- Purpose Evaluation of primary tumor-, treatment-, and patient-related factors predicting relapse pattern, risk, and survival after relapse with the aim to design a risk-adapted, tumor- directed surveillance program for patients with localized rhabdomyosarcoma (RMS). Patients and Methods One thousand one hundred sixty-four patients with nonmetastatic RMS achieved complete remission at the end of multimodal therapy in the consecutive trials of the Cooperative Weichteilsarkom Studiengruppe (CWS)-81, CWS-86, CWS-91, and CWS-96 between 1980 and 2002 ( median follow-up, 5 years). Three hundred thirty-seven of these individuals developed either locoregional, metastatic, or combined relapses. Predictive factors for relapse, its pattern, and postrelapse survival were analyzed. Results Age, histology, tumor size, tumor site, postsurgical stage, and omission of radiotherapy were identified as factors associated with an increased relapse risk in multivariate analyses. Relapse rates did not differ among the CWS trials. Median time to relapse was 1.43 years from first diagnosis ( range, 0.13 to 13.5 years). There were 217 locoregional, 72 metastatic, and 48 combined recurrences. Only two patients developed metastases more than 4 years after diagnosis, and both had combined recurrences. Five-year postrelapse survival was 24%. Patient subsets with consistent relapse pattern, risk, and postrelapse survival rates were identified on the basis of histologic subtype and tumor size. Conclusion Initial patient and tumor characteristics predict pattern and risk of relapse and also correlate with postrelapse survival probabilities. In localized RMS, tumor- directed follow-up should focus on the primary site. Screening for metastatic relapse may not be necessary more than 4 years after diagnosis. The identification of subgroups with distinctive pattern and risk of relapse may be used to develop risk-adapted, tumor- directed guidance for detection of recurrent disease in localized RMS.

Journal article (peer-reviewed)abstract
- Context: Pediatric cancer treatment may imply an increased risk of hypogonadism, leading to metabolic disorders and osteoporosis. Such complications are potentially preventable. Objective: The aim of this study was to assess diagnosis- and treatment-dependent risk of hypogonadism in male childhood cancer survivors (CCS). Design: Male CCS who were treated during the period 1970-2002 and who in 2004 were 18-45 yr of age were eligible. Setting: The study was conducted in a university hospital clinic. Patients: A consecutive group of CCS treated at Lund University Hospital was selected for the study, of whom 151 (38%) agreed to participate. Furthermore, 141 healthy fertile men served as controls. Interventions: We measured serum levels of free and total testosterone, SHBG, and LH. Main Outcome Measures: Odds ratios (OR) for biochemical hypogonadism, defined as total testosterone less than 10 nmol/liter and/or LH above 10 IU/liter, were calculated and related to type of cancer, treatment received, as well as testicular volume. Results: Hypogonadism was more commonly detected in CCS than in controls (OR, 6.7; 95% CI, 2.7, 17). The increased presence of hypogonadism was noted in the following treatment groups: brain surgery, chemotherapy (with and without radiotherapy), and testicular irradiation. Low total testicular volume (

An Everyday Struggle - Swedish Families' Lived Experiences During a Child's Cancer Treatment
- 2009
-
In: Journal of Pediatric Nursing. - : Elsevier. - 0882-5963 .- 1532-8449. ; 24:5, s. 423-432
-
Journal article (peer-reviewed)abstract
- The aim was to elucidate families' lived experience during a child's cancer treatment. Interviews were conducted with members of 11 affected families. A hermeneutical phenomenological approach was chosen. "Focus on the ill child-An everyday struggle" emerged as an essential theme. The families' lived experience of daily life was described as "feeling drained," "disrupting family life," "feeling locked up and isolated," "retaining normality," "becoming experts," and "changing perspectives." The result indicates that life during a child's cancer treatment is a taxing period and that the entire family is in need of support to ease their burdens. © 2009 Elsevier Inc. All rights reserved.

Striving to survive : Families' lived experiences when a child is diagnosed with cancer
- 2005

Journal article (peer-reviewed)abstract
- When a child is ill with cancer, this affects the whole family for long periods. The aim of this study was to elucidate the family's lived experience when a child in the family was diagnosed with cancer. A descriptive inductive design with a hermeneutic phenomenological approach including interviews with 17 families (parents, children, and siblings) was chosen. The families' lived experience was described as a 2-fold essential theme comprising "a broken life world" and an immediate "striving to survive." The families' secure everyday life disappeared and was replaced by fear, chaos, and loneliness. When striving to make the child and the family survive, family members strove to feel hope and have a positive focus, to gain control, and to feel close to other people. Phenomenological human science research can deepen the understanding of the meaning of being a family with a child who is ill with cancer and can help pediatric oncology staff become increasingly thoughtful, and thus better prepared to take action to diminish the chaos occurring in the family. © 2005 by Association of Pediatric Oncology Nurses.

Journal article (peer-reviewed)abstract
- Twenty-eight cases of hepatitis C virus (HCV) infection were identified in children in a pediatric oncology ward during 2 nosocomial outbreaks. HCV infection spontaneously cleared in 6 patients (21%). Eleven patients with persistent HCV viremia who had malignant diseases in remission after treatment were given a 48-week course of combined therapy with interferon-alpha (5x106 U 3 times weekly) and oral ribavirin (15 mg/kg/d). Seven (64%) of the 11 patients had sustained virological responses 6 and 12 months after cessation of therapy. Side effects were common but generally were mild or moderate.

Five-year results in Ewing's sarcoma. The Scandinavian Sarcoma Group experience with the SSG IX protocol
- 2000
-
In: European Journal of Cancer. - 1879-0852. ; 36:7, s. 875-880
-
Journal article (peer-reviewed)abstract
- The first Scandinavian protocol for Ewing's sarcoma, SSG IV, resulted in a local control rate of 74% and 5-year metastasis-free survival (MFS) of 43%. The second protocol, SSG IX, was started in order to improve upon these results. It featured four chemotherapy cycles, each consisting of two courses of VAI (vincristine, doxorubicin, ifosfamide) alternating with one course of PAI (cisplatin, doxorubicin, ifosfamide) at 3-weekly intervals. Total treatment time was 35 weeks. Local therapy was given at week 9. Inoperable or non-radically operated patients received hyperfractionated accelerated radiotherapy 1.5 Gy twice daily between chemotherapy courses to a total dose of 42-60 Gy, depending on surgical radicality and tumour localisation. 88 patients were included (58 male, 30 female, mean age 20 years; range 5-65 years). The tumour (73 M0 and 15 M1) was located centrally in 31 patients (35%), in the extremities in 34 (39%) and other sites in 23 (26%) of cases. The median size of tumour was 10 cm (range 2-23), soft tissue was invaded in 87%. Surgery was the local therapy for 60 (68%) patients: amputation in 8 and local excision in 52. The surgical margins were wide in 35 patients, marginal in 14 and intralesional in 3. Radiotherapy was given to 17 non-radically operated patients postoperatively and to 28 patients with inoperable tumours primarily. Histological responses were evaluated in 52 patients. 9 local recurrences were observed (10%). Distant metastases developed in 24 M0 patients (33%). The estimated 5-year MFS was 58% and overall survival (OS) 70% for M0 and 27% and 28% for M1 patients, respectively. Survival was favourable in patients with non-metastatic extremity tumours (90%) and tumours operated with wide margins (90%). Patients with a total necrosis after chemotherapy had a better OS than those with a partial or poor response (P=0.003). The toxicity (World Health Organisation) was acceptable (gastrointestinal G1-2; haematological G3-4). The SSG IX protocol gave better local control and survival rates than the SSG IV. Whether this is due to a higher therapeutic efficacy of the present protocol cannot be ascertained in this comparison with a historical control.

Neoadjuvant chemotherapy with high-dose ifosfamide, high-dose methotrexate, cisplatin, and doxorubicin for patients with localized osteosarcoma of the extremity: A joint study by the Italian and Scandinavian Sarcoma Groups
- 2005

In: Journal of Clinical Oncology. - 1527-7755. ; 23:34, s. 8845-8852

Journal article (peer-reviewed)abstract
- Purpose To explore the effect of high-dose ifosfamide in first-line treatment for patients <= 40 years of age with nonmetastatic osteosarcoma of the extremity. Patients and Methods From March 1997 to September 2000, 182 patients were evaluated. Primary treatment consisted of two blocks of high-dose ifosfamide (15 g/m(2)), methotrexate (12 g/m(2)), cisplatin (120 mg/m(2)), and doxorubicin (75 mg/m(2)). Postoperatively, patients received two cycles of doxorubicin (go mg/m(2)), and three cycles each of high-dose ifosfamide, methotrexate, and cisplatin (120 to 150 mg/m(2)). Granulocyte colony-stimulating factor support was mandatory after the high-dose ifosfamide/cisplatin/doxorubicin combination. Results No disease progression was recorded during primary chemotherapy, 164 patients (92%) underwent limb-salvage surgery, four patients (2%) underwent rotation plasty, and 11 patients (6%) had limbs amputated. Three (1.6%) patients died as a result of treatment-related toxicity, and one died as a result of pulmonary embolism after pathologic fracture. Grade 4 neutropenia and thrombocytopenia followed 52% and 31% of all courses, respectively, and mild to severe nephrotoxicity was recorded in 19 patients (10%). The median received dose-intensity compared with protocol was 0.82. With a median follow-up of 55 months, the 5-year probability of event-free survival was 64% (95% CI 57% to 71%) and overall survival was 77% (95% CI 67% to 81%), whereas seven patients (4%) experienced local recurrence. Conclusion The addition of high-dose ifosfamide to methotrexate, cisplatin, and doxorubicin in the preoperative phase is feasible, but with major renal and hematologic toxicities, and survival rates similar to those obtained with four-drug regimens using standard-dose ifosfamide. Italian Sarcoma Group/Scandinavian Sarcoma Group study I showed that in a multicenter setting, more than 90% of patients with osteosarcoma of the extremity can undergo conservative surgery.
