Clinical Records ROYAL MARSDEN NHS TRUST - PATIENT CASE NOTE ######:MRS ##### ####### 27 Aug 1998 Seen in the Follow Up Staging Clinic This 65 year old lady has been reviewed in the Breast staging clinic. As you know, she was originally diagnosed with a carcinoma of the left breast in 1974 and treated with a total mastectomy. This was followed with MEFUP chemotherapy. In 1982 she noticed a lump in the infraclavicular region which was excised and this was followed by radiotherapy. In 1994 she developed a tumour in the chest cavity that was diagnosed with a CT guided biopsy and this was treated with VAC chemotherapy and radiotherapy to the mediastinum. Since 1994 she had noticed a slight deterioration and earlier this year she had problems with occasional episodes of vomiting, nausea and general lethargy. She was found to have lymphadenopathy in the right supraclavicular fossa and was treated with Arimidex. Since being on Arimidex there was originally stablisation of her disease but recently it appears that the node has started to enlarge. On examination today, she has a 1.5x1cm lymph node in the right supraclavicular fossa and an essence of thickening probably due to previous therapy in the left supraclavicular fossa. She also has radiation changes in the lung which produced some physical sign at both bases and there was no evidence of abdominal organomegaly. Her recent staging investigations show that she has C5 carcinoma cells present in the lymph node fine needle aspirate. A right mammogram is unremarkable. An ultrasound of the liver was normal and a chest x-ray showed some soft tissue thickening present in the left axilla due to previous therapy. There is also some loss of volume in the left upper zone but no lung nodules seen. A bone scan shows evidence of degenerative changes but no specific evidence of bony metastases. Her thyroid function tests show that the TSH is 0.12 and her free T3 are 4 which indicates that the TSH is slightly low. This does not amount to primary hypothyroidism but it would be worth repeating the thyroid function tests in three months time. Overall, it appears that the patient has stable disease on Arimidex apart from in the right supraclavicular fossa. The Arimidex is not holding the disease completely and we feel that the best approach to management would be to consider some radiotherapy to the right supraclavicular fossa. She has previously had radiation therapy to the left clavicular region and mediastinum. We have discussed performing a CT scan of the thorax but she was unable to lie flat for the duration of the investigation some months ago. We shall ask our radiotherapy colleagues to review her and consider her for therapy. We shall review her again in the follow up clinic in six weeks time. 28/03/2003, 10:50:25 ROYAL MARSDEN NHS TRUST - PATIENT CASE NOTE ######:MRS ##### ####### 15 Dec 1993 General Surgical I reviewed this patient in clinic today. She has been followed up for a left breast carcinoma for which she was treated with a mastectomy. She had a prosthesis removed last year and has had some improvement in the symptoms of chest wall discomfort since then although she still gets quite sharp pains intermittently. She has been reviewed in the pain clinic local to where she lives but has not had much relief of her symptoms. She feels though that she can bear with these and does not want any further intervention at present. On examination today there is no sign of recurrence of her disease. Chest and abdominal examination were unremarkable. We will see her again in a year's time. 28/03/2003, 10:35:26 ROYAL MARSDEN NHS TRUST - DIAGNOSTIC RADIOLOGY - CT REPORT ######:#######,MRS ##### Exam 18 Dec Examination LIVER/THORAX/ABDOMEN/PELVIS Exam Number [NUM] Date of Birth 17 May 1933 Ref [HCA1] OUTPATIENT Clinical BR Verified by [HCA2] DIAGNOSIS: Carcinoma of breast. CT scans have been obtained through chest, abdomen and pelvis with oral contrast only. There is thickening in the left clavicular fossa and small- volume residual abnormalities in the mediastinum. Comparison is made with the most recent scan (21.7.95) and there is no discernible change by CT criteria. Lung changes, which may have been related to radiotherapy, are now less extensive. There are no abnormally-enlarged nodes in the retroperitoneum or pelvis. There are no focal hepatic masses. CONCLUSION: No CT evidence of disease progression. 28/03/2003, 12:35:06 ROYAL MARSDEN NHS TRUST - PATIENT CASE NOTE ######:MRS ##### ####### 24 Jan 1997 Seen in the Chemotherapy Clinic (TPFRIDAY) I saw ##### today in clinic. I am very pleased to say that she has had a complete response in her superior mediastinum and right supraclavicular fossa lymphadenopathy. There is some minimal thickening remaining in the soft tissues around the superior mediastinum and in fact it is felt that this might now be related to previous radiotherapy. To be honest, however, symptomatically there has been little in the way of benefit with overall palliative response of no change. She is tolerating the treatment fairly well. Interestingly she has had virtually complete alopecia with the treatment. She has been on warfarin for about the same amount of time and I wonder whether this may be partly responsible. We have given her a fourth cycle of treatment today and we will see her in three weeks for consideration of her fifth. 28/03/2003, 10:44:20
