A supervised, moderate- to high-intensity, combined resistance and aerobic exercise program is most effective for patients with breast cancer undergoing adjuvant chemotherapy. A home-based, low-intensity physical activity program represents a viable alternative for women who are unable or unwilling to follow the higher intensity program.
We analyzed the management of regional lymph nodes in 110 patients with squamous cell carcinoma of the penis treated at the Netherlands Cancer Institute between 1956 and 1989 with curative intent. Of 66 patients who presented with unsuspected nodes 57 were placed on a surveillance program, while lymph node dissection was performed in 5 (with adjuvant external radiation therapy in 1) and 4 were treated with external radiation therapy only. The management of 40 patients with clinically suspected nodes included surveillance in 5, lymph node dissection in 27 (with adjuvant radiotherapy in 11), biopsy in 4 and external radiation therapy in 4. Postoperative radiotherapy had been given if more than 2 nodes were involved or when extracapsular growth was observed. Overall, 25 patients had a regional recurrence, 5 of whom could be cured subsequently. All regional recurrences developed within 2 years after primary treatment. Analysis showed 100% survival in histologically proved node negative patients (stage pN0). The success of lymph node dissection was related to the extent of the metastatic spread and to the number of involved nodes. Patients with 1 positive node and unilateral inguinal involvement showed a statistically significant survival advantage compared to patients with more extensive spread. Considering the indications for node dissection we found a clear relationship among T category, grade and the probability of lymph node invasion. Patients with stage T1 tumors and stage T2, grades 1 and 2 tumors presented significantly less often with lymphatic invasion than those with other categories of disease and were less likely to have a regional recurrence after treatment of the primary tumor only. In these categories we recommend surveillance of the regional lymph nodes in patients who present with unsuspected nodes. However, patients with stage T2 grade 3, stage T3 and operable stage T4 tumors should undergo an immediate inguinal node dissection because of the high probability of clinically occult lymph node invasion (in our material more than 50%). With respect to the extent of the node dissection, we found that the likelihood of spread to the contralateral and/or pelvic regions was related to the number of invaded nodes in the inguinal region. We recommend contralateral node dissection and unilateral pelvic node dissection when 2 or more positive nodes are found in the dissected groin specimen. Primary pelvic node dissection should be performed in patients who present initially with cytologically or biopsy proved positive inguinal nodes.(ABSTRACT TRUNCATED AT 400 WORDS)
The treatment of the primary tumor in 110 patients with squamous cell carcinoma of the penis seen between 1956 and 1989 was reviewed. Small tumors had generally been treated by penis conserving methods, such as circumcision, local excision and external radiotherapy alone or after circumcision or local excision. Since 1982 we have used the neodymium:YAG laser as a penis conserving method. In 51 patients (46%) penis conserving treatment had been performed and 59 (54%) had undergone some form of amputation. Overall, 16 of 110 patients (15%) had local recurrence. The risk of local recurrence after penis conserving therapy was significantly related to T category, with 10% local recurrences in stage T1 tumors in contrast to 32% and 100% in stages T2 and T3 tumors, respectively. All of the recurrences in patients with stage T1 tumors were strictly local and all were salvaged. In our view penis conserving therapy is a safe procedure in patients with stage T1 tumors and should always be attempted first. Amputation is considered to be overtreatment in these cases. Of 6 recurrences in the conservatively treated stage T2 disease group 4 were strictly local. These were all well or moderately differentiated tumors, not exceeding 3.5 cm. in diameter. We suggest penile conservation for this subgroup of T2 tumors. However, partial amputation is recommended for poorly differentiated stage T2 tumors. Local failure was observed in all stage T3 tumors treated with external radiation. In general, penis conservation in stage T3 tumors should not be attempted with the treatment modalities available to date. Comparing the different methods of penis conservation, used in 49 stages T1 and T2 tumors, no difference in local recurrence rate (18%) was observed among surgery, laser and external beam radiation. In view of the low morbidity, cutting and coagulation properties and minimal tissue changes, use of the neodymium:YAG laser would be our first choice of treatment modality. Penile conservation should be attempted only when frequent and long lasting followup is guaranteed, since local recurrences can appear as late as 8 years after primary treatment.
Our findings indicate that cognitive impairment after systemic treatment occurs in a subset of BC patients. The predictive value of demographic and psychosocial factors in cognitive impairment should be further investigated in a larger sample of impaired patients.
Among 118 patients with squamous cell carcinoma of the penis treated at our cancer institute between 1956 and 1989, we analyzed the accuracy of classification, using the tumor, nodes and metastasis system. We analyzed the role of lymphography, computerized tomography and fine needle aspiration cytology as additional staging procedures. The primary tumor (T category) was classified incorrectly in 26% of the cases. Overstaging was noted in 10% of the cases because of unsuspected infiltration and overstaging was noted in 16%. Overstaging occurred because of edema and infection masking the actual size and giving a misconception of infiltration, and also because of primary presentation as large exophytic tumors with no or minimal histopathological infiltration. When the regional lymph nodes were categorized simply as positive or negative 80% of the tumors were classified correctly and 20% incorrectly (13% were false positive and 7% were false negative). Regional lymph node invasion that escaped clinical examination was not detected by any imaging examination or fine needle aspiration cytology study. Positive findings were found only in patients with clinically suspected nodes. The classification of regional nodes by clinical examination only is hardly improved by additional imaging studies. Clinical decisions with respect to the management of regional lymph nodes should not be based on negative findings of lymphangiography, computerized tomography or fine needle aspiration cytology. In patients with proved metastasis additional imaging may be of some help in the detection of pelvic node invasion and the determination of the extent of involvement. We recommend lymphangiography as the examination of choice.
Docetaxel, a taxane antitumor agent, was administered to 24 patients by a 1-h intravenous infusion at a dose level of 100 mg/m(2) with pharmacokinetic monitoring. The plasma concentration-versus-time data were fitted with a three-compartment model. The mean area under the curve (AUC) for docetaxel was 3.1 +/- 0.9 h. mg/l and the clearance was 34.8 +/- 9.3 l/h per m(2). There was considerable interpatient pharmacokinetic variability. In 33% of the patient population, metabolites were detected in plasma samples collected 5-30 min after the end of the infusion. The cyclized oxazolidinedione metabolite M4 was most frequently present and was detected in 8 out of 24 patients with maximal concentrations between 0.022 and 0.23 mg/l. Logistic regression analysis was performed to predict M4 docetaxel metabolism. In the final model, alanine aminotransferase and alkaline phosphatase levels were the strongest predictors. No relationship was found between M4 metabolism and percentage decrease in neutrophil count in this study. Three patients with high M4 concentrations in plasma during course 1 suffered from most pronounced fluid retention (grade 2-3) after two to five courses.
Background: This study evaluated the effectiveness of a screening and stepped care program (the TES program) in reducing psychological distress compared with care as usual (CAU) in patients with metastatic colorectal cancer starting with first-line systemic palliative treatment. Patients and Methods: In this cluster randomized trial, 16 hospitals were assigned to the TES program or CAU. Patients in the TES arm were screened for psychological distress with the Hospital Anxiety and Depression Scale and the Distress Thermometer/Problem List (at baseline and 10 and 18 weeks). Stepped care was offered to patients with distress or expressed needs, and it consisted of watchful waiting, guided self-help, face-to-face problem-solving therapy, or referral to specialized mental healthcare. The primary outcome was change in psychological distress over time, and secondary outcomes were quality of life, satisfaction with care, and recognition and referral of distressed patients by clinicians. Linear mixed models and effect sizes were used to evaluate differences. Results: A total of 349 patients were randomized; 184 received the TES program and 165 received CAU. In the TES arm, 60.3% of the patients screened positive for psychological distress, 26.1% of which entered the stepped care program (14.7% used only watchful waiting and 11.4% used at least one of the other treatment steps). The observed low use of the TES program led us to pursue a futility analysis, which showed a small conditional power and therefore resulted in halted recruitment for this study. No difference was seen in change in psychological distress over time between the 2 groups (effect size, −0.16; 95% CI, −0.35 to 0.03; P>.05). The TES group reported higher satisfaction with the received treatment and better cognitive quality of life (all P<.05). Conclusions: As a result of the low use of stepped care, a combined screening and treatment program targeting psychological distress in patients with metastatic colorectal cancer did not improve psychological distress. Our results suggest that enhanced evaluation of psychosocial concerns may improve aspects of patient well-being.
