Experience with the Groshong long-term central venous catheter☆

A study of the Groshong catheter in a gynecologic oncology population is presented, describing the catheters ease of insertion, and patient acceptance and compliance in catheter care. From December 1985 through November 1987, 72 Groshong catheters were inserted in 67 patients. The Groshong differs from conventional Hickman-type catheters in design and maintenance. Thirty-two of 72 catheters (44%) were inserted under local anesthesia. The remaining catheters were inserted under general anesthesia at the time of major gynecologic procedures. None of the cases required fluoroscopy. The insertion technique is less traumatic than conventional approaches because of a stainless steel tunneling device. The median duration of use was 191 days. There were no cases of pneumothorax or catheter occlusion. Catheter removal was required in four cases with skin infection unresponsive to local therapy and in two cases with bacteremia. One patient developed thrombosis of the right subclavian vein but was treated without catheter removal. One patient with a skin infection at the exit site accidentally dislodged her catheter. The overall complication rate was 11% (8 of 72 cases).

A phase II evaluation of cediranib in the treatment of recurrent or persistent endometrial cancer

PURPOSE Cediranib is a multi-tyrosine kinase inhibitor targeting vascular endothelial growth factor (VEGF), platelet-derived growth factor (PDGF), and fibroblast growth factor (FGF) receptors. This phase II study was conducted to assess activity and tolerability of single-agent cediranib in recurrent/persistent endometrial cancer. PATIENTS AND METHODS Eligible patients had recurrent or persistent endometrial cancer after receiving one or two prior cytotoxic regimens, measurable disease, and Gynecologic Oncology Group (GOG) performance status of ≤2 (≤1 if two prior cytotoxic regimens given). Cediranib 30mg orally daily for a 28daycycle was administered until disease progression or prohibitive toxicity. Microvessel density (MVD) was measured in tumor tissue from initial hysterectomy specimens and correlated with clinical outcome. Primary endpoints were tumor response and surviving progression-free for six months without subsequent therapy (6-month event-free survival [EFS]). RESULTS Of 53 patients enrolled, 48 were evaluable for cediranib efficacy and toxicity. Median age was 65.5 years, 52% of patients had received prior radiation, and 73% of patients received only one prior chemotherapy regimen. A partial response was observed in 12.5%. Fourteen patients (29%) had six-month EFS. Median progression-free survival (PFS) was 3.65 months and median overall survival (OS) 12.5 months. No grade 4 or 5 toxicities were observed. A trend towards improved PFS was found in patients whose tumors expressed high MVD. CONCLUSION Cediranib as a monotherapy treatment for recurrent or persistent endometrial cancer is well tolerated and met protocol set objectives for sufficient activity to warrant further investigation. MVD may be a useful biomarker for activity.

Comparison of Focus Groups on Cancer and Employment Conducted Face to Face or by Telephone

Findings from telephone focus groups have not been compared previously to findings from face-to-face focus groups. We conducted four telephone focus groups and five face-to-face focus groups in which a single moderator used the same open-ended questions and discussion facilitation techniques. This comparison was part of a larger study to gain a better understanding of employment experiences after diagnosis of gynecologic cancer. Offering the telephone option made it easier to recruit women from rural areas and geographically distant cities. Interaction between participants occurred in both types of focus group. Content analysis revealed that similar elements of the employment experience after cancer diagnosis were described by telephone and face-to-face participants. Participants disclosed certain emotionally sensitive experiences only in the telephone focus groups. Telephone focus groups provide useful data and can reduce logistical barriers to research participation. Visual anonymity might help some participants feel more comfortable discussing certain personal issues.

Employment and Quality of Survivorship Among Women With Cancer: Domains Not Captured by Quality of Life Instruments

BACKGROUND Many quality of life instruments assess the amount of paid work in combination with role function at home in the same items and do not specifically assess social support in the workplace. The goal of this study was to obtain womens views on the relationship between employment and health-related quality of life. METHODS A focus group and questionnaire study was conducted among 73 women with gynecologic cancer who were employed at diagnosis and 25 people who provided them with psychosocial support. RESULTS The women held a variety of blue collar and white collar jobs at diagnosis. Employment provided a strong sense of accomplishment and a welcome distraction during treatment. The employment experience was described as distinct from role function at home. No one equated working more hours with better quality of life. Social support at work could be poor at the same time that support from family and friends grew stronger. CONCLUSIONS The contribution to their quality of life that cancer survivors feel they receive from employment may not be linearly related to the quantity of their role function in the workplace. Employment-related items could be useful as an adjunct to standard quality of life measures.

The nuclear channel system in endometrial adenocarcinoma exposed to medroxyprogesterone acetate

The nuclear channel system (NCS), giant mitochondria and subnuclear glycogen form a triad of ultrastructural features observed in normal human endometrial epithelium in response to progestational steroids. Both the giant mitochondria and subnuclear glycogen have been described in endometrial adenocarcinoma, but the NCS has not. This article reports the development of the NCS in adenocarcinoma treated with medroxyprogesterone acetate. Previous studies suggest that the NCS in normal tissue is a response to the acyl group in the 17-beta position of the D-ring of some progestational steroids, such as medroxyprogesterone acetate. Medroxyprogesterone acetate was administered to 12 postmenopausal women with endometrial adenocarcinoma. Hysterectomies were performed 8 to 20 days after treatment. Pretreatment specimens were also obtained on 8 of the 12 patients. Using standard electron microscopy procedures, light microscopy on plastic semithin sections was first used to confirm the presence of tumor. Thin sections of malignant endometrium were prepared and evaluated ultrastructurally for progestational alterations. Abnormal giant mitochondria and subnuclear glycogen were found both before and after treatment. The third element of the triad, the NCS, was not observed in any of the available pretreatment biopsies, but was seen in three of the treated specimens. Thus it appears that the NCS is a response to the given progesterone therapy.

Continuous abdominal fascial closure: a randomized controlled trial of poly(l-lactide/glycolide)

OBJECTIVE The objective was to compare the handling characteristics and </=6 month clinical outcome using a No. 1 long-term absorbable multifilament suture poly(L-lactide/glycolide) (PLG) or the permanent monofilament (No. 1) polypropolene using a continuous fascial closure. METHODS During the 13-month study interval, 203 high-risk patients were enrolled in this randomized prospective trial. All were managed under a strict perioperative management protocol. RESULTS There was no clinically significant difference in patient demographics. Seventy percent carried a diagnosis of abdominal malignancy. The mean body mass index of the population was 33.1. Wound variables including incision length, incision site, measured subcutaneous tissue thickness, and method of subcutaneous dissection did not differ. During the evaluation of suture handling properties PLG was judged to be statistically superior (P < 0.001) in lack of springback, knot tie-down smoothness, knot security, knot strength, and surgical hand. The monofilament suture was judged superior (P < 0001) in ease of tissue passage. There was no difference in incisional pain, suture rejection, superficial wound dehiscence, infection, seroma, or hernia. CONCLUSION PLG suture represents a suitable nonpermanent suture alternative for fascial closure in patients at risk for poor wound outcome.

Nucleolar canalicular structure in extrauterine endometriosis

Under the influence of progesterone the unique intranuclear structure known as the nucleolar canalicular structure (NCS) develops in the human endometrium. This organelle was not described previously outside the uterus. In this report the cases of two patients in whom the NCS appeared in extrauterine endometriosis are presented.
