Q

Investigation of breast cyst

A

The cyst will be aspirated and if there is blood in the aspirate, this will be sent for cytology studies to exclude cancer. If there’s a residual mass after aspiration a biopsy is taken to check for cancer

Centrally
27
Prognosis in large cell lung cancer
Poor
28
What is a pancoast tumour?
Apical tumour
29
Complications of pancoast tumour
SVC obstruction Horners syndrome Brachial plexus involvement (upper limb weakness)
30
Cancer caused by asbestos exposure
Mesothelioma
31
Site of mesothelioma
Pleura
32
Main risk factor for empyema
Recent pneumonia that hasn't responded to antibiotics
33
Management of empyema
Broad spectrum abx Chest drain If unsuccessful, surgery
34
Risk factors for renal cell cancer
The main risk factors are older age, smoking, hypertension, obesity and family history. Lots of hereditary syndromes increase risk including Von-Hippel Lindau syndrome, tuberous sclerosis, Birt-Hogg-Dube syndrome and hereditary papillary renal cell carcinoma
35
Age of testicular torsion
First year of life or adolescence
36
What is Prehn's sign and what does it indicate?
Pain on lifting testicle. Testicular torsion
37
What is extra-vaginal torsion?
Extra-vaginal torsion is when the tunica vaginalis can tort with the spermatic cord as it isn’t yet attached, which affects boys in utero and the first year of life.
38
What is intra-vaginal torsion?
Intra-vaginal torsion is if the spermatic cord torts within the tunica vaginalis, which is seen primarily in adolescence
39
Management of CLL
May use "watch and wait" approach. Medications that may be used include chemotherapies, tyrosine kinase inhibitors, monoclonal antibodies and steroids (used in frail patients). In patients with few comorbidities, allogenic stem cell transplant can be used
40
What may be seen on blood film in CLL?
Smudge cells
41
Natural progression of CML
Typically, there is a chronic phase of 3-5 years with few symptoms and the patient is stable. This is followed by an accelerated phase of around a year where symptoms become more severe and finally a blast crisis, which is severe and resembles acute leukaemia with poor prognosis
42
Age associated with AML
Older adults
43
Which malignancy is associated with auer rods on blood smear?
AML
44
Management of AML
Supportive (treat anaemia, treat thrombocytopaenia, treat infections, consider allopurinol / raspuricase, hydroxycarbamide to for cytoreduction if needed) Induction chemo Maintenance chemo Stem cell transplant
45
Most common type of non-Hodgkin lymphoma
Diffuse large B cell lymphoma
46
Presentation of diffuse large B cell lymphoma
more common in younger people and usually presents as a rapidly enlarging mass
47
First line test for lymphoma diagnosis
Excisional biopsy (core biopsy if patient not fit)
48
Most common type of Hodgkin lymphoma
Nodular sclerosis
49
Prognosis in Hodgkin lymphoma
Good
50
Treatment of lymphoma
Varies depending on type and patient but chemo is key
51
How is a biopsy for thyroid cancer obtained?
Fine needle aspiration
52
Monitoring for recurrence of thyroid cancer
Thyroglobulin levels
53
What does superficial BCC look like?
red, scaly, irregular plaque with micro-erosions and a thin, clear, border
54
What does morphoeic BCC look like?
irregular boarders and a scar like plaque
55
What does basosquamous BCC look like?
Lesions may have central crusting and are often large and fast growing
56
What does Gorlin syndrome predispose to?
BCC
57
What does an SCC lesion look like?
ulcerating with raised, crusted edges
58
What does Bowen disease predispose to?
SCC

Characteristics of acral lentiginous melanoma
Occurs under nails or on palms or soles
62
Most common brain tumour in adults
Glioblastoma multiforme
63
Complications of ovarian cancer
Complications include ascites, pleural effusions and adhesions leading to bowel obstruction.
64
Most common type of cervical cancer
Squamous cell carcinoma
65
When does neutropaenic sepsis usually present?
1-2 weeks after last cycle of chemo
66
Mechanism of SVCO
direct tumour growth, thrombosis within the vena cava or lymphadenopathy
67
Symptoms of SVCO
The main symptoms are dyspnoea, facial swelling, head fullness and cough. Other symptoms include dysphagia, distended chest and neck veins, upper limb oedema, facial plethora, cyanosis and confusion. These are worse when bending forwards, lying down or raising the arms above the head for 1-2 minutes
68
What is Pemberton's sign?
Symptoms of SVCO are worse when the arms are raised above the head for a couple of mins
69
Diagnostic imaging in SVCO
CT
70
Management of acute SVCO with stridor
ABCDE Sit patient upright Stenting / shunting / thrombolysis
71
Options for management of SVCO
``` ABCDE with O2 and patient sitting upright Treat underlying cancer Dexamethasone Stenting or shunting Thrombolysis ```
72
Common presentations of immunotherapy toxicity
Common presentations include thyroid disease, vitiligo, rash, pneumonitis, colitis, hepatitis, nephritis, uveitis and neuropathy
73
Management of immunotherapy toxicity
