&gt;Neither Yang and co-authors nor Ahuja had any disclosures.&lt;/p&gt;&lt;/div&gt;&lt;div style=&quot;clear:both;&quot;&gt;&lt;/div&gt;
